GWR1000L optical node has one RF output, converting the optical signal from the headend into one 40dBmV CATV RF. GWR1000L is designed for universal Fiber to the Building (FTTB) application. The compact housing includes 60V or 220V AC power supply, Optical receiving unit with microprocessor controlled RF AGC, RF amplifier and optional return path optical transmitter. GWR1000L can be installed inside or outside the building without any extra line amplifier for less than 100 subscribers. The stable RF level enables the field installation and maintenance easier.

1)  Aluminum Die Cast Housing for universal installation
2)  Working at 1550nm/1310nm optical wavelength
3)  45~862/1002MHz RF bandwidth
4)  High performance and low power consumption GaAs Technology
5)  RF AGC maintaining one stable 40dBmV RF output
