« Large Business Data Services

AT&T Wavelength Service is the hallmark of optical technology. Based on Dense Wave Division Multiplexing (DWDM), this high speed transport solution for enterprises brings reliable access to those organizations needing very high bandwidths for storage, data center connectivity or massive file transfers. As with all its Optical solutions, AT&T produces this carrier-class service to meet its stringent standards and requires the components of the network to be standards based and thoroughly tested in our own labs.


A wide variety of custom configurations are available with Wavelength service. Voice, data, video or storage traffic can be supported. With this second generation technology, changes to the wavelength service can be reconfigured without taking down the service.

Options include:

  • Point-to-point or ring
  • 1.25 Gigabit to 10 Gigabit speeds
  • Up to 32 protected wavelengths on a single fiber

Interfaces available:

  • 1.25 Gbps, 2.5 Gbps
  • OC192, 10 Gbps WAN/LAN
  • 1 Gig
  • OC3, OC12, OC48
  • FICON Express
