Product Description
The FTCS-B1512-40DI SFP transceivers are high performance, cost effective modules supporting data rate of 1.25 Gbps and 40 km transmission distance with SMF. The transceiver consists of three sections: a DFB 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.
