GigaWave: Digital Link Amplifier – HUB (DLA-HUB)

The GigaWave Digital Link Amplifier-HUB (DLA-HUB) is a field-hardened, gain-flattened EDFA platform optimized for digital optical transport in long-distance multi-wavelength applications for cable operators, telecom companies, utilities and other service providers. A critical design feature of ATX’s DLA-HUB is integrated dispersion compensation that delivers extended reach and improved performance compared to external pre- or post-dispersion compensation modules (DCMs). The solution has packaging options for pedestal, street cabinet, underground vault or aerial strand mounting.

The GigaWave DLA-HUB, along with the GigaWave Digital Link Extender (DLX) multi-wavelength digital optical transport platform, form the core of ATX’s Long-Reach Digital Optical Transport Solution.

In addition to long-reach transport applications, the ATX DLA-HUB platform supports multiple use cases:

  • Hub eliminations
  • Node segmentation
  • Distribution networks
  • FTTX networks


  • Close the Digital Divide by cost-effectively extending the reach of your network to deliver broadband services to unserved and underserved communities. 
  • Pursue government-funded broadband initiatives through a technology foundation that overcomes historical barriers to serving far-flung service areas. 
  • Support a variety of configuration and deployment options, including add/drop capabilities, to enable cable operators to maximize the utility of their optical networks in low-density service areas. 
  • Reduce operational cost and complexity through superior dispersion compensation technology that enables cable operators to extend their optical networks using fewer amplifiers. 
  • Expand your broadband footprint and help to offset declines in video services by reaching new communities with innovative and profitable services.


  • EDFA modules optimized for digital optical transport (any SFP) to support HFC DAA or PON
  • Low noise figure
  • Multiple gain options with an optimal output power
  • Integrated 40km dispersion compensation, offering optimal link budget
  • Excellent gain flatness for multi-wavelength digital applications over the entire power range
  • Field-hardened, strand, pedestal or wall mounting
  • Redundant powering
  • Controller card for status monitoring (SNMP, HTML GUI, TACACs security)
