Description
Springtek SFP transceivers are high performance, cost effective modules supporting 1.25Gbps and 40km transmission distance with SMF.
Springtek SFP transceivers are high performance, cost effective modules supporting 1.25Gbps and 100km transmission distance with SMF.
The transceiver consists of three sections: a 1550nm LD 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.
