PRODUCT DESCRIPTION
Optical module also be called optical fiber module, the translation should be transceiver module. The function of the optical module is the photoelectric conversion, and the transmitter converts the electrical signal into the optical signal. After the transmission through the optical fiber, the receiving end converts the optical signal into the electrical signal. SFP28 is a kind of optical module.
The 25Gbps 850nm Fiber Optic Module is a multi-rate 850nm transceiver which ensures compliance with 25GBASE-SR specifications. Per the requirements of 25GE, inter-nal clock and data recovery circuits (CDRs) are present on both electrical input and electrical output of this trans-ceiver. These CDRs will lock at 25.78 Gb/s. Digital diagnostic monitoring information (DMI) is present in the 25Gbps 850nm Fiber Optic Module per the requirements of SFF-8472, providing real time monitoring information of transceiver laser, receiver and environment conditions over a SFF-8431 2-wire serial interface
