Description
The SFP+transceiversare high performance, cost effective modulessupporting datarate of 10Gbps and 20km transmission distance with SMF.
The transceiver consists of threesections: 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.
Thetransceivers are compatible with SFP Multi-Source Agreementand SFF-8472 digitaldiagnostics functions.
