Product Description

40km/80km/120km 1.25Gbps CWDM SFP Optical Transceiver

Description
The SFP transceivers are high performance, cost effective modules supporting data-rate of 1.25Gbps and 40km transmission distance with SMF.
 
The transceiver consists of three sections: an uncooled CWDM 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 SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.

Features
Data-rate of 1.25Gbps operation
18 CWDM DFB wavelengths laser and PIN photodetector for 40km transmission
Compliant with SFP MSA and SFF-8472 with duplex LC receptacle
Digital Diagnostic Monitoring:Internal Calibration or External Calibration
Compatible with SONET OC-24-LR-1
Compatible with RoHS
+3.3V single power supply
Operating case temperature:Standard :  0 to +70°C

Applications
Gigabit Ethernet
Fiber Channel
