Product Description
CATV Trunk Amplifier feature:
1. CATV Amplifier adopt low noise Philips or NEC imported module, power doubler module or Gallium Arsenide module output, non-linear index is high.
2. Equalizer, attenuator have fixed and adjustable structure for selection.
3. Output splitter or coupler can plug change to make engineering debug more agile.
4. Forward and reverse fore-and-aft have independent test port, easy to debug.
5. Return channel adopt Philips or Motorola amplify module, good quality duplex filter, plug fixed attenuators and equalizers, makes it high C/N, easy to debug.
6. High reliable switch power and strict anti-thunder system fit for safe steady work in worse weather.
7. Suitable large or middle-size bi-directional network main trunk signal transmission, can substitute imported and famous brand machine.
