Description
Technical Field
The invention belongs to the technical field of optical communication, and particularly relates to a shell structure of an optical transceiver module.
Background
The 400G OSFP packaged high-rate optical transceiver module is a high-density, high-rate product solution designed specifically for optical communications, data center, and network market applications.
According to the provision of the OSFP multi-source protocol, the optical communication module has the characteristic of 'hot plug', namely, the module can be connected with or disconnected from equipment under the condition of not switching off the power supply. Since the optical communication module is usually required to be inserted and pulled when in use, the module is usually required to be provided with an unlocking device, so that the module can be smoothly separated from the installation cage of the equipment. When the OSFP optical module is inserted into an installation cage of equipment, the OSFP optical module is locked by mutual contact between structural steps on two sides of the optical module and cage locking plates, the module is fixed in the cage to work, when the module needs to be pulled out outwards, spring locking plates on the cage are jacked up by unlocking parts of pull rings of the optical module, so that unlocking of the optical module is realized, the module can be pulled out outwards at the moment, and finally the hot plug function of the optical module is realized. Therefore, the optical module needs to be structurally designed with an unlocking device to realize the function.
The 400G optical module adopts 8-channel full-duplex transceiving, and the transmission data rate of each channel is up to 50 Gbps. With the increasing transmission rate of optical modules, the optical transceiver module with high transmission rate is particularly prone to generate excessive EMI (electromagnetic radiation). An effective solution to EMI is to provide electromagnetic shielding on the product housing structure. Electromagnetic shielding is to reduce interference or damage caused by electromagnetic waves by using the attenuation effect of a shielding body on the electromagnetic waves. For the electromagnetic shielding of conductor materials, the best effect is achieved by using an integral metal shell, but in practical application, due to the problems of assembly requirements and processing precision, gaps inevitably occur between a module base and an outer cover and between an optical device interface and the base, so that the electromagnetic shielding effect of the whole optical module shell is greatly influenced. Therefore, in order to improve the electromagnetic shielding performance of the optical module housing structure, it is necessary to eliminate or reduce holes and gaps from the inside to the outside of the module as much as possible in design.
The total power consumption of the 400G OSFP packaged high-speed optical transceiver module can exceed 15W at most, so the problem of heat dissipation needs to be considered particularly in the optical module housing structure.
