Description
The Wiitek CSFP transceivers are high performance, cost effective modules supporting 2.488Gbps and 20km 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 Compact SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA. |
