FIELD OF INVENTION

[0003] The disclosure addresses fiber optic devices that provide at least one optical connection port along with methods for making the same. More specifically, the disclosure addresses fiber optic connection ports and methods for making the same connection port. It includes the technique of securing one or more associated optical connector security ports along with BACKGROUND OF THE INVENTION [00'04] Fiber optics is being used more and more for a variety of applications, including but not limited to broadband voice, video, and data transmission. As bandwidth demands increase, fiber optics is migrating deeper into communication networks, such as fiber for local applications like FTTx, 5G, and similar technologies. As fiber optics were penetrated deeper into communication networks, the need to make robust optical connections in outdoor applications in a quick and easy way became evident. To address this need for fast, reliable, and robust optical connections in communication networks, reinforced fiber optic connectors were developed, such as a plug connector. QptlTap®. [00050 Multi-ports were also developed to make an optical connection with hardened connectors. Prior art multi-ports have a plurality of receptacles mounted through a housing wall to protect an inner connector within the housing that makes an optical connection to the external hardened connector of the branch or drop cable.

[0006] Different drop or branch cables may require different lengths to reach the desired connection location. With factory-terminated solutions, several drop cable lengths are typically offered, and the user can use the cable length required for the link length. However, this may require the vessel to stock several drop cables of varying lengths and a large amount of loose cable storage if the lengths do not match the required link length.

[0007] Consequently, there is an unmet need for devices that allow flexibility for network operators to quickly and easily make optical connections to extend the reach of an optical network while also addressing concerns related to limited space, organization, or aesthetics.

DETAILED DESCRIPTION OF THE INVENTION [0'051] The disclosure methods will now be discussed in detail, examples of which are illustrated in the accompanying drawings. Where possible, similar reference numbers will be used to refer to similar components or parts.

[0052] The device concepts described herein are suitable for providing at least one optical connection for indoor, outdoor, or other environments, as desired. Generally speaking, the devices described and explained in the exemplary embodiments are extension ports, but the concepts described may be used with any suitable device as appropriate. As used herein, the term "extei" means any device comprising a first connection port for receiving an optical fiber connector and making an optical connection. In one embodiment, the extension port has a first connection port and a second connection port that are aligned to make an optical connection between two external optical fiber connectors.Therefore, the extension port can be used to customize or extend the length of an optical link by using two cables connected through the extension port, thus providing even greater flexibility to the network provider. In other configurations, the extension port can be attached to a cable tie for the optical connection with an external connector. The connection port also has a safety feature associated with at least one connection port to secure and release the fiber optic connector. For example, the extension port may also include other components such as active components, such as a wireless sub-assembly device that has electronic components for transmitting or receiving a signal arranged within the extension port housing.

[0053] The concepts described herein advantageously permit compact form factors for the extension ports and may also optionally include at least one connection port comprising an encoding portion for aligning the fiber optic connector with the safety feature associated with the connection port. Although the extension ports are shown and described for a single in-line connection, the concepts are scalable to many in-line connection ports on a single device in a variety of arrangements or constructions. The safety features described herein for devices that couple directly with a portion of the connector without conventional structures such as prior art devices that require the twisting of a coupling nut, bayonet, or the like.As used herein, the safety feature excludes threads and features that cooperate with bayonets in a connector. Therefore, the described devices can allow the connection port to be closely spaced and can result in small devices since the space and structure required to convert a threaded union nut or bayonet is not needed. Compact form factors can allow the placement of devices in confined spaces in indoor, outdoor, buried, aerial, industrial, or other applications, while advantageously providing a device that has at least one connection port with a robust and reliable optical connection in a replaceable and reliable manner. The described devices. 2.5" organizers can also be aesthetically pleasing. These organizers can also be used with expansion ports to provide organization for a variety of expansion ports, including those with optical connections. [0O54] The described devices are simple and elegant in design. They comprise at least one connection port and a safety feature associated with that port, suitable for retaining an external fiber optic connector received through it. A coding portion of the connection port can cooperate with coding on a complementary external fiber optic connector to prevent damage to the connection port by inhibiting the insertion of an incompatible connector, while also ensuring proper rotational alignment to secure the fiber optic connector. The coding portion can also assist the user during blind insertion of the connector into the device's connection port by determining the correct rotational orientation relative to the port when line of sight is not possible or practical for alignment.The encoding portion can be an additive encoding portion to the primitive geometric round shape of the 233 pass zone of the connection port, such as a male encoding. However, the concepts for the 236 connection ports of devices can be modified for different connector designs without an encoding portion, also optical character extension in more elements.

[0055] The concepts described herein advantageously permit quick and easy connection and retention by inserting the fiber optic connectors directly into the device's connection port without the need or space considerations for rotating a threaded coupling nut or bayonet to retain the external connector. Generally speaking, the safety features described for use with ports herein may comprise one or at least one component that moves to release or secure the external fiber optic connector to the device. Specifically, the safety feature is capable of moving within the housing. As used herein, the term safety feature excludes threaded portions or features for securing a bayonet disposed on a connector.

[0056] Since the connector indentations used with the described devices do not require the bulkiness of a coupling nut or bayonet, the fiber optic connectors used with the devices described herein can also be significantly smaller than conventional 25 fiber optic connectors. [0057; The described devices comprise a safety feature for directly engaging with a suitable portion of an external fiber optic connector housing or similar component to secure an optical connection to the device. Different variations of the concepts are discussed in more detail below. The structure for securing the fiber optic connectors to the described devices allows for much smaller indentations for both the devices and the connectors PE fiber optics along with a fast connection feature. Although shown as simplex devices, the device can also have a dense array of connection ports within a housing, such as duplex designs or beyond if desired. The revealed concepts advantageously allow a scalable and relatively dense and organized array of connection ports in a relatively small form factor, while still being rugged for demanding environments. [0058; The concepts described in this document are suitable for optical distribution networks, such as fiber-to-the-home or 5G applications, but are equally applicable to other optical applications, including indoor, automotive, industrial, wireless, or other suitable applications. Additionally, the concepts described can be used with any suitable fiber optic connector indentation that cooperates with the device's safety features. Various device designs, constructions, or features are described in more detail as discussed herein and may be modified or varied as needed.]

[0059] FIGURE 1 is an exploded view of the explanatory extension port 200 comprising at least one connection port 230 for making optical connections. In general terms, the extension port 200 comprising at least one connection port 236 is a portion of a housing 210 of the device. By way of explanation, at least one port The 6 connection is molded as a portion of the housing

[0060] In general terms, the extension port 200 15 comprises a housing 210 comprising a body 232 and one or more connection ports 236 disposed at a first end or portion 212 of the extension port 200. The connection ports 236 are configured to receive and retain external optical fiber connectors 10, as shown in FIGURE 2, to make one or more optical connections within the extension port 200. In the embodiment of FIGURE 1, the optical fiber connectors 10 are received from each end of the extension port 200 to make an optical connection between the optical fiber connectors 10 within the device. Although single-fiber connectors 10 are shown, the concepts can also be used with multi-fiber connectors.

[0061] The 200 extension port of FIGURE 1 comprises a first connection port 236 and a second connection port 200' that are in line or aligned to make an optical connection between the 10 optical fiber connectors inserted from the extension ends. In other embodiments, having a fixed cable 100 in a single connector to originate an optical fixed cable such as the respective port 200 of the extension port can end and an optical connection port 236 with fibers as shown in FIGURE 2A.

[0062] The connection ports 236 each comprise a respective optical connector opening 238 extending from an outer surface 234 of the extension port 200 into a cavity 216 of the extension port 200 and defining a connection port pass-through zone 233. At least one safety feature 310 is associated with the connection port pass-through zone 233 to cooperate with the external fiber optic connector 10. The safety feature is movable to release or secure the external fiber optic connector 10. One more pass-through zone 245 of the respective safety feature, as shown in FIGURE 1, extends from the outer surface 234 of the extension port 200 and cooperates with the respective connection port pass-through zone 233 of the extension port 200. The respective 310 security features are associated with the connection port's pass zone 233 and may have a portion of the 310 security feature disposed within a portion of the pass zone 245 of the extension port's 200 security feature 5.

[0063] Optical connections to the 200 extension ports are made by inserting one or more suitable external fiber optic connectors 10 into the respective connection port pass-through zone 233 as desired. 10 Specifically, the connection port pass-through zone 233 is configured to receive a suitable external fiber optic connector 10 (hereafter referred to as the connector) from a fiber optic cable assembly 100 (hereafter referred to as the cable assembly). Each connection port pass-through zone 233 is associated with a locking feature 310 to retain (e.g., secure) the connector 10 in the 200 extension port.The 310 safety feature advantageously allows the user to make a quick and easy optical connection within the 236 port of the 200 extension port by pushing the connector into the port until it is secured. The 310 safety feature can function to provide a connector release feature when: actuated, such as by pushing down.

[0064] Specifically, connector 10 can be retained 5. Insert the connector 10 into the respective connection port 236 of the device by pushing and fully seating it, as shown in Figure 2. To release the connector 10 from the respective connection port 236, the safety feature 310 is actuated by pressing down to move the safety feature 310 a suitable distance, thereby releasing the safety feature from the connector housing and allowing the connector to be removed from the connection port 236. In other words, at least one safety feature 310 is capable of releasing the connector 10 when moved within a portion of a safety feature passage zone 245. The complete insertion and automatic retention of the connector 10 can advantageously allow for one-handed installation of the connector 10 simply by pushing the connector into the connection port 236.The disclosed 200 series ports achieve this connector retention feature after full insertion by skewing the safety feature to a retained position. However, other operating modes for retaining and releasing the connector are possible according to the concepts described. For example, the 310 safety feature may be designed to require an action to insert the connector; however, this may require a two-handed operation.

[0065] The 310 safety feature may be designed to maintain a minimum pull-out force for connector 10. In some configurations, the pull-out force may be selected to release connector 10 before damage to the device or connector 10 occurs. For example, the 310 safety feature associated with connection port 236 may require a pull-out force of approximately 50 pounds (approximately 220 N) before connector 10 is released. Similarly, the 310 safety feature may provide a lateral pull-out force for connector 10 to also inhibit damage. For example, the 310 safety feature associated with connection port 236 may provide a lateral pull-out force of approximately 25 pounds (approximately 110 N) before connector 10 is released. Of course, other pull-out forces such as 75 pounds (approximately 330 N) or 100 pounds (approximately 440 N) are possible along with other lateral pull-out forces.

[0066] The 310 safety features described herein can take many different constructions or configurations. For example, the 310 safety features can be formed from a single component as shown in FIGURE 1 or from a plurality of components as shown in FIGURE 19. In addition, the 310 safety features or portions of the 310 safety features can be constructed as subassemblies such as shown in FIGURE 19 to facilitate assembly. Still other variations are possible. FIGURE 13 represents a single 310M safety feature that has opposing locking features that cooperate with mating connection ports 236.

[0067] In general terms, the extension ports 200 comprising at least one connection port 236 defined by an optical connector opening 238 extending into a cavity 216 of the extension port 200 10 together with a security feature 310 associated with the connection port 236.

[0068] More specifically, FIGURE 1 is an exploded view of the extension port 200 comprising at least one connection port 236 disposed in the extension port 200, with the connection port 236 defined by an opening 238 of the optical connector extending from an outer surface 234 of the extension port 200 into a cavity 216 of the extension port 200 and defining a connection port pass-through zone 233. The extension port 20 also comprises at least one safety feature pass-through zone 245 to receive at least a portion of the safety feature 310. The safety feature 310 is deflected into a retention position using the respective spring members 310R. The safety feature pass-through zone 245 extends from the outer surface 234 of the extension port 200.This 200 extension port comprises a 210 housing having a first portion 210A and a second portion 210B together with a 230A adapter assembly. (0Ό69] FIGURE 1 represents the connectors 10 aligned at opposite ends of the extension port 200 for insertion into the respective connection ports 236, and FIGURE 2 represents a plurality of connectors 10 retained within the respective connection ports 236 of the assembled extension port 200. As shown in FIGURE 2A, the extension ports 200 can have a fixed clamping cable 100 connected at one end and an optical mating connection port 236 to receive the connector 10 at the other end, according to the concepts described.

[0070] For illustrative purposes, the one or more connection ports 236 and the one or more pass-through zone 245 of the safety feature are a portion of the housing 210. Illustratively, FIGURES 1 and 2 represent the extension port 200 comprising a housing 210 comprising a body 232 with a first connection port 236 disposed at a first end or portion 212 and a second connection port 236' disposed at an opposite end. Each connection port 236, 236' comprises a respective optical connector opening 238. The optical connector openings extend from an outer surface 234 of the housing 210 of the extension port 200 into a cavity 216 and define a respective connection port pass-through zone 233, 233'. One or more respective safety feature 5 pass-through zones 24 5 extend from the outer surface 234 of the housing 210 to cooperate with the respective connection port 23.3 pass-through zone 233'.The second pass-through zone (233') of the connection port is aligned with the first pass-through zone (233) of the connection port so that the respective external connectors can be optically coupled using the extension port 200. As shown in FIGURE 1, the housing 210 consists of a first portion 210I and a second portion 210B, but other arrangements for the housing 210 are possible.

[0071] FIGURE 3 is an exploded view showing the second portion 210B of the housing 210 removed from the first portion 210A and showing the internal assembly of the extension port 200. FIGURES 3 and 4 show the assembly of the extension port 200 of FIGURE 1, FIGURE Figure 5 shows a longitudinal cross-section through the pass-through zone 233 of the connection port of an assembled extension port 200 without connectors attached.

[0072] As shown in FIGURE 5, the feature Safety 310 is diverted to a holding position. Specifically, the safety feature 310 is deflected in an upward direction using a characteristic elastic safety member 310R that is positioned between the fixing feature 310 and the shell 210. Consequently, a portion of the safety feature 310 is able to move within a portion of the safety feature's passage zone 245. As shown, a sealing feature 310S is disposed within the safety feature 310. The sealing feature 310S provides a seal between the safety feature 310 and the safety feature's passage zone 245 to prevent dirt, dust, and debris from entering the device.

[0073] As best represented in FIGURE 5, this connection port 233 pass zone may comprise a 233KP encoding portion as part of the extension port 200. As shown, the 233KP encoding portion is disposed forward of the security feature 310 (i.e., before) in the connection port 233 pass zone above the pass zone entry. The 233KP encoding portion may have any suitable location in the connection port 233 pass zone forward of the security feature. As shown, the extension port 200 has security features 310 associated with each connection port 233 pass zone that cooperate with a portion of the security feature 245 pass zone. In this configuration, the safety feature 310 is a push-button actuator formed as a single component with the locking feature 31.0 L.

[0074] The extension port may also have a 233KP encoding portion disposed on the side of the opening 238 of the optical connector of the security feature 310. The 233KP encoding portion inhibits the insertion of a 236 connection port into the non-compliant connector, thereby inhibiting damage that may be caused to the device. Suitable connectors 10 have a complementary encoding feature that cooperates with the 233KP encoding portion of the extension port 200. The 233KP encoding portion may be a protrusion or additive feature 15 disposed within the passage zone 233 of the connection port on the side of the opening 238 of the optical connector of the security feature 310 and may assume several different configurations when used. For example, the 233KP encoding portion may be a simple 20 protrusion as shown.In other configurations, the 233KP portion of the encoding may take the form of a D-shaped opening to allow only a suitable '10 connector with a complementary feature to be inserted into the 236 connection port. The 233KP portion of the 25 encoding may also assist with the blind mating of a '10 connector into the 236 connection port, as it only permits further insertion into the 236 connection port when the connector is in the correct rotational orientation.

[0075] The extension port 200 of FIGURE 1 also comprises at least one adapter assembly 230A aligned with one or more of the respective connection ports 236 when assembled. The adapter assembly 23QA is suitable for aligning the respective ferrules of the connectors 10 that are inserted into the connection ports 236. The assembly The 230A adapter may comprise a 230FS ferrule sleeve, an adapter housing formed from one or more 23OH components, and an elastic 230R member as shown in FIGURES 1 and 3. The 230FS ferrule sleeve receives a 15 portion of the respective 10F ferrule from connectors 10 for precision alignment.

[0076] . Figures 3 and 4 depict the assembly of the extension port 200 of Figure 1. Figure 3 depicts the safety feature 310 being aligned for installation within the safety feature pass-through zone 245 of the first, housing portion 210A. As shown, the safety feature 310 encoding features 310K (Figure 10-12) are aligned with the safety feature pass-through zone 245 features, which only permits assembly in one orientation for the correct orientation of the locking feature 310L in the extension port 200. Figure 3 also shows the adapter 23IA in an exploded view before alignment and installation within the saddle 210D of the first housing portion 2 LOA. 210. Once seated, the elastic member 230.R of the adapter 230A deflects the housing components 210Ή outwards and provides the ability for the ferrule sleeve 230FS or adapter 230A to float relative to the housing 210. Floating means that the 230A adapter can have slight movement in the XY plane for alignment, and excessive displacement in the Z direction along the connector insertion axis can be inhibited so that proper alignment can be made between the mating connectors. Once the 230A adapter is installed within the first portion 2.1 OA, the thrust force on the housing components 230H holds the 230A adapter in place until the second portion 2108 of the housing 210 is attached as shown in FIGURE 5 [007 7] In other forms, 230A adapters may be formed from various components, but some adapters or portions thereof may also be formed integrally, with the extension port.

[0078] FIGURE 4 represents a partial view 25- Assembled extension port 200 showing the adapter 230A installed within the first portion 210A of the housing 210, and the respective safety feature spring members 310R positioned in an inner portion of the safety feature 310 before the second portion 210B of the housing 210 is attached to trap the safety feature spring members in place. The safety feature 310 may have a lower recess 310B.R or ring to seat the safety feature spring members 310R and focus the restoring force on the safety feature 310 as best shown in FIGURE 5. Subsequently, the second portion 210B of the housing 210 may be attached to the first portion 210A in a suitable manner using a sealing element 290 or not. 5

[0079] In this embodiment, the security feature 310 comprises a hole 310B that, when assembled, is aligned with at least one pass-through zone 233 of the connection port, as best shown in FIGURE 5. The hole 310B is sized to receive a suitable connector 10 through it to secure it for optical connectivity. Holes or openings through the security feature 310 may have any shape or geometry suitable to cooperate with their respective connector. As used herein, the hole may have any desired suitable shape, including features on the hole surface for engaging with a connector to secure it. [O080] In some embodiments, the safety feature 310 is capable of moving to an open position when a suitable connector 10 is inserted into the through-path area 233 of the connection port. When the connector 10 is fully inserted into the through-path area 233 of the connector port, the safety feature 310 is capable of moving to the retaining position automatically. Consequently, the connector 10 is secured within the connection port 236 by securing the feature 310 without turning a coupling nut or bayonet similar to devices of the prior art. In other words, the safety feature 310 moves from the retaining position 15 to an open position as a suitable connector 10 is inserted into the connection port 236.Please note that when connector 10 is fully seated, the safety feature 310 is retracted to the retaining position to secure connector 10 within connection port 236. The safety feature's pass-through zone 245 is arranged transversely to a longitudinal axis of the extension port 200, but other arrangements are possible. Other safety features may function similarly, but use an opening instead of a hole that receives the connector through it.

[0081] As shown in FIGURE 5, the safety feature 310 comprises a locking feature 310L. The locking feature 310L cooperates with a portion of connector 10 when fully inserted into the connection port 236 to secure it. Specifically, the connector housing 20 of connector 10 may have a cooperating geometry that engages the locking feature 310L of the safety feature 310. In this embodiment, the safety feature 310 comprises a hole 310B that is respectively aligned with the through-area 233 of the respective connector port, as shown in FIGURE 5, when assembled. The hole 310B is dimensioned to receive a portion of connector 10 through it.FIGURES 1 and 2 are longitudinal cross-section views of the 200 extension port depicting the 236 optical connection port of the 200 extension port with a 10 connector retained thereon.

[0082] As depicted in this embodiment, the locking feature 310L is disposed within bore 310B. Specifically, the locking feature 310L comprises a ramp in this embodiment. The ramp is integrally formed in a portion of bore 310B with the ramp angled upward when viewed into the connection port 236. The ramp enables the connector 10 to push and displace the safety feature 310 downward against the elastic member 310R of the safety feature as the connector 10 is inserted into the connection port 236 as shown. The ramp may have any suitable geometry 5, such as a retaining surface, such as a projection on the rear portion 1, or the ramp may lead to a flat portion before the retaining surface. Once the locking feature 310L of the safety feature 310 is aligned with 1.The cooperative geometry of the 10 locking feature 20L of connector 10, then the safety feature 310 is moved so that the locking feature 310L engages the locking feature 20L of connector 10 as shown in FIGURES 7-9. Detailed views of the safety feature 310 25 of FIGURE 1 are shown in FIGURES 10-12.

[0083] The seal between the housing components 210 may comprise a (non-visible) sealing element disposed between the components. The seal may comprise a groove in one portion of the housing that cooperates with a tab in the other portion of the housing 210. The grooves may extend around the perimeter of the sealing surface. The grooves may receive one or more appropriately sized O-rings or gaskets for the weatherproof extension port 200. The O-rings are sized appropriately to create a seal between the housing components 210. By way of example, suitable O-rings may be compression O-rings to maintain a weatherproof seal. Other embodiments may use suitable adhesive welding or welding of the materials, such as ultrasonic or induction welding, with appropriate materials to seal the extension port 200.

[0084] FIGURE 6 represents a perspective view showing details of the second portion 21.0B of the housing 210 of FIGURE 1. The second portion 210B of the housing 210 comprises at least one pin 210P disposed within a compartment 210SP of the safety member. The pin 210P and the compartment 210SP of the safety member cooperate to align and seat the elastic member 310R between the second portion 21.IB of the housing 210 and the safety feature 310 to deflect the safety feature 310 to a retaining position.

[0085] In this embodiment, the housing 210B also comprises a tab 210T near an outer periphery that can cooperate with a groove construction 21GG in the first portion 210A of the housing 210 to align and / or seal the device. The interface between the housing components may have another structure or feature to secure or seal the components, such as fasteners to secure the housing components or an adhesive, gasket, or common or solderable feature for sealing. The 210 housings can have any suitable shape, design, or configuration as desired. The 210 housings may comprise at least one 210S rib or bracket, thereby providing crush support for the 200 extension port and resulting in a robust structure. Furthermore, the 210 housings may comprise more than two portions if desired. Likewise, multiple portions of the 210 housing may comprise 236 connection ports.

[0036] Any of the extension ports 200 described herein may optionally be weatherproofed by appropriately sealing the housing seams 210 between the components using any suitable means, such as gaskets, O-rings, adhesive, sealant, welding, overmolding, or the like. In addition, the interface between the connection ports 236 and the dust cover or connector 10 may be sealed using appropriate geometry and / or a sealing element such as an O-ring or gasket 65 on the connector or dust cover. If the extension port 200 is intended for indoor applications, then weatherproofing may not be required. [u08z] The 200 extension port may also include integrated mounting features. For example, the 210 housing may have mounting features configured as pass-through zones on the side edges. Therefore, the user can simply use a fastener such as a zipper threaded through these side pass-through zones to mount the 200 extension port on a wall or pole, as desired. As shown in FIGURE 9, the coupling plane 230MP of the connector between the ferrules 10F of the connectors 10 is arranged within the cavity 216 of the extension port 200. The connectors 10 include a locking feature 20L in the housing 20 to cooperate with a safety feature 310 of the extension port 200. In addition, the connection ports 236, 236' comprise a suitable length L between the locking features 3-iu associated with the connection ports 236, 236' so that the connectors 10 can have the appropriate amount of float for proper optical performance. The connector 10 may comprise at least one O-ring 65 for sealing with the area d.The connector port passage 233 has a sealing surface 233SS when the connector 10 is fully inserted into the connection port 236. Illustratively, the connection port 236 has a sealing surface 233CS for the connection port passage area for the connector 10, positioned at a distance D3 from the mating plane 230MP of the connectors 10. A distance D3 is farther from the mating plane 230MP than the Plaquea feature 310L of the locking feature 310. The component tolerance buildup between the locking features 310L at distance L must be managed to allow a proper connector-to-connector interface with the mating ferrules 5.

[0089] FIGURES 10-12 represent detailed perspective views of the 310 safety feature shown by the explanatory device in FIGURE 1. The 310L locking feature comprises a 310RS Lj retaining surface. In this embodiment, the rear side of the ramp of the 310L locking feature forms a projection that cooperates with the complementary geometry in the connector housing 20 of the connector 10. However, the 310RS retaining surface may have different surfaces, or edges that cooperate to secure the connector 10 by creating the desired mechanical retention. For example, the 310RS retaining surface may be sloped or have a vertical wall to adapt the pull-out force for the connection port 236. However, other geometries are possible for the 2.0 Retention surface 310RS. Additionally, the connection port 236 has a sealing location on a sealing surface of the connection port passage zone with connector 10 that is located closer to the optical connector opening 238 on the outer surface 234 than the safety feature 310 or the locking feature 3.10L.

[0090] The 310 safety feature may also comprise other features best represented in FIGURES 10-12. For example, the 310 safety feature may include a 310S sealing member disposed over the 233 pass-through area of ​​the connector port to keep dirt, debris, and the like out of the 200 extension portions of the port. The 310S sealing member is sized for the 310RG retaining groove in the 310 safety feature and the 245 pass-through area of ​​the safety feature for sealing. [0u91] The 310 safety feature may also comprise one or more 310G guides cooperating with the housing to maintain the 310B hole in the proper rotational orientation within the passage zone 245 of the respective safety feature during translation. In this embodiment, two 310G guides are arranged approximately 180 degrees apart and guide the translation of the 310 safety feature. The 310 safety feature may also comprise one or more 310K encoders cooperating with the housing 210 or the connection port insert 230 to permit only one assembly orientation within the housing 210 or the connection port insert 230, thereby maintaining the 310L locking feature in the proper position within the passage zone 245 of the respective safety feature with respect to the direction of connector insertion. (.0-O92] The 310 security feature may also comprise a 310SS top surface to inhibit over-displacement or removal of the 310 security feature from the 200 extension port during assembly. In this embodiment, the 310SS top surface is arranged as the top surface of the 310G guides. The 310 security feature may also include a 310G dimple or other feature to inhibit inadvertent activation / translation of the 310 security feature or to provide a tactile feel to the user. The 310 security feature may also be a different color or have identification markings to identify the port type. Ί5

[0093] As best shown in FIGURES 10 and 11, the locking feature 310L is configured as a ramp 3-10'RP running to a short flat portion, then to a projection reverting to a round cross-section to create the retaining surface 310RS to engage and retain the connector 10 once it is fully inserted within the pass-through zone 233 of the connector port 236. Accordingly, the safety feature 310 is able to move to an open (OP) position when a suitable connector 10 is inserted within the pass-through zone 233 of the connector port, as the connector housing 20 engages the ramp 310RP by pushing the safety feature down during insertion.

[0094] Safety feature 310 moves from a holding (RP) position to an open (OP) position S is correctly positioned when a suitable connector 10 is inserted into the connection port 236. Once the connector 10 is fully inserted into the connector's passage area 233, the safety feature 310 automatically moves to the retaining (RP) position as it is biased upwards. This advantageously allows plug-and-play connectivity of the connectors 10 with the extension port 200 without having to turn a coupling nut or bayonet as with conventional devices. Therefore, connections to the extension port 15 can be made more quickly and in positions that might be awkward with relative ease. [00951 Still other types of 310 safety members may function similarly to secure the connector 10, but comprise more than one component such as an actuator 20 310A cooperating with a 310M safety member as described herein in other modalities, additionally, the use of more than one component may permit other arrangements for the passage zone .245 of the safety feature with respect to a longitudinal axis LA of the device. 25

[0096] To make identification of connection ports easier for the user, a marking clue can be used such as text or color code on the extension door or marking the entry strap (e.g., an orange or green polymer) or similar. 1009'7 J Any of the extension ports 200 may also have one or more dust caps (not shown) to protect the connection port 236 from dust, dirt, or debris entering the extension port or interfering with optical performance. Therefore, when the user wishes to make an optical connection to the extension port, the appropriate dust cap is removed, and then the connector 10 of the cable assembly 100 can be inserted into the respective connection port 236 to make an optical connection to the extension port 200. Dust caps may use release and retention features similar to those of 10 connectors. For example, when the 310 safety feature is pushed in or down, the dust cap is released and can be removed.

[0098] Other variations of the 200 extension ports are possible according to the concepts described. For example, the 200 extension ports in FIGURES 13-18 and 18-24 are similar to the 200 extension port in FIGURE 1, except that they use different mechanisms with the 310 security feature. FIGURES 13-17 show another illustrative fiber optic 200 extension port according to the concepts described. The 200 extension port in FIGURES 13-17 is similar to the 200 extension port in FIGURE 1, except that it uses a single 310M security member that has opposing 310L locking features. Using two 3101 locking features on a common 310M safety member datum of FIGURE 13 provides easier control of the length L between the 310L locking features compared to tolerance build-up of the r:..Multiple individual actuator components 310A (i.e., two) cooperate with the safety member 310M to release and engage the connection ports 236. Like the extension port 200 in FIGURE 1, the spring members 310R tilt the safety member 310M upward to a retaining position at each end for the respective connection ports 236, thus providing a normally locked position for the connection port 236. To release the locking feature 310L of the safety member 310M in FIGURE 13, either of the actuators... 310A can be pushed down to move one end of the safety member 310M downwards and move the locking feature 310L to a release position. {0099] FIGURES: 13 and 14 represent partially exploded views of the 200 extension port that .25 shows construction details, and FIGURE 15 shows an assembled view with the second portion 21.0B removed. The 200 extension port has diverted safety features that function similarly to the other extension ports described. However, this extension port uses a 310 safety feature with a common 310M safety member comprising two 310L locking features to prevent the accumulation of tolerances from multiple components in the device, thus helping to preserve optical performance. With reference to Figure 13, the two 310L locking features on the common 310M safety member are positioned at the desired distance L to allow for proper connector-to-connector interfacing between mating ferrules; the ferrule tolerances and travel of the connectors can also be considered. The opposing 310L locking features are molded into a common 310M safety member as depicted in Figures 13-16.The 310L locking features of the common 310M safety member may have a geometry suitable for securing connectors such as 20 as described in this document. The actuator 310A cooperates with the respective safety feature 245 passage zone formed as a portion of the first portion 210A of the housing 210 as discussed in this document. The actuators 310A also comprise the push arms 310A which are separated to allow a portion of the connector 10 to pass through them for coupling as shown in FIGURE 16. When assembled, push the contact portions of the 310PA arms of the safety member 31OM adjacent to the 5 locking feature as shown and move the 310A actuator downwards, moving the 310.L locking feature to a release position.

[00101] Just like the port 200 extension of the FIGURE 1. The safety feature 310 can be moved in a vertical direction, as represented by the arrows in FIGURE 16, to retain and release the connector in the extension port 200. As shown, the spring members 310R are arranged below the safety member 310M to press the ends of the safety member 310M (and the actuators 310A) upward to a normally retained position (RP). The safety feature 310 further includes a locking feature 310L.

[00102] A simplified adapter assembly 230A is used in this embodiment, comprising a ferrule sleeve 230FS 20 for the precision alignment of mating ferrules between connectors 10, which is disposed within the adapter's OH housing 23 without a spring member. FIGURE 17 represents the fully assembled 200 extension port.

[00103] Devices may have other constructions for the 310 security feature that use more than one component. Illustratively, FIGURES 18-24 represent another extension port 200 comprising a connection port 236 as a portion of the housing 210 with the 310 security feature comprising more than one component. This extension port is similar to the construction described, and the description of this device with the 310 security feature comprising more than one component will describe the differences in design for the sake of brevity, and other features are similar to those described.

[00104] The extension port 200 of FIGURES 18-24 utilizes safety feature 310 comprising an actuator 310.A and a safety feature member 310M. Specifically, the safety feature member 310M, comprising an opening that can be elastically deformed by the actuator 310A (or other structure) when it is pushed (or after the insertion of a suitable connector 10 into the connection port 236), and the safety feature member 310M springs back to engage a suitable portion of the connector 10, such as the locking feature 20L of the connector 20, when the actuator 310.A is released or when the connector 10 is fully seated within the connection port 236, as will be discussed in more detail. As best shown in FIGURE 29, the 310M safety member comprising a 31QL locking feature formed by one or more 310AM arms.

[00105] Figures 19-22 are partial assembled views with portions of a 310SA safety feature subassembly removed, as discussed below, to reveal the construction and operation of the 310 safety feature. As depicted in Figure 19, the 310M safety member can be placed within a housing formed by one or more 310HH housing portions to maintain the proper orientation of the safety feature within the 210 housing. The 310SA safety feature subassembly also allows for easier assembly of 310M safety members within the 210 housing of the 200 extension ports. In other words, the 310HH housing portions can have a geometry suitable for maintaining the safety members in the desired orientation.The right side of FIGURE 19 represents the safety feature sub-assembly 310SA assembled and positioned within the second portion 210B of the housing 210. For example, the second portion 210B may have a pocket or other alignment feature to seat the safety feature sub-assembly 310SA. The left side of FIGURE 19 represents the safety member 310M and actuator 310A without the housing portions 310HH to show the engagement with the locking features at connector 10. Accordingly, the actuators 31OA are aligned and positioned with the respective safety member 310M of the safety features. [Γ00106] FIGURE 20 is a detailed perspective view showing the safety member 3ION disposed within the components 310H of 310SA and the adapter assembly 23OA removed to show the mating of complementary ferrules 10F 10 of the connectors 1Q. Specifically, the arms of the safety member 310M mate with a locking feature 20L (e.g., a slot) that is integrally formed in the connector housing 20. FIGURE 21 is a similar detailed perspective view to FIGURE 20, but shows the adapter assembly 230A. (00107j The safety feature 310 comprising the actuator 310A and the safety member 310M. The safety member 310M comprising an opening between its arms 310AM that can be elastically deformed by the actuator 310A when it is moved (i.e., pushed) or after the insertion of a suitable connector 10 into the connection port 236 by extending (i.e., moving) the arms of the safety member 310M outward. When the actuator 310A is released or the connector is fully seated within the connection port 236 or the inlet port 260, the arms 310AM of the safety member 310M spring back to engage a suitable portion of the connector 10, such as the locking feature 20L of the connector housing 20, or move the actuator 310A to a normal position. The arms 3.1 OAM have a rim portion that acts as a 3.10L locking feature for the appropriate connector 10.For clarification, the edge portions of the 310AM arms engage with the 20L locking feature of the 20 connector housing to secure the 20 connector. In order to release the 10 connector from the 236 connection port, the 310AM arms and the 310L locking features on the 310AM arms are moved outward.

[00108] As best shown in FIGURE 27, the actuator 310A comprises a cradle 31QW that pushes into the end 3'1 OH of the safety member head 310M, thereby elastically deflecting the member arms 310AM 310.M safety member outward to release connector 10. The 310A safety member or the actuator of the 310 safety feature may comprise a variety of different constructions. Similarly, 310 safety features comprising more than one component may be deflected by a 310RM elastic member of the safety feature if desired. For example, the 310RM elastic member of the safety feature may deflect the 310A actuator to a safe position. In other embodiments, the elastic member of the safety feature may deflect the 310M safety member. [0'0109] FIGURES 25-27 are various perspective views of the 310.A actuator of the 310 safety feature of the 200 extension port shown in FIGURES 18-24. The 310A actuator may include a 310S sealing member disposed above the 233 pass-through area of ​​the connector port to keep dirt, debris, and the like out of the 200 extension port portions. The 310S sealing member is sized for the 310RG retaining groove on the 310A actuator and the 245 pass-through area of ​​the safety feature for sealing. The actuator 31'0A can also be configured to have one or more guides 310G that cooperate with the housing 210 or the insert 230 of the connection port to maintain the proper rotational orientation of the wedge 310W within the passage zone 24 5 of the respective safety feature during translation. In this configuration, the shape of the flange assists in the rotational orientation.The 31 DA actuator may also include a 310.SS upper surface to inhibit overtravel or the 310A actuator from being pulled back from the 200 extension port when assembled. The 310A actuator may also be a different color or have identification markings to identify the port type. For example, the 31QA actuator may be red for the 236 connection ports, and the 31OA actuator for the 260 input connection port may be black. Other colors and markings may be used for pass-through ports, multi-fiber ports, or split-signal ports. L0-01 lOj Therefore, the security feature member 3.10M of the security feature 310 is suitable for retaining the connector 10 within the connection port 236 10 as discussed herein. Several different modes are possible for securing the security features 310 comprising more than one component for the devices described. Figures 25-29 are various views of the 310M safety member to explain the design details. Figure 28 is a perspective view of the blank safety member forming the 310M safety feature depicted in Figure 29. The 310M safety member can be formed from any suitable material, such as spring steel, and have a geometry suitable for retaining a connector. As shown, the 310M safety member comprises arms defining an opening (unnumbered) between the arms, along with a head end formed at the ends of the arms. The opening (unnumbered) between the arms is dimensioned to cooperate with a suitable connector. The 310AM arms may comprise 310T tabs that are curved to assist the coupling of the 10 connector with the 310M safety member after insertion and to allow smoother pushing and translation of the 3 arms.10AM facing outwards when connector 10 is inserted into port 236. Similarly, the end. The OH head can also be formed with a suitable shape that cooperates with the 310A actuator. Like the other 310 safety features, the 310 safety feature can comprise more than one component for translation from a retained (RP) position to an open (OP) position as a suitable connector 10 is inserted into the connection port 236. Once the connector 10 is fully inserted within the 15 step zone 233 of the connector, the 310 safety feature then automatically moves to the retained (RP) position as the 3.10AM arms are deflected to the retained position.
