GigaXtend GMC 1.8GHz High Gain Dual (HGD) System Amplifier

The ATX GigaXtend™ GMC 1.8GHz High Gain Dual (HGD) System Amplifier is designed to assist cable operators in evolving their HFC networks to meet subscriber demand, while fully leveraging previous outside plant investments. GigaXtend GMC 1.8GHz amplifiers’ modular design allows MSOs to upgrade their outside plant through tray upgrades or entire station replacements. Cable operators can upgrade 1GHz or 1.2GHz GainMaker/GigaXtend housings to support 1.8GHz through a simple drop-in upgrade.

GigaXtend 1.8GHz System Amplifiers are available in the original GainMaker housing, as well as a new, wider housing that offers increased thermal dissipation, allowing for future enhancements. Both housings enable technicians to replace entire system amps without the need for extension fittings. The ATX GigaXtend GMC 1.8GHz HGD System Amplifier provides two high-level forward RF outputs (main and auxiliary), with the option to create a third RF output by using an optional plug-in auxiliary path signal director.

In compliance with the SCTE 279 2022 specifications, ATX has fortified GigaXtend GMC 1.8GHz amps with new maintenance and control intelligence. Auto-alignment and all-electronic level and slope control reduce the learning curve for technicians, significantly streamlining installation and maintenance operations. Technicians can configure and tune amps using a phone or other connected device through a USB or wireless/Bluetooth connection. An optional transponder is available for cable operators desiring additional monitoring or remote-control capabilities.

Benefits

  • Trouble-Free Installation and Maintenance: ATX has fortified GigaXtend GMC 1.8GHz amps with new maintenance and control intelligence. Auto-alignment and all-electronic level and slope control reduce the learning curve for technicians, significantly streamlining installation and maintenance operations. Technicians can configure and tune amps using a phone or other connected device through a USB or wireless/Bluetooth connection. An optional transponder is available for cable operators desiring additional monitoring or remote-control capabilities.
  • Inventory Reduction: By eliminating plug-in pads and equalizers in favor of a software-based configuration, GigaXtend GMC 1.8GHz amps support automatic alignment and set-up through pre-sets and configuration files controlled through a local craft interface. In addition to reducing installation time and human error, moving to software-based installation will help technicians trim required inventory levels by potentially dozens of devices.
  • In-Field Upgrades: Designed to minimize service disruptions, GigaXtend 1.8GHz amps simplify and speed upgrade procedures, such as adjustments to upstream spectrum allocation. In addition to reducing customer disruptions, the improved upgrade process eliminates the need for technicians to execute bench upgrades, which can increase the amount of time, complexity and resources required to upgrade critical equipment.
  • Investment Protection:In addition to backward compatibility with the GainMaker installed base, GigaXtend GMC 1.8GHz amplifiers provide a seamless upgrade path from ATX’s GigaXtend 1.2GHz family of amplifiers. A seamless segue from 1.2GHz to 1.8GHz ensures that cable operators purchasing GigaXtend 1.2GHz amps today will have a regret-free path to DOCSIS 4.0 and 10G in the future.
