A high-speed optical module passive device custom fiber length fixture

Abstract

The invention relates to a high-speed optical module passive device custom-made fiber length jig, which comprises a bottom plate, an optical fiber array base, an MT base, two locking mechanisms, a plurality of movable positioning blocks and a positioning adjusting assembly. The optical fiber array base and the MT base are arranged at the two ends of the bottom plate in a relatively sliding mode respectively, the two locking mechanisms are movably arranged on the lower surface of the bottom plate respectively, the positioning adjusting assembly is arranged on the bottom plate, and the multiplemovable positioning blocks are arranged on the positioning adjusting assembly side by side. The optical fiber array base and the MT base are arranged on the bottom plate in a sliding manner; the relative distance between the optical fiber array base and the MT base is convenient to adjust; the locking mechanism is used for locking, meanwhile, the distance between the movable positioning block andthe MT base can be adjusted through the positioning adjusting assembly, the distance between the MT base and the movable positioning block in the high-speed optical module passive device can be conveniently set, so that customization of the corresponding fiber length is realized, the jig is very convenient, the production efficiency is greatly improved, the production cost is reduced, and the consistency of products is good.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a fiber length fixture for customizing high-speed optical module passive components. Background technique [0002] With the rapid development of communication technology and the rapid growth of practical applications, research on large-capacity optical fiber communication systems has great application value. At present, the optical communication module mainly includes a sending end and a receiving end. In order to expand the bandwidth of the optical module, the sending end usually uses a set of lasers and a set of micro LC connectors to connect to the outside, while the receiving end mostly uses an optical fiber array and a PD array to connect, so a A group of micro LC connectors and fiber optic arrays and MT connectors form passive components to communicate with the outside. The structure of passive components is as follows figure 1 shown. Because the volum...

Problems solved by technology

In the prior art, there is no high-speed optical module passive device that can achieve customized fiber length. If the fiber length is manually measured and adjusted repeatedly, on the one hand, the efficiency is relatively low, and on the other hand, a large amount of optical fiber raw materials will be wasted, which will greatly increase the production cost.
