Your Outside Plant

Upgrade your HFC network with GigaXtend next-gen actives and passives


Backward-Compatible. Forward-Looking.
Extending the lifespan of the HFC network

Taking the next step in evolving the broadband network leaves many service providers seeking ways to stretch their HFC network investments while providing competitive performance on their road to 10G. ATX’s GigaXtend™ actives and passives are designed to cost-effectively extend the lifespan of HFC networks by 30 years or longer. The GigaXtend family of GainMaker®-compatible (GMC) amplifiers and hardline taps and passives are backward compatible, while also supporting 1.8GHz and higher frequencies, allowing cable operators to extend the life of their HFC network while increasing capacity. And as the only 204MHz digital return solution for Cisco® GS7000 nodes, ATX’s GigaXtend Digital Return transmitters and receivers give cable operators the ability to boost upstream capacity and offer 1Gbps symmetrical service options.

Still the only authentic Cisco GainMaker-compatible amplifier on the market and soon to be manufactured in the USA, ATX’s GigaXtend GMC amplifiers deliver reliability and are drop-in upgradeable, which helps to reduce service interruptions and labor costs.

As a market leader, ATX works closely with ecosystem partners and standard bodies to drive innovative HFC solutions to the next level and provide MSOs a seamless DOCSIS® 4.0 transition – another way ATX helps communication service providers futureproof and evolve their networks in lockstep with market demand.
