Synchronous Optical Network

Highly reliable, secure nationwide data transport

CenturyLink® Synchronous Optical Network Service (SONET) provides dedicated duplex transmission connectivity between two or more designated end points, over which your Agency's service applications traverse at Agency-specified bandwidths. CenturyLink® SONET travels the CenturyLink four-fiber SONET Bi-directional Line-Switched Ring (4FBLSR) network to provide highly-reliable transport from DS-1 up through OC-48. Higher rate services are carried over the CenturyLink® Optical Wavelength transport network.

Features

  • Supports speeds of OC-3 through OC-48
  • Geography is all CONUS and Hawaii
  • Automatic protection switching
  • BLSR (Bi-directional Line Switched Ring)
  • Transmuxing from higher bandwidths to lower bandwidths and vice versa
