Optical transceiver module housing and optical transceiver module

Abstract

The invention relates to the technical field of optical communication and provides an optical transceiver module housing comprising a housing, a cover body for sealing the housing, and a handle that can sleeve the housing. The cover body is detachably mounted on the housing. The housing has a cavity for installing a light emitting device and a light receiving device. A side of the housing is provided with a first through hole and a second through hole for the light emitting device and the light receiving device to be inserted respectively. The handle has two bar-shaped locking pieces. Lockingheads are disposed at the end portions of the two locking pieces. Both sides of the housing are provided with first grooves for the two locking heads to be engaged with respectively. An optical transceiver module is also provided which includes a light emitting device, a light receiving device, and the above optical transceiver module housing. The optical transceiver module housing and the opticaltransceiver module each leads to the outside via the two through holes such that the possibility that electromagnetic waves leave from other slits is greatly reduced. Locking and unlocking can be easily achieved by engaging or disengaging the locking heads on the locking pieces with a first recess.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical transceiver module shell and an optical transceiver module. Background technique [0002] The development trend of high integration and high speed of optical communication modules will inevitably make optical modules continue to develop in the direction of high speed, miniaturization, and high density. Therefore, QSFP28 pluggable 100G high-speed optical transceiver module came into being. QSFP28 optical module is a high-density, high-speed product solution designed for optical communication, data center and network market applications. The cost and power consumption of a data center is one of the important factors that its builders need to consider, which is also an important driving force for the development of the optical communication market. Looking back at the development history of 100G optical modules, the development and improvement of its packag...

Problems solved by technology

[0003] However, QSFP28 is currently facing two problems. One is: because the optical communication module often needs to be plugged and pulled out when in use, it is usually required that the module has an unlocking device so that the module can be removed from the installation cage of the equipment smoothly. The other one is: with the continuous improvement of the transmission rate of the optical module, the high-transmission optical transceiver module is particularly prone to excessive EMI (electromagnetic interference). The effective way to solve EMI is to do electromagnetic shielding on the product shell structure. The electromagnetic shielding of conductor materials is best realized with an integral metal shell, but in practical applications, due to assembly requirements and processing accuracy issues, there will inevitably be gaps between the shell and the cover, and between the optical device adapter and the shell , thus greatly affecting the electromagnetic shielding effect of the entire optical module housing
