Simple and reliable

Designed quality and robustness in mind, the CX3 not only provides reliable performance, but also ensures great usability through a local user interface. All this comes in a compact format, making the CX3 a great all-around amplifier for modern bidirectional networks, in which cost efficiency and easy installation are prime concerns.

Smooth migration

The new CX3 amplifier offers operators a smooth migration path to DOCSIS 3.1-compliant technologies. It can be used in 860 MHz / 1 GHz / 1.2 GHz networks while the return path supports frequencies up to 65 MHz, 85 MHz and 204 MHz.

Local user interface

The CX3 has a local user interface consisting of a four digit 7-segment display and three push buttons.
