1.25Gbps 1550nm 120km CWDM SFP Optical Transceiver GSC-12xx-12C(D) for optical transmission systems

 

GSC-12xx-12C(D)

1.25Gbps CWDM SFP Optical Transceiver, 120km Reach

 

Features:

♦ Data-rate of 1.25Gbps operation

♦ 18 CWDM DFB wavelengths laser and APD photodetector for 80km 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 range of 0°C to +70°C(Commercial)

 

Applications:

♦ Gigabit Ethernet

♦ Fiber Channel

♦ Switch to Switch interface

♦ Switched backplane applications

♦ Router/Server interface

♦ Other optical transmission systems

 

Description:

The SFP transceivers are high performance, cost effective modules supporting data-rate of 1.25Gbps and 120km transmission distance with SMF.
The transceiver consists of three sections: an uncooled CWDM DFB laser transmitter, an 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.
