Problems solved by technology

[0003] Using two 4-wavelength integrated optical transceiver components to realize a 400G optical module requires adding two devices, an optical demultiplexer and an optical multiplexer, inside the module shell. In the prior art, one implementation is to separate the two components of the multiplexer The device is installed inside the module in the form of a pigtail, which will occupy a large space inside the module, and it is difficult to install and operate to connect the optical transceiver component with the splitter and multiplexer, and it may fall due to manual operation or transportation. For other reasons, the optical fiber inside the module is easy to cause damage or breakage, which directly causes problems such as unqualified or failure of the optical module.

Embodiment approach 1

[0036] An optical interface device for an optical splitter and multiplexer for high-speed optical modules provided by the present invention, the internal structure and function block diagram of the first embodiment is as follows figure 2 As shown, it includes: a packaging case 102, an external optical interface unit 100, two internal optical interface units 118 and 119, and an optical splitting or combining optical unit. Wherein: the packaging case 102 includes an installation space, and provides a coupling hole 110 for the external interface, and two coupling holes 111 and 112 for the internal interface. Wherein, the installation and assembly space is used for installing and fixing the packaged optical splitting or multiplexing optical unit. The external interface coupling hole 110 is used for installing the external optical interface unit 100 , and the size of the external interface coupling hole 110 should allow the external optical interface unit 100 to be partially inser...

Embodiment approach 2

[0045] The functional block diagram of the internal structure of Embodiment 2 of the present invention is as follows image 3 As shown, it includes a packaging case 202, an external optical interface unit 200, two internal optical interface units 218 and 219, and an optical splitting or combining optical unit. The functions / structures of the external optical interface unit 200 and the internal optical interface units 218 and 219 are the same as those described in the first embodiment. The packaging case 202 includes an installation and assembly space, and provides a coupling hole 210 for the external interface, and two coupling holes 211 and 212 for the internal interface. The above coupling holes are also consistent with the functions / structures described in the corresponding components in Embodiment 1 . The difference between Embodiment 2 and Embodiment 1 mainly lies in the structure of the optical unit for optical wave splitting or multiplexing. In Embodiment 2, a light wa...

Embodiment approach 3

[0049] Embodiment 3 is a symmetrical structure of Embodiment 2, and its function and implementation are consistent with 2, such as Figure 4 shown.

[0050] λ described in the present invention 1 ,λ 2 ,λ 3 ,λ 4 ,λ 5 ,λ 6 ,λ 7 ,λ 8 The eight wavelengths are LAN-WDM wavelengths defined by the IEEE802.3bj standard.

[0051] The optical port device of the optical demultiplexer and multiplexer described in the present invention can be installed in CFP series and QSFP-DD high-speed optical module packaging structures.

[0052] In the present invention, the positions of the external and internal interfaces can be adjusted according to the definition of the size of the high-speed optical module, but the overall frame will not change fundamentally. At the same time, the turning edges and corners added in the optical path can adjust the optical path at a small angle, compensating for the device processing and The optical path mismatch caused by assembly greatly reduces the requ...

Abstract

The invention relates to an optical interface device of an optical demultiplexer / multiplexer for a high-speed optical module. The optical interface device comprises a packaging shell, an external optical interface unit, two internal interface units and a demultiplexing / multiplexing optical unit. The external optical interface unit is mounted at an optical fiber interface position of the high-speed optical module and is used for accessing a connection optical fiber. The internal interface units are connected with an optical transceiving assembly. The demultiplexing / multiplexing optical unit in the packaging shell is used for demultiplexing / multiplexing optical signals on an optical fiber link. The device provided by the invention is used at the optical interface position of the high-speed optical module, and the optical fiber link out of the module and the optical transceiving assembly in the module can be connected easily. The device is small in structure, thereby facilitating miniaturization of the module. In the manufacturing and assembling process of the high-speed optical module, through adoption of the device provided by the invention, the high-speed optical module can be mounted and adjusted rapidly, and the assembling and debugging process is simple and rapid. No optical fiber is coiled in the module, so the optical fiber is prevented from being damaged or broken and the reliability of the module is improved, thereby facilitating the mounting and manufacturing of the high-speed optical module.
