1. Summary
Design for bi-directional network trunk transmission. Inner structure is perfect with high index and good dependability, easy to test. Suitable for large or middle-size network which need high index.

2. Performance Characteristic
Adopt low noise Philips or Motorola imported module, power doubler 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.
