The SFP transceivers are high performance, cost effective modules supporting data-rate of 1.25Gbps and 20Km transmission distance with SMF.
The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integratedwith a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safetyrequirements.
The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. Forfurther information, please refer to SFP MSA.
