1.25gbps 1310nm Sm Duplex Lc 20km Fiber Optic Sfp Module
Description of 1.25g sfp module
The SFP transceivers are high performance, cost effective modules
supporting dual data-rate of 1.25Gbps/1.0625Gbps and 20km
transmission distance with SMF.
The transceiver consists of three sections: a 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.
The transceivers are compatible with SFP Multi-Source Agreement
(MSA) and SFF-8472. For further information, please refer to SFP
MSA.
