Description
Springtek SFP transceivers are high performance, cost effective modules supporting 1.25Gbps and 550m transmission distance with MMF.
The transceiver consists of three sections: a 850nm VCSEL transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA).Springtek SFP modules satisfy class I laser safety requirements.
The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.
