TELESTE AC 1000 Amplifying platform

0
Усилительная платформа TELESTE AC 1000

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.
