An optical port device of an optical splitter and multiplexer for high-speed optical modules

Abstract

The invention relates to an optical demultiplexing and combining optical port device for a high-speed optical module, which includes a packaging shell, an external optical interface unit, two internal interface units, and a demultiplexing and combining optical unit. The external optical interface unit is installed at the optical fiber interface position of the high-speed optical module for accessing and connecting optical fibers. The internal optical interface unit is connected to the optical transceiver component. The demultiplexing and multiplexing optical unit inside the packaging shell realizes the optical signal on the optical fiber link. of dividing and combining waves. The inventive device is used at the optical port of a high-speed optical module, and can easily connect the optical fiber link outside the module to the optical transceiver component inside the module. At the same time, due to its compact structure, it is conducive to the miniaturization of the module. The inventive device can be quickly installed and adjusted in the production and assembly of high-speed optical modules. The assembly and debugging process is simple and fast. At the same time, because there is no optical fiber coiled in the module, damage or breakage of the optical fiber is avoided, which improves the reliability of the module and is beneficial to high-speed optical modules. Module installation and production.

Description

technical field [0001] The invention relates to an optical communication device, in particular to an optical splitter and multiplexer optical port device used for a high-speed optical module, and belongs to the field of optical communication. Background technique [0002] With the rapid development of the optical communication field, the number of Internet users, application types, and network bandwidth have all shown explosive growth.

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.
