Description

SFP+ZR Transceiver is designed for 8.5G/10G Fiber-Channel and 10GBE applications. The transceiver consists of two sections: The transmitter section incorporates a cold EML laser. The receiver section consists of an APD photodiode integrated with a TIA. All modules satisfy class I laser safety requirements. SFP+ZR Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power, and transceiver supply voltage.
