Description

Technology Field

[0001] The present disclosure relates to an optical transceiver and an active optical cable (AOC) using the same, and more specifically, to an optical transceiver and an active optical cable using the same that includes a plurality of optical fiber cables and is designed in a modular form to facilitate assembly and repair. Background Technology

[0002] An active optical cable (or active optical cable) is formed by connecting a fiber optic cable and optical transceivers located at both ends of the cable to form a single component assembly. The optical transceiver provides optoelectric conversion and optical transmission functions, offering compatibility with standard electrical interfaces while simultaneously improving transmission speed and transmission distance using the optical cable. For example, the optical transceiver may include standard electrical interfaces such as GBIC (Gigabit Interface Converter), SPF (Small Form-factor Pluggable), SPF+, XFP, QSPF, QSFP+, QSFP28, and CFP.

[0003] Active optical cables are primarily used to connect switches, servers, and storage within data centers, and are also utilized for high-speed, high-capacity data transmission in servers, high-performance computers, large-capacity storage, and high-resolution displays. Compared to Direct Attach Cables (DACs) or Active Copper Cables (ACCs) that use copper wires, active optical cables have the advantages of being lightweight, having long transmission distances, being easy to wire, and being resistant to electromagnetic interference.

[0004] However, active optical cables are more expensive than DACs and ACCs due to the optical transceivers. Furthermore, since existing active optical cables are implemented as single-component assemblies, there is a problem in that the entire active optical cable must be replaced even if only some of the constituent components are damaged. For example, if the optical fiber is damaged, the connection between the optical fiber and one optical transceiver is damaged, or only one optical transceiver is damaged, the entire active optical cable must be replaced with a new product.

[0005] In addition, conventional active optical cables have the problem of a complex manufacturing process and increased costs because precise optical alignment is required between the optical components inside the optical transceiver and the optical fiber during the manufacturing process of combining the optical fiber and the optical transceiver.

[0006] Furthermore, active optical cables containing multiple optical cables are required to increase the transmission capacity of active optical cables, but there are problems such as complex assembly and repair, and difficulty in optical alignment during the process of connecting multiple optical cables to an optical transceiver.

[0007] Ultimately, there was a demand for a modular active optical cable that includes multiple optical fiber cables and is easy to assemble and repair, but there was a problem in that this could not be provided according to conventional technology, and the present disclosure is intended to solve this problem. The problem to be solved

[0008] The present disclosure is intended to provide a modular active optical cable.

[0009] The present disclosure is intended to provide a modular active optical cable comprising a plurality of optical fiber cables.

Specific details for implementing the invention

[0036] To clarify the technical concept of the present disclosure, embodiments of the present disclosure will be described in detail with reference to the attached drawings. In describing the present disclosure, detailed descriptions of related known functions or components will be omitted if it is determined that such detailed descriptions would unnecessarily obscure the essence of the present disclosure. Components having substantially the same functional configuration among the drawings have been assigned the same reference numerals and symbols as much as possible, even if they are shown in different drawings. For convenience of explanation, devices and methods will be described together where necessary. Each operation of the present disclosure does not necessarily have to be performed in the order described and may be performed in parallel, selectively, or individually.

[0037] The terms used in the embodiments of this disclosure have been selected to be as widely used and general as possible, taking into account the functions of this disclosure; however, these terms may vary depending on the intent of those skilled in the art, case law, the emergence of new technologies, etc. Additionally, in specific cases, terms have been selected at the applicant's discretion, and in such cases, their meanings will be described in detail in the description of the relevant embodiments. Therefore, terms used in this specification should be defined not merely by their names, but based on their meanings and the overall content of this disclosure.

[0038] Throughout this disclosure, singular expressions may include plural expressions unless the context clearly indicates otherwise. Terms such as “comprising” or “having” are intended to specify the presence of features, numbers, steps, actions, components, parts, or combinations thereof, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. That is, throughout this disclosure, when a part is described as “comprising” a certain component, it means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0039] Expressions such as "at least one" modify the entire list of components and do not modify the components of the list individually. For example, "at least one of A, B, and C" and "at least one of A, B, or C" refer to only A, only B, only C, both A and B, both B and C, both A and C, all of A, B, and C, or any combination thereof.

[0040] Additionally, terms such as “...part,” “...module,” etc., as described in this disclosure refer to a unit that processes at least one function or operation, and may be implemented in hardware or software, or a combination of hardware and software.

[0041] Throughout the entire disclosure, when a part is described as being “connected” to another part, this includes not only cases where they are “directly connected” but also cases where they are “electrically connected” with other elements interposed between them. Furthermore, when a part is described as “comprising” a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0042] As used throughout this disclosure, the expression “configured to” may be replaced, depending on the context, with, for example, “suitable for,” “having the capacity to,” “designed to,” “adapted to,” “made to,” or “capable of.” The term “configured to” may not necessarily mean only “specifically designed to” in hardware. Instead, in some situations, the expression “system configured to” may mean that the system is “capable of” together with other devices or components. For example, the phrase “a processor configured (or set) to perform A, B, and C” may mean a dedicated processor for performing said operations (e.g., an embedded processor), or a generic-purpose processor (e.g., a CPU or an application processor) capable of performing said operations by executing one or more software programs stored in memory.

[0043] Throughout this disclosure, terms including ordinal numbers, such as “first,” “second,” etc., may be used to describe various components, but the components are not limited by the terms. The terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of this disclosure, the first component may be named the second component, and similarly, the second component may be named the first component. The term “and / or” includes a combination of multiple related items or any one of the multiple related items.

[0044] The present disclosure relates to an active optical cable (AOC), and more specifically, to an active optical cable designed to be modular, making assembly and repair easy.

[0045] FIG. 1 is a conceptual diagram illustrating the structure of an active optical cable according to one embodiment of the present disclosure.

[0046] Referring to FIG. 1, an active optical cable (AOC) according to one embodiment of the present disclosure may include an optical fiber cable (20) and optical transceivers (10) at both ends thereof. In one embodiment, the optical transceiver (10) may include an optical source (16) that generates an optical signal and a driving unit (17) that controls the optical source (16) to convert a received electrical signal into an optical signal. For example, the optical source (16) may be composed of a laser diode or a VCSEL (Vertical Cavity Surface Emitting Laser), and the driving unit (17) may be composed of a transmitting IC such as a laser driver. In one embodiment, the optical transceiver (10) may include an optical receiver (11) that receives an optical signal and converts it into an electrical signal, and a signal processing unit (12) that processes the converted electrical signal. For example, the optical receiver (11) may be composed of a photodiode, and the signal processing unit (12) may perform operations such as signal amplification, noise removal, and signal format conversion on the electrical signal output from the optical receiver (11).

[0047] Referring to FIG. 1, an active optical cable (AOC) according to one embodiment of the present disclosure may include an interface section (15), and the interface section (15) may be configured according to a standard electrical interface. For example, the interface section (15) may be configured according to a standard electrical interface such as a GBIC (Gigabit Interface Converter), SPF (Small Form-factor Pluggable), SPF+, XFP, QSPF, QSFP+, QSFP28, CFP, etc.

[0048] FIG. 2 is a configuration diagram illustrating the external structure of an active optical cable according to one embodiment of the present disclosure.

[0049] Referring to FIG. 2, an active optical cable according to one embodiment of the present disclosure may include an optical cable module (100) and a first optical transceiver module (200). In one embodiment, the optical cable module (100) may include an optical cable (110) and a connector portion (120, connector). In one embodiment, the first optical transceiver module (200) may include an insertion port (210), an interface portion (220), and a handle portion (230).

[0050] According to one embodiment of the present disclosure, the interface unit (220) is configured with a standard electrical interface and can be electrically connected to another computing device (not shown). For example, the interface unit (220) may be configured according to a standard electrical interface such as GBIC (Gigabit Interface Converter), SPF (Small Form-factor Pluggable), SPF+, XFP, QSPF, QSFP+, QSFP28, CFP, etc.

[0051] According to one embodiment of the present disclosure, when the connector portion (120) of the optical cable module (100) is inserted through the insertion port (210) of the first optical transceiver module (200), the connector portion (120) of the optical cable module (100) is coupled inside the first optical transceiver module (200), and the optical fiber of the optical cable (110) and the optical component of the first optical transceiver module (200) can be optically aligned. For example, the first optical transceiver module (200) and the connector portion (120) can be coupled in a structure that is not easy to separate without repair equipment, by using interlocking protrusions, latch structures, etc., to form an active optical cable (AOC). Referring to FIG. 2, the first optical transceiver module (200) and the connector part (120) are joined through a latch structure (221) and do not include a separate configuration for separation (e.g., a release tap, etc.), so they can be used as a single component active optical cable (AOC).

[0052] According to one embodiment, a single-mode optical fiber or a multi-mode optical fiber may be used in the optical cable module (100) and the first optical transceiver module (200). For example, a multi-mode optical fiber may be used with a VCSEL light source, or a single-mode optical fiber may be adopted together with a more precise laser light source. Ultimately, one embodiment of the present disclosure may also be applicable in cases including a single-mode type optical transceiver.

[0053] According to one embodiment, the handle portion (230) is intended to pull the active optical cable (AOC) connected to the computing device through the interface portion (220) to detach it from the computing device. Using the handle portion (230) has the effect of avoiding damage to the optical cable (110) or the first optical transceiver module (200) during the process of detaching the active optical cable. In one embodiment, the optical cable (110) may include an optical fiber and a sheath that protects the optical fiber.

[0054] FIG. 3 is a schematic diagram illustrating the external structure of an active optical cable according to another embodiment of the present disclosure.

[0055] Referring to FIG. 3, an active optical cable according to one embodiment of the present disclosure may include a plurality of optical cable modules (100) and a second optical transceiver module (300) capable of combining them. In one embodiment, the second optical transceiver module (300) is provided with a plurality of insertion ports (310) so that an optical cable module (100) can be combined to each insertion port (310). Consequently, as many optical cable modules (100) as there are insertion ports (310) provided by the second optical transceiver module (300) can be combined. FIG. 3 illustrates a second optical transceiver module (300) capable of combining two optical cable modules (100), but the number of insertion ports (310) that the second optical transceiver module (300) may include may exceed two, and is not limited to the embodiment of FIG. 3. In one embodiment, the second optical transceiver module (300) may include an interface section (320) composed of a standard electrical interface. The specific configuration of the second optical transceiver module (300) will be described in more detail later.

[0056] FIG. 4 is a configuration diagram illustrating the external structure of an optical cable adapter and an optical cable module coupled thereto according to another embodiment of the present disclosure.

[0057] Referring to FIG. 4, an optical cable adapter (400) according to one embodiment of the present disclosure can extend an optical cable by combining two optical cable modules (100). In one embodiment, the optical cable adapter (400) may include an insertion port (410) and a cable latch groove (420) at both ends. Two optical cable modules (100) are each inserted into the insertion ports (410) located at both ends of the optical cable adapter (400), and the latch (125) of each optical cable module (100) can be coupled to and fixed in the cable latch groove (420). During the process of combining the two optical cable modules (100) to the optical cable adapter (400), the optical paths of the two optical cable modules (100) are connected to each other, so that the two optical cable modules (100) can be optically connected. The optical cable adapter (400) and its coupling structure will be described in detail later.

[0058] FIGS. 5 to 9 are configuration diagrams illustrating the coupling structure of an optical connector (500) for optical coupling according to one embodiment of the present disclosure.

[0059] As previously described, the optical cable module (100), the first optical transceiver module (200), and the second optical transceiver module (300) each include an optical connector (500) for optical coupling, and during the process of combining the two modules, the optical connectors (500) of each module can be optically coupled to each other to form an optical path.

[0060] According to one embodiment, each optical connector (500) is connected to an optical cable (110), and the optical connectors (500) may include a structure capable of being physically coupled to each other. For example, the optical connectors (500) may include protrusions and indentations capable of being coupled to each other, and the two can be coupled by coupling the uneven surfaces of the optical connectors (500). According to one embodiment, the optical connectors (500) may include a structure capable of forming an optical path by optical coupling during the process of physically coupling to each other. For example, during the process of coupling the uneven surfaces of the optical connectors (500), an optical path capable of transmitting and receiving optical signals between two optical connectors (500) can be configured to be aligned.

[0061] Referring to FIGS. 5, 6, 8, and 9, two optical connectors (500) can be joined together by aligning them in opposite directions and then bringing the coupling grooves (551) formed on their bottom surfaces into contact with each other. In one embodiment, the two optical connectors (500) can be joined by pushing them in opposite directions while parts of the coupling grooves (551) are in contact with each other, and at this time, they can be joined at the correct position by means of guide portions (554) formed on the two optical connectors (500). Referring to FIG. 5, the guide portion (554) has an inclined surface in the direction of pushing the optical connector portions (500) to join them, and a part of it may be formed with a different incline so that it is no longer pushed when the two optical connectors (500) are completely joined. For example, the guide portion (554) may be formed with a constant inclined surface and a vertical surface as shown in FIG. 5. In one embodiment, two optical connectors (500) can be naturally joined together along the guide portion (554) by pushing forces in opposite directions.

[0062] In one embodiment, the optical connector (500) is located inside the optical cable module (100), the first optical transceiver module (200), or the second optical transceiver module (300), and during the process of these modules being coupled to each other, the optical connectors (500) inside are also coupled to each other. For example, when the optical cable module (100) is inserted into the insertion port (210, 310) of the first optical transceiver module (200) or the second optical transceiver module (300), or when two optical cable modules (100) are inserted into the two insertion ports (410) of the optical adapter (400), they are coupled by a force pushing in opposite directions.

[0063] In one embodiment, an optical path between two optical connectors (500) can be formed through a coupling groove (551) on the bottom surface. For example, an optical path between two optical connectors (500) can be formed through a lens (555) located in the coupling groove (551). That is, when two optical connectors (500) are coupled together, the lenses (555) of the two optical connectors (500) can be fixed in positions facing each other.

[0064] Referring to FIGS. 5, 7 and 9, the coupling projection (552) of the optical connector (500) is formed to face the front side portion (553) of another optical connector (500), so that the two optical connectors (500) can be joined in close contact with each other during the joining process. In one embodiment, the coupling projection (552) of the optical connector (500) is formed as an inclined surface at a certain angle (with respect to the vertical direction), and the front side portion (553) of the optical connector (500) is also formed as an inclined surface at the same angle in the opposite direction (with respect to the vertical direction), so that they can be joined along the inclined surface as in FIG. 6(c). Since the coupling projection (552) and the front side portion (553) of the optical connector (500) have slopes (gradients) in opposite directions, when the two optical connectors (500) are coupled with each other with the slopes, they can be accurately aligned and prevented from separating from each other and can also prevent left-right shaking.

[0065] Referring to FIGS. 5 and 8, an optical connector (500) according to one embodiment may include a cover portion (510) and a body portion (550), and the cover portion (510) and the body portion (550) may be combined to form the optical connector (500). According to one embodiment, the optical fiber (20) of the optical cable (110) is seated on the optical fiber guide (557) of the body portion (550), and the optical fiber (20) may be fixed inside the cover portion (510) as it is coupled to the body portion (550). According to one embodiment, the optical fiber (20) of the optical cable (110) may be protected by a covering.

[0066] According to one embodiment, the cover portion (510) includes one or more cover protrusions (511), and the cover protrusions (511) are each coupled to the body groove (560) of the body portion (550), so that the cover portion (510) and the body portion (550) can be assembled. According to one embodiment, the body portion (550) may include a groove having the same shape as at least a part of the outer surface of the cover portion (510), and the cover portion (510) may be seated in the groove of the body portion (550) to be coupled to each other. In order for the cover portion (510) to be securely fixed to the body portion (550), the gap between the inner surface of the groove of the body portion (550) and the outer surface of the cover portion (510) may be formed narrowly to be suitable for snap-fit ​​coupling. In one embodiment, a part of the inner surface of the groove of the body portion (550) may be formed to have a relatively wide gap with the outer surface of the cover portion (510). For example, referring to FIG. 5, a portion of the inner surface of the groove of the body part (550) may form a gap groove (558), and by using the gap groove (558) formed in the body part (550), the cover part (510) can be easily separated from the body part (550).

[0067] According to one embodiment, the cover portion (510) may include an open groove (512) formed through the cover portion (510). When the cover portion (510) is combined with the body portion (550), the open groove (512) is positioned on the optical fiber guide (557) on which the optical fiber (20) is seated, and may be configured to allow a liquid substance to be introduced into the optical fiber (20) through the open groove (512). According to one embodiment, the liquid substance introduced through the open groove (512) may fix at least one optical fiber (20) introduced via the optical fiber guide (557) or improve the efficiency of optical coupling. For example, the liquid introduced through the open groove (512) may be epoxy or a refractive index matching material, and through a fixing process utilizing these, contamination that may occur on the cross-section of at least one optical fiber (20) can be blocked, and the difference in refractive index between the cross-section of at least one optical fiber (20) and the optical boundary surface (559) can be minimized to reduce Fresnel reflection loss. By utilizing this process, an optical transceiver assembly according to one embodiment of the present invention can maximize the efficiency of optical coupling.

[0068] FIG. 10 is a top and bottom perspective view of a body portion constituting an optical connector according to one embodiment of the present disclosure.

[0069] Referring to FIG. 10, the cross-section of the optical fiber (20) placed on the optical fiber guide (557) faces the optical boundary surface (559) of the body part (550), and light emitted through the optical fiber (20) is incident through the optical boundary surface (559). Additionally, the reflector (556) can change the direction of travel so that the light incident through the optical boundary surface (559) is reflected and emitted through the lens (555) on the lower surface of the body part (550). In one embodiment, the reflector (556) may selectively apply a reflection coating depending on whether the total reflection (TR) or internal total reflection (TIR) ​​condition is satisfied.

[0070] Referring to FIG. 10, light emitted from an optical fiber (20) mounted on an optical fiber guide (557) passes through an optical boundary surface (559) and travels in the y-axis direction (+y), is reflected from a reflector (556) to travel in the z-axis direction (-z), and can be emitted through a lens (555) on the lower surface of a body part (550). In one embodiment, when two optical connectors (500) are combined, each lens (555) is fixed in a position facing each other, so light emitted through the lens (555) of one optical connector (500) is incident on the other optical connector (500) through the lens (555), is reflected from the reflector (556) of the other optical connector (500) in the direction of the optical fiber (20) (+y-axis direction), passes through the optical boundary surface (559), and is incident on the optical fiber (20).

[0071] In one embodiment, the reflector (556) performs a collimating function that changes the direction of light propagation and converts all or part of the light into light traveling parallel to each other, and may be referred to as a parallel mirror, collimating mirror, collimating mirror, collimating mirror, collimating mirror, etc. For example, the reflector (556) may be composed of a prism that reflects light using the difference in refractive index between air and the medium. Referring to FIG. 10, the reflector (556) may be composed using a groove for forming a reflective prism. Also, in one embodiment, the lens (555) performs a collimating function that converts all or part of the passing light into light traveling parallel to each other, and may be referred to as a parallel lens, collimating lens, collimating lens, etc.

[0072] FIG. 11 is a conceptual diagram illustrating an optical path after the mutual coupling of optical connectors (500) according to one embodiment of the present disclosure.

[0073] According to one embodiment of the present disclosure, in optical connectors (500), the optical fiber (20) is seated on the optical fiber guide (557) and then faces the optical boundary surface (559). Light emitted from the optical fiber (20) of the first optical connector (500) is incident through the optical boundary surface (559), and its direction of travel is changed at the reflector (556) of the first optical connector (500) and travels to the lens (555). When the first optical connector (500) and the second optical connector (500) are combined, the lens (555) of the first optical connector (500) faces the lens (555) of the second optical connector (500). Therefore, light traveling through the lens (555) of the first optical connector (500) enters the lens (555) of the second optical connector (500), and the direction of travel is changed at the reflector (556) of the second optical connector (500) and enters the optical fiber (20) connected to the second optical connector (500) through the optical boundary surface (559) of the second optical connector (500).

[0074] According to one embodiment, the reflection angle of the reflector (556) may be formed to be 90 degrees. Here, the reflection angle may be defined as the angle between the optical axis of light incident on the reflector (556) and the direction of travel of parallel beams reflected by the reflector (556). According to another embodiment, the reflection angle of the reflector (556) may be formed to be less than or greater than 90.

[0075] According to one embodiment, the lenses (555) of the first optical connector (500) and the second optical connector (500) may face each other with an air gap of less than 0.1 mm between them. Additionally, an anti-reflection coating may be formed on the surfaces of the lenses (555) of the first optical connector (500) and the second optical connector (500).

[0076] Figure 12 is a conceptual diagram illustrating the shape of a light beam by a cylindrical lens.

[0077] According to one embodiment, a cylindrical lens (or cylindrical lens) may be used as a reflector (556) and a lens (555). When the cylindrical lens is positioned vertically and light emitted from and diffused by the optical fiber (20) passes through the cylindrical lens, it performs the function of collimating the direction of light propagation in the horizontal direction without changing the direction of light propagation in the vertical direction. Referring to FIG. 12, for a cylindrical lens positioned in the y-axis direction (vertical direction) and having a cross-section formed as an arc in the z-axis direction (direction of light propagation), when light is emitted from the optical fiber positioned in the z-axis direction and passes through the cylindrical lens, the light is collimated in the x-axis direction (horizontal direction) and no longer diffuses, but the light continues to diffuse in the y-axis direction (vertical direction).

[0078] FIG. 13 is a conceptual diagram illustrating the propagation of light when the reflector and the lens are cylindrical lenses according to one embodiment of the present disclosure.

[0079] In one embodiment, cylindrical lenses may be adopted as the reflector (556) and the lens (555). Referring to FIG. 10, the reflector (556) may be formed as a separate cylindrical lens for each optical fiber (20), and the lens (555) may be formed as a single cylindrical lens. Referring to FIG. 13, light emitted from the optical fiber (20) positioned in the z-axis direction passes through the light boundary surface (559) and reaches the reflector (556), and the direction of propagation of the light is changed at the reflector (556) (changed from the z-axis direction to the -y-axis direction in FIG. 13) and directed toward the lens (555). The reflector (556) is composed of a cylindrical lens and reflects light, and the light is collimated in the horizontal direction (x-axis direction) of the cylindrical lens that is the reflector (556) to become parallel light, and the light continues to radiate in the vertical direction (y-axis direction) of the cylindrical lens.

[0080] In one embodiment, light reaching the cylindrical lens (555) passes through the lens (555) and is collimated in the horizontal direction (z-axis direction) of the cylindrical lens to become parallel light. The lens (555) does not change the direction of light propagation in the vertical direction (x-axis direction) of the cylindrical lens, but the vertical direction (x-axis direction) of the cylindrical lens is already collimated by the cylindrical lens reflector (556) and consists of parallel light. Consequently, the light passing through the cylindrical lens (555) is collimated in all directions and emitted as perfectly parallel light.

[0081] According to one embodiment, when light emitted from an optical fiber (20) is collimated in the x-axis direction by a reflector (556), optical crosstalk does not occur between channels in the x-axis direction. Since the light emitted from the optical fiber (20) is not constrained by optical interference in the y-axis direction, it reaches the lens (555) on the bottom surface in a diverging state without being collimated by the reflector (556). The light that reaches the lens (555) on the bottom surface travels parallel in the x-axis direction and continues to diverge in the z-axis direction (since the direction of the light is changed by the reflector), becoming an optical beam in the shape of an ellipse with a larger diameter in the z-axis direction, and the beam size is formed to be relatively larger than in the case where the light is collimated in all directions by the reflector (556). As a result, since it has a large beam size, the effect of the light signal being affected by dust particles, etc. is further reduced. In addition, to aim light in all directions, the complexity of mold processing for processing the reflector (556) into complex shapes of aspherical and elliptical forms is avoided, and only the processing of a simple cylindrical surface is required, so there is an advantage of being able to process the mold more easily and reduce shape errors.

Since each insertion port (310) of the second optical transceiver module (300) contains an optical connector (500), the second optical transceiver module (300) includes as many optical connectors (500) as there are insertion ports (310). For example, the second optical transceiver module (300) of FIG. 14 includes two insertion ports and includes two optical connectors (500).
