ATX’s family of optical nodes and hubs are designed to enable cable operators to expand the reach and performance of their networks by centralizing rich functionality in compact spaces. The GigaXtend™ UN3000 is a universal access node platform designed to support current and future technologies and architectures, including DOCSIS® 3.1, DOCSIS® 4.0 and Extended Spectrum DOCSIS (ESD). The ATX I-HUB is a field-hardened outside hub designed to enable MSOs to deploy optical solutions that eliminate the need for costly brick-and-mortar hub sites and streetside pedestals.

GainMaker Optoelectronic Node 1GHz GainMaker Optoelectronic Node 1GHz

The GainMaker® Node is designed to serve as the cornerstone of today’s emerging fiber deeper network architectures.  The GainMaker Node combines the superior proven technologies of both the GainMaker RF Amplifier and Prisma® Optical components.  Available with two or three high level RF output ports, it is the ideal platform for delivering video (digital and analog) as well as high-speed data services over advanced hybrid fiber/coax (HFC) networks.  With its modular design of fiber receiver, reverse fiber transmitter and RF amplifier electronics, the GainMaker Node station can provide the full complement of functions required by advanced networks.

The GainMaker Node accommodates a second forward receiver with an RF switch to accommodate forward path optical redundancy.  Reverse traffic can be combined and routed to FP, DFB, or CWDM reverse transmitters.  The High Gain Dual launch amplifier module provides two high-level outputs (with the ability to split one internally to feed a third port).   Additionally, the GainMaker Node is available with an optional custom status monitoring transponder for use with Scientific-Atlanta’s ROSA / TNCS status monitoring and control element manager.  On-board temperature, automatic gain control (AGC) levels, RF switch position, power supply condition, as well as other features/parameters can be monitored through this transponder.

Installation of the GainMaker Node is quick and easy.  The GainMaker Node can be ordered as a complete node or as an upgrade kit for existing GainMaker System amplifiers.  The fiber receiver is delivered with preconnectorized fiber terminations.  The optional preconnectorized cable stub is the ideal method for connecting the GainMaker Node to the fiber network (see cable stubs data sheet).  External termination connectors are also available for central strength member and LXE style fiber optic cables.  The GainMaker Node includes a 4-fiber handling tray for these cables.

System reliability and upgrade flexibility are integral to the construction of the GainMaker Node.  Key features include a chromate plated housing to withstand harsher operating environments, local status monitoring of each module, and a 1 GHz housing for future higher bandwidth applications.

GigaXtend Universal Access Node GigaXtend Universal Access Node

ATX’s next-generation universal node is a forward-looking, futureproof solution that enables MSOs to fully capitalize on the capabilities of Distributed Access Architecture (DAA) and digital technologies, while seamlessly accommodating future technologies and architectures as they become available.

The GigaXtend™ UN3000 delivers superior power dissipation. Its built-in support for future spectrum expansion to 3GHz and higher empowers MSOs to address near-term requirements for Remote PHY Device (RPD) or Remote MAC-PHY Device (RMD) applications, as well as provides a roadmap for future and simultaneous support of additional DAA applications, including DOCSIS® 4.0, Extended Spectrum DOCSIS® (ESD), Remote OLT, wireless backhaul and Internet of Things (IoT). The unit’s new and environmentally-hardened housing ensures that MSOs are able to realize the unfettered evolution of their networks without the need to replace expensive outside plant equipment for the next several years.


For short to medium haul applications, ATX supplies a range of cost-effective, field-hardened optical amplifiers. Versions are available with single and multiple output ports and at various output powers in either single or double slot modules. The I-HUB EDFA is ideal for RFoG and other cable applications.

The high-performance ATX EDFA has been deployed for numerous applications:

  • Long haul super-trunking
  • Hub eliminations
  • Node segmentation
  • Distribution networks
  • RFoG applications
  • FTTx networks
