＊ L-Band Optical Transmitter GFS1310-LA
|
Brief Introduction
L-Band Optical Transmitter GFS1310-LA realizes 950~2150MHz satellite signal’s long distance transmission over optical fiber. It functions to convert the L-Band satellite signal into 1310nm optical signal. At the receiving end, one L-Band optical receiver should be used.
Product Features
- 1310nm wavelength, 950~2150MHz working frequency.
- MQW DFB laser ensures good specifications and high reliability.
- MGC and AGC functioned for L-Band RF.
- Loop out port is built for L-Band RF input.
- Input port provides LNB with 13V/17V power supply.
- SNMP net-management function optional. Connected to computer through RJ45 port and with software installed on computer, device’s working parameters could be monitored.
- Standard 19’ one rack unit chassis.
