Product Description

120km gigabit sfp module transceiver ddm 1550nm cisco 


Sfp optical module are a small pluggale optical signal transceiver,with different working speed from 155M,655M,1.25G,2.5G,8G,10G,40G even to 200G for optiction,it's more flexible with sfp port,can adjustive to any distance & single or dual fiber with the same protocol,main sfp optical module has different below type,Xenpak,Gbic,XFP,SFP(Mini Gbic) & copper sfp,pic as below.


Description:
The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps/1.0625Gbps and 120km transmission distance with SMF.

The transceiver consists of three sections: a DFB laser transmitter, a APD 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.

Features:Dual data-rate of 1.25Gbps/1.063Gbps operation1550nm DFB laser and APD photo detector for 120km transmissionCompliant with SFP MSA and SFF-8472 with duplex LC receptacleDigital Diagnostic Monitoring:Internal Calibration or External CalibrationCompatible with SONET OC-24-LR-1Compatible with RoHS+3.3V single power supplyOperating case temperature:Standard :  0 to +70°C   Extended : -20 to +85°C
