Optical module

Abstract

The invention application provides an optical module comprising an upper housing and a lower housing mutually buckled; multipath optical devices are electrically connected with a circuit board on thelower housing so as to transmit photoelectric signals; the optical module also comprises a pedestal arranged on the lower housing and a side plate connected on one side of the pedestal; a plurality ofgrooves are arranged in the pedestal; optical devices connected with optical fiber heads are clamped in the grooves; the optical fiber heads and springs sleeved on the optical fiber head end portionsare supported by the grooves; poles arranged on the side plate insert into the grooves and abut against the springs; a cover plate covering the optical devices is detachably connected with the pedestal. The springs can support the optical fiber heads and adjust the fitting allowance of the optical fiber heads in the grooves, thus preventing the optical fiber heads from having offsets in the pedestal, and effectively ensuring the working performance of connected optical devices and fibers; the optical devices and optical fiber heads of the optical module are convenient to assemble, thus effectively reducing the optical module assembling workload.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical module. Background technique [0002] An optical network refers to a network structure that uses optical fiber transmission, and an optical module is a core device that transmits optical signals through optical fibers and completes photoelectric conversion in the optical network. With the continuous development of optical communication technology, the amount of information and data transmitted on the optical network is gradually increasing, and the optical module based on the form of a single optical device cannot meet the user's requirements for transmission rate and transmission capacity due to the limited transmission bandwidth. . In order to meet the user's demand for high bandwidth and improve the transmission rate and capacity of the optical module, a multi-channel parallel optical module packaged with multiple optical devices emerged as the times ...

AI Technical Summary

Problems solved by technology

In the existing multi-channel parallel optical modules, multiple sets of transmitting and receiving optical devices used to transmit signals are usually arranged in a matrix, and the optical fiber heads corresponding to the transmitting and receiving optical devices are fixed by dispensing. On the base of the optical module, the assembly work is more complicated. Once the optical fiber head is fixed by dispensing, it is difficult to adjust its fixed position. If the position of the optical fiber head is not adjusted to the best position, it will directly affect the performance of the optical device. , at the same time, the plugs of each optical device are set in one piece, and its overall size is large, which is not conducive to the miniaturization design of optical modules
