. Summary:
It is standard imported double-module structure bi-directional trunk amplifier. Inner structure is whole and easy to debug. High gain, output and index, it is suitable for large or middle-size network bi-directional trunk transmission. Use at behind 10-class of optical work station can get better effect.
2. Performance Characteristic:
Adopt low noise Philips or Motorola imported module, power double module or Gallium Arsenide module output, non-linear index is high.
Equalizer, attenuator have fixed and adjustable structure for selection.
Output splitter or coupler can plug change to make engineering debug more agile.
Forward and reverse fore-and-aft have independent test port, easy to debug.
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.
High reliable switch power and strict anti-thunder system fit for safe steady work in worse weather.
Suitable large or middle-size bi-directional network main trunk signal transmission, can substitute imported and famous brand machine.
