Description:
ATOP SFP（DDM） transceiver is high performance, cost effective module. It is designed for Gigabit Ethernet and 1x Fiber Channel applications. The transceiver consists of two sections: The transmitter section incorporates a 1310nm FP laser. And the receiver section consists of a PIN photodiode integrated with a trans-impedance preamplifier (TIA). All modules satisfy class I laser safety requirements. ATOP SFP transceiver provides an enhanced monitoring interface, 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. For further information, please refer to SFP MSA and SFF-8472.
