¡ö L-Band Optical Receiver GJS-LA
|
Brief Introduction
L-Band Optical Receiver GJS-LA functions to convert the received optical signal back into L-Band RF. With L-Band optical transmitter and receiver, 950~2150MHz satellite signal could be transmitted over longer distance than coaxial cable.
Product Features
- 1290~1580nm wavelength, 950~2150MHz working frequency.
- Adopts APD to complete the O/E conversion.
- Dual L-Band RF outputs.
- MGC and AGC functioned for L-Band RF.
- Built with high precision temperature compensation circuit to stabilize APD’s output level.
- 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.
