GWR1000 optical node provides network operator the flexibility to fulfill network need and optimize network source. Both forward path receiver and return path transmitter have the same modular design for easy field installation and maintenance. The optical power indicator and RF test port on the module assist the operator checking the node status. User-friendly cover board indicates the main functions of the node. The standard outputs of GWR1000 optical node are 2 independent RF ports and additional 2 split ports can be added upon request. With high quality FP laser or DFB laser, the return path transmitter module set up a reliable return path optical link. User can power the GWR1000 by 220V AC or 60V AC.
Features:
1550nm/1310nm dual wavelength
862MHz/1000MHz/1200MHz GaAs technology and RF output up to 48dBmV
Plug-in diplexer filter, slope circuit, attenuation circuit
2 independent RF ports with or without 2 additional split outputs
All-in-one design of return transmitter module for easy upgrade
-20dB test ports in forward and return module
AC ~220V or ~60V power supply with surge and lightning protection
Independent 60V AC Power Input Port
