Specifaction
GN-2R-M outdoor optical workstation is mainly used in FTTB structural CATV bi-directional HFC network.Adopt modular mechanical combination structure,RF amplifier unit and switching power supply module share one modular frame in the bottom cover.The top cover can be configured 1 forward Optical Receiver module.1 reverse Optical Transmitter module and 1 class responder module.


Feature
Advanced optical AGC function,the input optical power range up to -9~+2dBm.
Downlink RF operating bandwidth extended to 1 GHz,the highest output level more than 108dBuV.
Professional RF electrical adj ATT chip,RF electrical adjustable equilibrium circuit,good linearity,high precision.
The return path adopts professional RF electrical adj ATT chip instead of the three-state switch.
Reverse transmitter configure burst mode,sharply decrease the noise collection and reduce the front-end receivers no.
Full CPU control the machine work,LCD displays the parameters,and can be configured national standard II class network managemaent responder.
The structure adopts embedded modular design,easy to maintain and replace.
