Gigalight SFP+ER 1550nm Transceiver is a “Limiting module”, designed for 10GBASE-ER, and 2G/4G/ 8G/10G Fibre- Channel applications.
The transceiver consists of two sections: The transmitter section incorporates a cold EML laser. And the receiver section consists of a PIN photodiode integrated with a TIA. All modules satisfy class I laser safety requirements.
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
