Description

Product Summary

HT—SXG Series CATV Two-way Amplifier mainly applies to the trunk, and the distribution amplification of the two-way cable network. The series reserving two-way type products can be upgraded to the two-way products just need to insert the duplex filter and reverse amplification module, and it has no impact on the indicators of the original one-way.

Product Characteristic

Adopting excellent waterproof aluminum casting housing, for indoor and outdoor use, moisture-proof and waterproof, comply with IP24 norms.

Excellent thermal structural design, to improve the heat dispersion of the housing and the reliability of the amplifier.

Using pluggable structure, easy for the upgrade of the whole set.

According to the need, the equilibrium can be divided into fixed and adjustable type.

Built-in pluggable splitter, to reduce the trunk interface and improve the performance index and reliability of the transmission system.

The front stage adopts push-pull module, and the rear stage adopts power multi-amplification module output.

Selection of different frequency segentation modes only requires to replace the duplex filter.
