HY-21-TA03 Serials field-type bidirectional EOC subscriber's amplifier is specifically designed for last “1km” of CATV transmission network. It has good property, low power consumption, high reliability, and excellent value for money, suitable for medium and small-scale bidirectional transmission network and multi-level transmission of trunk line or distribution networks with high requirements. It adopts MOTOROLA、 PHILIPS、 NEC imported module, with stable performance, low noise figure, high output level. It has two equalizers in the front end and in the back end with two outputs ports. Its branch and distribution can make change according to your needs. Its one input port and two output ports have over-current protection function (with over-current inserts shear inside). It is more convenient to debug because of the plug-in duplex filter, plug-in fixed(or adjustable) equalizer and attenuator, and the scientific and reasonable on-line detection ports.

The equipment can work steadily for a long time under bad outdoor environmental condition because of the aluminum waterproof housing, high reliability switching power supply and strict lightning protection system
