Description:
This amplifying platform is a super-power amplifier with a gain of 39 dB and a possibility of its modification to a full optical receiver. The amplifiercan be used both for thetrunk and for distribution network; at the same time, afterthe splitterinstallation there will be three outputs.
Advantages:
excellent features and characteristics;
a possibility of its modification to the optical receiver, there is a place foran optical backward channel receiver;
modular, upgradable structure;
all amplifier stages are fabricated using GaAs technology;
there are from one to three RF outputs;
automatic gain control;
plug-in backward channel module;
monitoring system;
removable diplex filters of backward channel;
high level of shielding.
