The SFP transceivers are high performance, cost effective modules supporting data rate of 1.25Gbps and 550m transmission distance with MMF.
The transceiver consists of three sections: a VSCEL laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.
The transceivers are compatible with SFP Multi-Source Agreement and SFF-8472 digital diagnostics functions.
