Crosswave uses synchronous optical network (sonet) and wavelength division multiplexing (dwdm) technologies, which enable it to transmit data at high speeds over long distances with a high degree of reliability.

FORBES: 20 FOR 2000

Worldcom was one of the first carriers to deploy a newfangled technology called "dense wavelength division multiplexing" (FORBES, Oct. 7, 1997) that greatly increases the amount of traffic an existing fiber-optic cable can carry.
