METHODS AND DEVICES FOR LENGTH MANAGEMENT OF CABLES WITHIN FIBER OPTIC CONNECTION DEVICESCROSS-REFERENCE TO RELATED APPLICATIO S

[0001] This application claims priority to U. S. Provisional Patent Application No.63 / 778,789, filed March 27, 2025, entitled " Methods and Devices for Length Management of Cables Within Fiber Optic Connection Devices," which is hereby incorporated by reference in its entirety.FIELD OF THE DISCLOSURE

[0002] The present disclosure relates generally to network communications equipment and, more particularly, to devices, methods, and systems for length management of fiber optic cables incorporated m co-packaged optics module assemblies.BACKGROUND OF THE DISCLOSURE

[0003] Cables, such as those used for communication optical fiber, are often routed within com unications equipment cabinets, connecting devices such as high-performance computing (HPC) modules, server enclosures, and data center (DC) packet switches. These cabinets are designed to guide incoming optical cables and their corresponding fibers into connection terminals in an organized manner.

[0004] While optical fiber cabling has long been used in this way for box-to-box connections in DCs and HPC facilities, its application inside equipment enclosures is an emerging technology, being introduced to meet the growing demand for high-speed, robust, and scalable network solutions. This shift introduces new challenges for box designers and builders, who need to integrate fiber optic infrastructure into their designs. Unlike traditional cabling, fiber optics require careful handling to maintain their reliability and due to their sensitivity to bending. Assemblers, often unfamiliar with these requirements, may inadvertently introduce performance-degrading issues such as micro¬ bends or improper connector seating.

[0005] In the congested surroundings inside functional elements, traditional fiber optic cable management methods are reaching their limits in terms of capacity, precision, and space optimization, requiring new approaches to routing, securing, and maintaining these cables efficiently. Improvements in the foregoing are desired.BRIEF SUMMARY OF THE DISCLOSURE

[0006] In data centers, rack assemblies may include enclosures, such as packet switches, high-performance computing (HPC) modules, and servers, that house network infrastructure, including fiber optic connection devices that facilitate high-speed data transmission. These enclosures need to be configured to accommodate numerous fiber optic cables while ensuring they are properly routed to maintain performance and reliability. Traditionally, these enclosures relied on small pluggable optical modules that plugged into the faceplate of the box. These modules contained the optical transmitters and receivers, along with short fiber optic sections terminating in a connector and adapter, enabling easy connections to external cabling for inter-box communication via a switching architecture. This design allowed for straightforward maintenance and replacement of the optical components within the pluggable modules that were generally less reliable than the other elements inside the box.

[0007] However, as data centers continue to evolve to support increasing bandwidth demands, emerging technologies such as co-packaged optics (CPO) are being implemented to improve energy efficiency and system performance. Unlike traditional pluggable optics, CPO integrates optical components directly inside the enclosure rather than confining them to removable modules. This shift alters how fiber routing is managed within a fiber optic connection device, introducing new challenges for designers and assemblers who may lack experience in handling internal fiber optic cabling. Given the complexity of fiber routing, managing the precise length and / or routing of each cable within the enclosure is beneficial to prevent installation issues and long-term performance degradation.

[0008] One of the main challenges in length management is ensuring that each fiber has an appropriate amount of cable to allow for secure connections, rework, andmaintenance, without creating undue congestion and avoiding degradation in performance such as from manipulation of the cable. If fiber optic cables are too long, they may be improperly arranged within the enclosure, leading to excessive bends or buckling that can weaken the fiber and degrade signal integrity. Conversely, cables that are too short limit flexibility during installation and rework, making it difficult to complete connections without introducing strain. Additionally, variations in cable length due to manufacturing tolerances or adjustments made during assembly further complicate deployment, making a structured and repeatable approach to fiber organization desirable.

[0009] In various embodiments disclosed herein, effective cable length management within these housings is provided by precise routing strategies that account for both manufacturing variations and operational needs. The fiber is laid out in a controlled manner that avoids excessive bending or tight loops while also ensuring accessibility for future maintenance. Without proper organization, cable congestion can lead to increased risk of damage, reduced serviceability, and potential network failures. By carefully managing cable length and routing, fiber optic enclosures can maintain long-term reliability while supporting efficient deployment and rework within data center environments.

[0010] Embodiments of the present disclosure provide various systems, devices, and methods that resolve many of the above noted defects and difficulties. In this regard, various embodiments of the present disclosure provide systems, devices, and methods for effectively managing the length of fiber optic cables within a housing of a fiber optic connection device, ensuring that the cables are routed in an efficient manner, such as by providing length adjustment features that allow variations in the length of the fiber optic cable - with those adjustments being in a controlled manner. These solutions are designed to address the challenges associated with excess or insufficient cable length, preventing issues such as improper bends, compression, or difficulty during rework. By incorporating precise cable length management techniques, the systems ensure reliable performance, ease of maintenance, and long-term durability of the fiber optic infrastructure within data center environments. Additionally, these solutions account for manufacturing variations in cable lengths, providing a structured approach to cable organization that minimizes the risk of signal degradation or damage to the cables.

[0011] Some of the systems, devices, and methods disclosed herein include a first length adjustment feature positioned within a housing of a fiber optic connection device. The first length adjustment feature may be configured to interact with a portion of at least one fiber optic cable and may be configured to enable selectable positioning of the first length adjustment feature to vary a length of the at least one fiber optic cable stored within the housing. The first length adjustment feature allows for precise and controlled length adjustment of the at least one fiber optic cable, ensuring that the portion extending beyond the fiber optic connection device remains consistently uniform and accurately measured.

[0012] Additionally, or alternatively, some of the systems, devices, and methods disclosed herein include a second length adjustment feature positioned within the housing of the fiber optic connection device. The second length adjustment feature may be configured to interact with a portion of the at least one fiber optic cable. In some embodiments, the second length adjustment feature may be reconfigured, or selectively removed from the housing, to release a predetermined length of the at least one fiber optic cable retained within the housing, adding more fiber optic cable length that may extend beyond the fiber optic connection device. The second length adjustment feature may allow for at least two different fiber optic cable lengths, and a plurality of elongated pathways, of the at least one fiber optic cable stored within the interior chamber. In some situations, access to the first length adjustment feature may be restricted to more qualified assemblers, whereas the second length adjustment feature may be utilized by end installers to enable controlled length adjustments.

[0013] In some embodiments, the fiber optic connection device may be positioned within a co-packaged optics equipment box that is configured to enable movement of the fiber optic connection device to facilitate assembly operations and access for making connections. For example, the co-packaged optics equipment box may include a sliding mechanism that enables the fiber optic connection device to slide between a first position, where the fiber optic connection device is positioned away from a front portion of the copackaged optics equipment box to facilitate assembly operations, and a second position, where the fiber optic connection device is in an assembled position. Additionally, or alternatively, the co-packaged optics equipment box may be configured to enable the fiberoptic connection device to rotate between a first position, where the fiber optic connection device is rotated to provide access for making connections, and a second position, where the fiber optic connection device is in an assembled position. In some embodiments, the device may be rotated upwardly. These configurations may facilitate assembly in handling optical fiber by providing controlled and repeatable positioning of the optical infrastructure during the assembly process. In some embodiments, when the fiber optic connection device is in the assembled position, a front portion of the fiber optic connection device having connection ports may form part of a front portion faceplate of the co-packaged optics equipment box, allowing external connections to be made at the faceplate.

[0044] Exemplary embodiments of the present disclosure are described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the present disclosure are shown. Indeed, the present disclosure may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein; rather, these embodiments are provided so that this disclosure satisfies applicable legal requirements. Like reference numerals refer to like elements throughout.

[0045] Due in part to its extremely wide bandwidth and low noise operation, optical fiber is increasingly being used for a variety of applications, including but not limited to broadband voice, video, and data transmission. Fiber optic communications networks may include a number of interconnection points (such as at which multiple optical fibers are interconnected) and / or connection terminals (e.g., network access point (NAP) enclosures, optical network terminals (ONTs), network interface devices (NIDs)). Accordingly, corresponding fiber optic cables may be managed (e.g., routed through, split, reconfigured, connected, etc.) in many different communications equipment cabinets and other enclosures.

[0046] The connection terminals may be used to extend fiber optic communications services to a subscriber. In this regard, fiber optic networks may deliver “fiber-to-the-curb” (FTTC), “fiber-to-the-business” (FTTB), “fiber-to-the-home” (FTTH) and “fiber-to-the-premises” (FTTP), referred to generically as “FTTx”. For example, delivering services tosubscribers in the last mile connection may occur indoors. Different kinds of buildings may require complicated cabling systems, which can include many separated cables, each one connecting one subscriber.

[0047] Co-packaged optics is an emerging technology designed to improve the efficiency and performance of fiber optic communications by integrating optical components directly with application-specific integrated circuits (ASICs), central processing units (CPUs), or graphics processing units (GPUs) within network equipment. The systems and methods disclosed herein are also applicable to near-packaged optics (NPO) configurations, where optical components such as an optical engine are positioned on the printed circuit board (PCB) in proximity to the ASIC rather than being fully integrated into a single co-packaged assembly. Both CPO and NPO configurations involve fiber optic infrastructure inside the equipment enclosure and therefore call for similar fiber and cable management solutions as described herein. Unlike traditional network designs where optical transceivers are located at easily accessible faceplates, CPO extends optical pathways deeper into the equipment enclosure, requiring precise fiber management within the confined spaces of the enclosures. This shift presents new challenges in routing and securing fiber optic cables, as variations in cable length and improper handling can lead to excessive bending, pinching, or damage that compromises signal integrity. Effective length management solutions are desired to ensure reliable connections, facilitate maintenance, and support the growing demand for high-bandwidth, low-latency data transmission in modern fiber optic networks.

[0048] Some interconnection points include enclosures, such as rack assemblies, which are used in places such as data centers, network rooms, central offices, and / or in intent-based networking. For example, fibers are often organized and managed within standardized 19-inch racks (although other size racks are contemplated herein). Such racks are designed to hold and protect fiber optic cables (e.g., fibers). These enclosures are needed for making sure that fiber connections stay strong and reliable, especially in environments like data centers, where lots of data is being transmitted between servers and other equipment.

[0049] Systems and assemblies according to the present disclosure allow for precise management of fiber optic cable length within confined enclosures, ensuring proper routing and organization to maintain signal integrity and facilitate maintenance. Additionally, the disclosed solutions support efficient installation and rework, enabling reliable and scalable fiber optic connections in high-density network environments, including those utilizing co¬ packaged optics technology.

[0050] While some of the illustrated and described embodiments focus on use of various embodiments in rack assemblies, any type of enclosure or structure is contemplated for use with various embodiments. For example, the disclosed systems and assemblies may be employed in many different fiber optic management scenarios, such as in optical fiber distribution hub cabinets, multi-dwelling unit cabinets, front-end and / or back-end cabinets, closures, or other terminals. In some embodiments, various concepts and designs may be easily adjusted for any communications equipment.

[0051] Referring first to FIGs. 1A and 1B, an enclosure 10 is shown. FIG. 1 A shows an enclosure 10 that includes an outer housing 20 and a door 24. FIG. IB shows the enclosure 10 with the door 24 removed. Within the enclosure 10 is a rack assembly 28 that holds a plurality of co-packaged optics assemblies 30. For example, in some embodiments, the plurality of co-packaged optics assemblies 30 may each include a plurality of fiber optic connection devices and one or more cable management components, as will be discussed in greater detail herein. In some embodiments, such enclosures may include, e.g., a 19-inch rack assembly in an environment such as a data center or a network room. The rack assembly 28 may be used to manage cable(s) and / or fiber(s) that connect directly to downstream optical communications equipment, such as network switches or routers, housed in the same 19-inch rack assembly. Although a 19-inch rack assembly in shown in FIGs. 1A-1B, it should be appreciated that the embodiments disclosed herein may include any other type of fiber optic enclosure and are not limited to a 19-inch rack assembly. For example, the concepts presented herein may be scaled for different rack standards such as 21 -inch or 23-inch rack assemblies, or a system that does not utilize a rack at all may be used as well. Further, any dimension or size of the racks or enclosures may be compatiblewith the disclosures herein. For example, various embodiments are compatible with different sized housings, such as 1U, 2U, 4U, 6U, 8U, etc.

[0054] The housing 102 may further include an application-specific integrated circuit (ASIC) 113 at its core, surrounded by one or more photonic chips 114, such as also may be referred to as photonic integrated circuits (PIC). The ASIC-PIC connection enables seamless integration of electronic processing and optical communication, with the ASIC 113 handling data processing and generating electrical signals, while the PIC 114 converts electrical signals into optical signals for high-speed transmission. Furthermore, the housing may further include electronic interface circuits (ETCs) (not shown) conditioning the signals as they pass between the ASIC 113 and the PICs 114, ensuring proper signal integrity and compatibility. Furthermore, the one or more photonic chips 114 in the copackaged optics assembly 100 enables high-speed data transmission by converting electrical signals to optical signals and vice versa, reducing power consumption and latency. The one or more photonic chips 114 also improves signal integrity and efficiency by minimizing energy loss, enhancing bandwidth, and enabling compact integration of a plurality of optical and electronic components. As shown in FIG. 1C, one or more of the fiber optic cables------ each connected to the one or more connection features 122b, 124b, 126b, 128b and a portion of each stored within the housing of the first fiber optic connection device 122, the second fiber optic connection device 124, the third fiber optic connection device 126 and the fourth fiber optic connection device - - -may be connected to the one or more photonic chips 114.

[0055] As shown, the housing 122a of the first fiber optic connection device 122 may be configured to store at least a portion of the fiber optic cable 123. As will be discussed in greater detail below, the first fiber optic connection device 122 may include one or more length adjustment features positioned within the housing 122a and configured to interact with the at least one fiber optic cable 123 extending from the one or more connection features 122b. The one or more length adjustment features are also configured to enable a user to select from a plurality of optional predetermined pathways within the housing 122a, each of the optional predetermined pathways providing for a different length variation ofthe at least one fiber optic cable 123 within the housing 122a. Once a user configures the predetermined length of the fiber optic cable 123 within the housing 122a, the correct predetermined length of the fiber optic cable 123 may then be routed outside of the first fiber optic connection device 122 and directed to the one or more photonic chips 114. A fiber optic cable connecting to a photonic chip 114 may transmit optical signals to and from the chip 114, enabling high-speed data communication. This connection allows the chip 114 to send and receive light-based signals, which are converted to electrical signals for processing or vice versa.

[0056] Additionally, or alternatively, the housing 124a of the second fiber optic connection device 124 may be configured to store at least a portion of fiber optic cable 125. As will be discussed in greater detail below, the second fiber optic connection device 124 may also include one or more length adjustment features positioned within the housing 124a and configured to interact with the at least one fiber optic cable 125 extending from the one or more connection features 124b. The one or more length adjustment features are also configured to enable a user to select from a plurality of optional predetermined pathways within the housing 124a, each of the optional predetermined pathways providing for a different length variation of the at least one fiber optic cable 125 within the housing 124a. Once a user configures the predetermined length of the fiber optic cable 125 within the housing 124a, the correct predetermined length of the fiber optic cable 125 may then also be routed outside of the second fiber optic connection device 124 and routed to the one or more photonic chips 114. As shown, the predetermined length of the fiber optic cable 123 connected between the first fiber optic connection device 122 and the one or more chips 114 may be longer than the predetermined length of the fiber optic cable 125 connected between the second fiber optic connection device 124 and the one or more chips 114.

[0057] The housing 102 may include a plurality of cable routing features 130, 132, 134, 136, 138, 139. The cable routing features 130, 132, 134, 136, 138, 139 organize and secure the one or more fiber optic cables connected to the fiber optic connection devices 122, 124, 126, and 128 at one end and the chip 114 at the other. Additionally, the cable routing features 130, 132, 134, 136, 138, 139 prevent bending, kinking, or signal loss, whilealso maintaining proper alignment and spacing to ensure optimal signal integrity and reliable data transmission. The cable routing features 130, 132, 134, 136, 138, 139 allow for a plurality of pathways between the fiber optic connection devices 122, 124, 126, and 128 and the chip 114.

[0058] The housing 102 may further include one or more power supplies 118a, 118b. The one or more power supplies 118a, 118b in the co-packaged optics assembly 100 provide stable and regulated electrical power to drive the optical and electronic components, ensuring reliable data transmission and system performance. The housing 102 may further include one or more fans 116. The one or more fans 116 dissipate heat by promoting airflow, preventing overheating of the co-packaged optics assembly 100 and ensuring optimal performance of the optical and electronic components described herein.

[0059] In some embodiments, the housing 102 may further include other electrical and optical components, including one or more optical transceivers, and thermal management elements. The housing 102 may also contain interconnects, control circuitry, and power management components to facilitate the transmission of optical signals and ensure stable operation. Additionally, the housing 102 may include electromagnetic shielding and structural supports to protect the internal components from external interference and mechanical stress.

[0060] FIG. 2 illustrates a fiber optic connection device 200 with a cover 204. FIG. 3 shows the fiber optic connection device 200 with the cover 204 removed. The fiber optic connection device 200 may be positioned within the co-packaged optics assembly 100 (see FIG. 1C). In some embodiments, the fiber optic connection device 200 may be positioned in any other type of fiber optic enclosure apparatus.

[0061] The fiber optic connection device 200 comprises a housing 202 having an interior chamber 203 (shown in FIG. 3). The interior chamber 203 of the housing 202 may be configured to store at least a portion of at least one fiber optic cable 231 therein. The fiber optic connection device 200 may further include one or more connection features 206 configured to receive one or more optical fibers from the at least one fiber optic cable. The one or more connection features 206 may be configured to provide connection capabilityto enable data communication with the one or more optical fibers, such as to future connections from the network. In some embodiments, the at least one fiber optic cable 231 extends from the one or more connection features 206 into the interior chamber 203 of the housing 202. Furthermore, in some embodiments, while FIGs. 2-3 depict one fiber optic cable 231 connected to the one or more connection features, any number of fiber optic cables may be contemplated and connected to the one or more connection features. Likewise, while one optical fiber connection is shown extending from the fiber optic cable 231, additional optical fibers may be installed, etc.

[0062] In some embodiments, the housing 202 of the fiber optic connection device 200 comprises connection port 206, which is connectable to the optical fiber(s) of the at least one fiber optic cable (e.g., fiber optic cable 231) that can be organized and stored within the housing 202 (e.g., see FIG. 3). That is, in some embodiments, connection port 206 may include a first connection port 297a, a second connection port 297b, a third connection port 297c, and a fourth connection port 297d. The connection ports 297a-d may also be referred to as adapters which include connectors within. Each of the connection port 206 may be connected to set(s) of the fibers extending from the at least one fiber optic cable, and each of the connection port 206 is connectable to a set of connection cables (not shown). For example, the first connection port 297a is connected to a first set of fibers extending from the at least one fiber optic cable, and a first set of connection cables are plugged into the first connection port 297a such that the first set of connection cables are in optical communication with the first set of fibers. The purpose of connection port 206 may be to connect external devices to a network, via the components within fiber optic connection device 200, as described herein.

[0063] In the illustrated embodiment, each connection port 297a-d has the capacity to connect thirty-two (32) fibers. However, it is within the scope of the present disclosure that any other number of connections may be achieved in other embodiments. For example, another embodiment may include connection ports that connect four fibers to four connection cables.

[0064] FIG. 3 further illustrates the housing 202 of the fiber optic connection device 200 having one or more length adjustment features. In some embodiments, a first lengthadjustment feature 220 may be positioned within the interior chamber of the housing 202. In some embodiments, the first length adjustment feature 220 may be configured to interact with the at least one fiber optic cable 231 extending from the one or more connection features 206. In some embodiments, the first length adjustment feature is configured to enable selectable positioning of the first length adjustment feature 220 relative to the one or more connection features 206 to vary a length of the at least one fiber optic cable 231 stored within the interior chamber of the housing 202.

[0065] In some embodiments, the housing 202 of the fiber optic connection device 200 may further include a second length adjustment feature 230 positioned within the interior chamber of the housing 202. In some embodiments, the interior chamber 203 may be divided into a first interior chamber portion 203a and a second interior chamber portion 203b. The first length adjustment feature 220 may be positioned within the first interior chamber portion 203a and the second length adjustment feature 230 may be positioned within the second interior chamber portion 203b. In an embodiment, the second length adjustment feature 230 may be configured to interact with the at least one fiber optic cable 231 extending from the first length adjustment feature 220. In some embodiments, the second length adjustment feature 230 may be configured to enable selectable removal thereof from the interior chamber to vary the length of the at least one fiber optic cable 231 stored within the interior chamber of the housing 202.

[0066] In some embodiments, the first length adjustment feature 220 may be positioned closer to the one or more connection features 206 than the second length adjustment feature 230. In some embodiments, other positions of the first length adjustment feature 220 relative to the second length adjustment feature 230 may be contemplated. In some embodiments, the interior chamber 203 may be divided into one or more sections by one or more partial barriers. The first length adjustment feature 220 may be separated from the second length adjustment feature 230 by a partial barrier. Thus, in some embodiments, the interior chamber of the housing 202 may be separated into the first interior chamber portion 203a with the first length adjustment feature 220 and the second interior chamber portion 203b with the second length adjustment feature 230. In some embodiments, one end of the partial barrier may create a cable routing gap so that the at least one fiber optic cable 231may be able to pass from the first interior chamber portion 203a to the second interior chamber portion 203b of the housing 202 while maintaining proper organization and minimizing the risk of excessive bending or pinching (e.g., through routing features, such as for bend radius control). In some embodiments, the cable routing gap allows for controlled cable management, ensuring that the pathway between the first length adjustment feature 220 and the second length adjustment feature 230 remain secure and free from obstruction while facilitating efficient installation and maintenance.

[0067] In some embodiments, the second interior chamber portion 203 b may include an enclosure positioned around the second length adjustment feature 230. The enclosure may be designed to organize and store the at least one fiber optic cable 231 received from the first length adjustment feature 220 in a controlled manner, preventing tangling, damage, or disorganization. The enclosure also ensures that the at least one fiber optic cable 231 is maintained within the second interior chamber portion 203b and does not spread or become tangled within the second interior chamber portion 203b region, while maintaining a compact, manageable form.

[0068] The second length adjustment feature 230 may include a cylindrical structure 232 (e.g., a stake or rod) which may be inserted when the fiber optic connection device 200 is first assembled and removed, if necessary, from the housing 202 of the fiber optic connection device 200. The at least one fiber optic cable 231 received from the first length adjustment feature 220 may be routed around, or partially around, the cylindrical structure 232 and guided out of an exit aperture 240. The exit aperture 240 allows the at least one fiber optic cable 231 to exit the fiber optic connection device 200 and be directed to the photonic chip 114 (see FIG. 1 C). As shown in FIG. 3, the second length adjustment feature 230 may include a cable guide wall 236 positioned around and on the outside of the cylindrical structure 232. In some embodiments, the cable guide wall 236 is a cavity that may be molded in the housing 202 along the path of the at least one fiber optic cable 231 that is received from the first length adjustment feature 220, routed partially around the cylindrical structure 232 before being guided out of the exit aperture 240. The cable guide wall 236 supports the at least one fiber optic cable 231 by providing structure and guidance, preventing the at least one fiber optic cable 231 from floating freely within the housing 202interior chamber, and more specifically within the second interior chamber portion 203 b of the housing 202. Thus, the at least one fiber optic cable 231 may be constrained by the cable guide wall 236 within the second length adjustment feature 230 region of the housing 202. Additionally, the cable guide wall 236 aids in enforcing the minimum bend radius of the at least one fiber optic cable 231 in curved sections within the second length adjustment feature 230 region of the housing 202.

[0069] In some embodiments, the removal of the cylindrical structure 232 of the second length adjustment feature 230 from the housing 202 releases a predetermined length of at least one fiber optic cable 231 retained within the interior chamber. The cable guide wall 236 does not impede the release of the at least one fiber optic cable 231 once the second length adjustment feature 230 is removed from the housing 202, Such additional length may be beneficial for an end installer, such as for positioning of the fiber optic connection device 200, among other reasons. Thus, in some embodiments, the second length adjustment feature 230 allows for two cable length variations of the at least one fiber optic cable stored within the interior chamber. In some embodiments, the second length adjustment feature 230 may include a cylindrical structure 232 (e.g., a stake or rod) which may be inserted when the fiber optic connection device 200 is first assembled and removed, if necessary, from the housing 202 to provide extra length for the at least one fiber optic cable 231. The cylindrical structure 232 may also maintain the minimum bend radius of the at least one fiber optic cable 231. In some embodiments, the second length adjustment features and bend radius control features may be configured to turn in their fixtures, or may include a bearing along the portion of their length that contacts the cable to reduce friction. In some embodiments, the second length adjustment feature may comprise a slider that allows continuous adjustment of the cable length rather than discrete removal. In some embodiments, the second length adjustment feature may comprise deformable or breakable structures such as flaps or perforated membranes that define the initial cable path. In some embodiments, the cover 204 of the connection device may include an aperture or hole 210 through the cover 204 so that the cylindrical structure 232 may be removed by a user. In some embodiments, the cylindrical structure 232 may be held in place within the housing 202 and through the cover 204 by a locking mechanism. The locking mechanism mayinclude an open configuration and a close configuration. In the close configuration, the locking mechanism may retain the cylindrical structure 232 of the second length adjustment feature 230 to the housing 202. In the open configuration, the cylindrical structure 232 of the second length adjustment feature 230 may be removed from the housing 202, if necessary. In some embodiments, the locking mechanism may include a screw collar, a retaining clip, a spring pin, among others. The locking mechanism may prevent unintended movement of the cylindrical structure 232, ensuring the cylindrical structure 232 remains securely positioned. In some embodiments, the cylindrical structure 232 may be held in place within the housing 202 and through the cover 204 without a locking mechanism, relying instead on a friction fit or interference fit to maintain its position. In some embodiments, the second length adjustment feature 230 may not be removable but rather reconfigurable such as to a different position or to be otherwise able to release the predetermined length of at least one fiber optic cable 231 retained within the interior chamber of the housing 202. In some embodiments, the structure 232 may include other shaped structures. In some example embodiments, the structure 232 may include any curved shape, straight shape or half cylinder that may be removable or reconfigured, if necessary, from the housing 202 to provide extra length for the at least one fiber optic cable 231.

[0070] In some embodiments, the second length adjustment feature 230 is accessible without removing the cover 204 of the fiber optic connection device 200 and may be removable, for example through the hole 210 in the cover 204, by a box assembler. In some embodiments, an equipment box assembler may be a less experienced worker working in a manufacturing facility with experience of electrical / electronic / mechanical assembly but little experience in handling optical fiber or optical fiber cable. This relatively inexperienced worker is responsible for integrating the pre-assembled fiber optic connection device into the larger equipment enclosure. The equipment box assembler connects the external fiber optic cables from the connection device to terminal points, such as photonic integrated circuits (PICs) or external laser modules (ELs). This role focuses on proper cable placement and connection rather than detailed fiber management, allowing for more efficient and scalable deployment of fiber optic infrastructure. In someembodiments, the assembly procedure may require, or the equipment box assembler may determine, that in order to connect the external fiber optic cables from the connection device to the various terminal points, more fiber optic cable length is desired. In some embodiments, the equipment assembler may remove the cylindrical structure 232 from the housing 202, thus releasing a predetermined length of at least one fiber optic cable retained within the interior chamber of the housing 202. In some embodiments, the predetermined length of at least one fiber optic cable retained within the interior chamber of the housing 202 may be determined by an expert device assembler, as will be discussed in greater detail below.

[0071] In some embodiments, the first length adjustment feature 220 may be configured to enable a plurality of selectable positions of the first length adjustment feature 220 to vary the length of the at least one fiber optic cable 231 stored within the interior chamber 203 of the housing 202. In some embodiments, the first length adjustment feature 220 may enable length adjustments with tolerances of less than approximately 1 mm. In some embodiments, the first length adjustment feature 220 may enable length adjustments with tolerances of less than approximately 0.5 mm. The range of adjustment of the at least one fiber optic cable 231 that may be accomplished by the first length adjustment feature 220 may typically be less than that which can be done by the second length adjustment feature 230. Additionally, the adjustment steps of the first length adjustment feature 220 may be minute and deterministic in order to precisely adjust the length of the at least one fiber optic cable 231 with the first length adjustment feature 220. In contrast, the second length adjustment feature 230 allows for bigger length adjustment of the at least one fiber optic cable 231 to accommodate different external cable deployment paths. In some embodiments, each of the plurality of selectable positions corresponds to one of a plurality of elongated pathways of the at least one fiber optic cable 231 stored within the interior chamber of the housing 202. In some embodiments, when the first length adjustment feature 220 is in a first position of the plurality of selectable positions, the at least one fiber optic cable 231 includes a first length within the interior chamber along a first predetermined pathway. In an embodiment, when the first length adjustment feature 220 is in a second position, the at least one fiber optic cable defines a second length within theinterior chamber along a second predetermined pathway. In some embodiments, the second predetermined pathway is shorter than the first predetermined pathway.

[0072] In some embodiments, the first length adjustment feature 220 allows for adjustment of the length of the at least one fiber optic cable 231 to ensure the appropriate length of the at least one fiber optic cable 231 is positioned outside of the housing 202 connecting to further optical components. In some embodiments, this precision is beneficial for enabling automated assembly processes, particularly for delivering a fiber array unit (FAU) in a precise location for connection to a photonic integrated circuit (PIC). In some embodiments, a device assembler may interact with the first length adjustment feature 220. The device assembler may be defined as a skilled technician responsible for assembling the fiber optic connection device 200 by carefully routing and securing fiber optic cables within the housing. The device assembler ensures precise length adjustments, organizes fiber paths to prevent excessive bending or pinching, and prepares the fiber optic connection device 200 for deployment. This role tends to include expertise in fiber optic handling and length management to guarantee desired performance and reliability of the connections.

[0073] In some embodiments, a device assembler may select a position for the first length adjustment feature 220, from the plurality of selectable positions, which correspond to the one of a plurality of elongated pathways of the at least one fiber optic cable 231 stored within the interior chamber and adjust the length of the at least one fiber optic cable 231 by storing a length of the at least one fiber optic cable 231 within the first length adjustment feature 220. Thus, in some embodiments, the device assembler may store an adjustable amount of the at least one fiber optic cable 231 within the first length adjustment feature 220.

[0074] FIG. 4A illustrates the first length adjustment feature 220 including at least one engagement feature 229 configured to interact with a corresponding receiving feature. In some embodiments, the first length adjustment feature 220 includes a cable carrier 222 with a portion of the at least one fiber optic cable 231 fixed, or positioned or lying, therein. In some embodiments, the cable carrier may be opened or otherwise configured to allow the at least one fiber optic cable 231 to be dropped into the cable carrier 222 or otherwisecaptured by the cable carrier 222. In some example embodiments, the cable carrier 222 may include a channel that holds the at least one fiber optic cable 231. In some embodiments, the cable carrier 222 is movable between the plurality of selectable positions. In some embodiments, the cable carrier 222 may define at least one engagement feature 229 configured to interact with a corresponding receiving feature 226 at each of the plurality of selectable positions. In some embodiments, as shown in FIG. 4A, the engagement feature 229 comprises a teeth-shaped structure and the corresponding receiving feature 226 includes a teeth-shaped structure that interacts with the engagement feature 229 (although multiple features are shown). The teeth-shaped structure may be a linear gear-like structure; however, other shapes may be contemplated. In an embodiment, the device assembler may adjust the position of the cable carrier 222, and therefore the fiber optic cable 231, to interact with a different receiving feature 226 so as to manage the length of the fiber optic cable - so as to enable, for example, fine adjustments of the length.

[0075] FIG. 4B illustrates the first length adjustment feature 220 including a first cable carrier 221 and a second cable carrier 223 placed on top of one another (e.g., in parallel horizontal planes). In some embodiments, the at least one fiber optic cable may comprise a first fiber optic cable 231a and a second fiber optic cable 231b. In some embodiments, the first length adjustment feature 220 comprises a first cable carrier 221 and a second cable carrier 223. In some embodiments, the first cable carrier 221 may include a portion of the first fiber optic cable 231a positioned therein and the second cable carrier 223 may include a portion of the second fiber optic cable 231b positioned therein. In some embodiments, each of the first cable carrier 221 and the second cable carrier 223 may be configured to be movable between the plurality of selectable positions (e.g., respective selectable positions in their corresponding horizontal planes). In some embodiments, each of the first cable earner 221 and the second cable earner 223 may define at least one engagement feature configured to interact with a corresponding receiving feature at each of the plurality of selectable positions. In some embodiments, the first cable carrier 221 may be positioned on top of the second cable carrier 223 allowing for independent length variation of the first fiber optic cable 231 and the second fiber optic cable 231b stored within the interior chamber of the housing 202. While FIG. 4B demonstrates a first cablecarrier 221 positioned on top of a second cable carrier 223 allowing for independent length variation of each fiber optic cable positioned therein, any number of cable carriers each having a portion of a fiber optic cable positioned therein may be positioned on top of one another and may be contemplated.

[0076] Thus, in some embodiments, to accommodate more than one optical cable in the first length adjustment feature 220, sets of cable carriers, e.g., the first cable carrier 221 and the second cable carrier 223 may be arranged in a stacked configuration on top of or in proximity to each other, one cable carrier for each optical cable. In some embodiments, the narrowest cable earner may be positioned at the bottom of the stack closest to the bottom portion of the housing 202 and the widest cable earner at the top of the stack closest to the cover of the housing 202. In some embodiments, this allows for independent length adjustment of each of fiber optical cables 231a, 231b.

[0077] In some embodiments, the cover 204 of the housing 202, or a portion of the cover 204, may be clear so that the device assembler or the box assembler may view the interior chamber of the housing 202 and one or both of the first length adjustment feature 220 and the second length adjustment feature 230 to aid in detection of issues with the deployment of the optical cables 231 a, 23 lb, such as fiber pathway problems, or rework of the optical cables 231a, 231b, if needed. In some embodiments, the housing 202 may further include an enclosure which restricts access to the first length adjustment feature 220. Thus, once the device assembler has adjusted the length of the at least one fiber optic cable 231, access to the first length adjustment feature 220 may be restricted so only the device assembler may utilize the first length adjustment feature. In some embodiments, the cover or a portion thereof may operate to provide that restricted access, while other restriction means are also contemplated herein.

[0078] In some embodiments, a housing of a fiber optic connection device may include the first length adjustment feature 220 without the need for the second length adjustment feature 230. In some embodiments, a housing of a fiber optic connection device may include a plurality of the first length adjustment features positioned within the interior chamber. In some embodiments, the housing of the fiber optic connection device may include the second length adjustment feature 230 without the need for the first lengthadjustment feature 220. In some embodiments, a housing of a fiber optic connection device may include a plurality of the second length adjustment features positioned within the interior chamber. In an example embodiment, if a housing of a fiber optic connection device does not include a second length adjustment feature 230, the at least one fiber optic cable 231 may be secured by a locking point, or locking structure, where the at least one fiber optic cable 231 may exit the fiber optic connection device. The locking point is a designated location where the at least one fiber optic cable 231 exits the fiber optic connection device. Thus, the locking point may direct the at least one fiber optic cable 231 from the fiber optic connection device. This locking point may serve to prevent unintended feeding of the at least one fiber optic cable 231 into or out of the fiber optic connection device, ensuring that the at least one fiber optic cable 231 remains securely in place. In some embodiments, grommets or other fixtures may be introduced at the end of the assembly process to prevent the external portion of the at least one fiber optic cable 231 from being further pulled from or fed into the fiber optic connection device. Each cable may have its own separate locking structure, in order to facilitate the removal and replacement of one of the at least one fiber optic cable 231 without affecting the other of the at least one fiber optic cable 231, as may be needed in the event of a failure of one of the optical links in the fiber optic connection device. Thus, this separation enables efficient maintenance in the event of a failure of one of the at least one fiber optic cable 231.

[0079] FIG. 5 illustrates a housing 302 of the fiber optic connection device 300 including a plurality of first length adjustment features 324, 326. In some embodiments, the housing 302 of the fiber optic connection device 300 may include an interior chamber 303 configured to store at least a portion of at least one fiber optic cable therein. As shown in FIG. 5, the housing includes fiber optic cables 332, 334, 336, 338, 340, 341. The fiber optic connection device may further include one or more connection features 397a, 397b, 397c, 397d for receiving one or more optical fibers from the fiber optic cables 332, 334, 336, 338, 340 and for providing connection capability to enable data communication from the one or more optical fibers. In some embodiments, the fiber optic cables 332, 334, 336, 338, 340 extend from the one or more connection features 397a, 397b, 397c, 397d into the interior chamber 303 of the housing 302. In some embodiments, the plurality of first lengthadjustment features 324, 326 may be configured to enable a plurality of selectable positions of the first length adjustment features 324, 326 to vary the length of the fiber optic cables 332, 334, 336, 338, 340 stored within the interior chamber.

[0080] The housing 302 may further include bend radius control features 342a, 342b, 342c. The bend radius control features 342a, 342b, 342c help manage fiber optic cable routing by ensuring that fiber optic cables 332, 334, 336, 338, 340 are not bent beyond their minimum allowable bend radius. These features prevent excessive bending, which can otherwise cause signal loss, fiber damage, or long-term reliability issues. In some embodiments, the bend radius control features 342a, 342b, 342c, may include curved guides, channels, spools, or retention clips that direct fiber paths within the housing 302, ensuring smooth transitions and compliance with fiber bend radius requirements. In some embodiments, by incorporating these features, the fiber optic connection device maintains optical performance while allowing for efficient cable organization and length management. In some embodiments, the bend radius control features 342a, 342b, 342c may be fixed structures. In some embodiments, the bend radius control features 342a, 342b, 342c may include some freedom to turn within the housing 302, In some embodiments, the cable routing within the housing 302 may utilize three-dimensional paths including oblique or vertical sections for additional storage capacity, particularly when using bend-insensitive fiber, which allows this to be done in a relatively small housing height.

[0081] FIG. 5 further illustrates that adjustments may be made even when cables are brought together from different systems, such as may occur, for example, when polarization-maintaining fibers from an external source, such as a laser module, are combined with optical fibers from the one or more connection features for connection therefrom, such as to a photonic integrated circuit (PIC). For example, FIG. 5 illustrates a first fiber optic cable 334 entering from the back, top, left and interacting with a first length adjustment feature 326 before being further managed, such as via one or more bend radius control features 342b and 342a. The first fiber optic cable 334 is then directed via a Y-harness to combine with one or more of the fiber optic cables 336, 338, 340, 341, which each interact with their own separate first length adjustment feature 324 and corresponding bend radius control feature 342c. FIG. 5 further illustrates the fiber optic cable 332 havingthe common trunk of a Y structure, that for example would be formed by the bundling together of fibers from the fiber optic cables 334 and 341. The fiber optic cables 334 and 341 are the branches of the Y, and their lengths are controlled by the first length adjustment features 326 and 324 respectively. The furcation F is where the branches join the trunk. The first length adjustment feature 324 may be used to control the length of the fiber optic cable 332 that is outside the fiber optic connection device.

[0082] Feature F is a furcation structure that constitutes the branching region of the Y-branch portions where fiber optic cable 334 joins one or more of the other fiber optic cables 336, 338, 340 and / or 341. In some embodiments, the furcation structure F enables length adjustment of the Y branches. As used herein, furcation refers to the process of reinforcing and protecting individual optical fibers by enclosing them in a furcation tube or sleeve. This may be done when fibers are separated from a multi-fiber cable for easier handling, termination, or splicing. Furcation helps prevent fiber breakage, minimizes stress on delicate fibers, and improves overall durability during installation and maintenance. Furcation is a structure in which at least two fiber optic cables on one side are combined into at least one cable on the other. As shown in FIG, 5, the design of the fiber optic connection device and in particular its capacity for length variations is such that the furcation F remains within the housing 302. In some embodiments, there may be multiple furcations within the housing, and adjustment will generally leave each furcation at a distinct position within the housing. With careful bend radius control, one or both of the Y-branch legs may exit through the top or bottom walls of the housing. While a first fiber optic cable 334 is shown, additionally, or alternatively, one or more cables may enter at the same or other positions and furcate with other fiber optic cables. The length adjustment feature 326 would then be a stacked structure, as is shown in FIG. 4B, allowing independent adjustment of each cable.
