摘要： An optical transceiver and a pluggable system to enhance the reliability of the communication between the optical transceiver and the host system are disclosed. The rear of the housing of the transceiver provides a periodic structure, a plurality of hollows or a plurality of projections, arranged along the gasket provided in the host connector. Only portions of the periodic structure come in contact with the gasket, and the repulsive force caused by the gasket is consequently weakened to enhance the reliability of the mating of the plug in the optical transceiver with the host connector. The width of the hollows, or the pitch of the projections is set to be shorter than a quarter wavelength of a signal transmitted between the transceiver and the host system to reduce the EMI radiation leaking from the end of the transceiver.
摘要翻译：公开了一种用于增强光收发器和主机系统之间的通信的可靠性的光收发器和可插拔系统。收发器的壳体的后部提供沿着设置在主机连接器中的垫圈布置的周期性结构，多个中空或多个突起。只有周期性结构的一部分与垫片接触，并且由垫圈引起的排斥力因此被削弱，以提高插头在光收发器中与主机连接器的匹配的可靠性。空穴的宽度或突起的间距被设定为短于在收发器和主机系统之间传输的信号的四分之一波长，以减少从收发器的端部泄漏的EMI辐射。

摘要： An optical receiver module that receives a wavelength multiplexed light and a process to assemble the optical receiver module are disclosed. The optical receiver module provides a coupling unit to collimate the wavelength multiplexed light and a device unit that installs an optical de-multiplexer and photodiode elements within a housing. The front wall of the housing through which the wavelength multiplexed light passes is polished in a right angle with respect to the bottom of the housing.
