GWR1000L-W is a FTTB CATV optical receiver with 1310nm/1490nm WDM, receiving 1550nm CATV RF optical signal from Passive Optical Network (PON) while passing 1310nm and 1490nm digital signals to adjacent ONU device. GWR1000L-W has dual RF outputs, each at 46dBmV with RF AGC. Together with ONU and EoC system, GWR1000L-W provides one fiber to the building solution with both TV and Ethernet services for the whole building. GWR1000L-W enables Greatway ONU or any third party ONU to serve subscribers with dual Single 50dBmV or dual 46dBmV RF outputs capability.

1)  Compact indoor FTTB design
2)  Working at 1550nm optical wavelength
3)  50~1000MHz RF bandwidth
4)  High performance and low power consumption GaAs Technology
5)  RF AGC maintaining a stable RF output
6)  Dual RF outputs
7)  Bypass 1310nm/1490nm wavelengths to SC/UPC port
