Product Descriptions
Olinkcom's OLSP8512L-C(I)DS5 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 VCSEL 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 (MSA) and SFF-8472.
