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.
