PRODUCT DESCRIPTION
Transceiver consists of three sections: an uncooled FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.
Transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.
The SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of 155Mbps and 20km transmission distance with SMF.
