Charter Business Ethernet & Optical Transport
Charter Business combines abundant metro fiber in 21 states with a solid, if unsophisticated,portfolio of Ethernet and optical transportservices. But the fourth-largest cable operator is struggling to service its massive $21 billion debt. (1/21/2009)

Cox Business Services Ethernet & Optical Transport
Cox Business' metro area business services are competitive and include Ethernet private line, E-LAN, SONET, and wavelengths, but its services are limited to scattered clusters of cable systems. (1/21/2009)

Optimum Lightpath Ethernet & Optical Transport
Optimum Lightpath offers Ethernet, SONET and wavelength services in the NYC metro area. Lightpath’s Ethernet portfolio includes converged voice, data and video, but its all-optical footprint does not extend far beyond the tri-state NYC region. (1/21/2009)

Suddenlink Ethernet Metro Ethernet & Optical Transport
Suddenlink offers local and long haul Ethernet and optical transport services in nearly 1,000 localities across 16 states. However,its footprint is comprised of mostly small townswith limited demand for high-bandwidth business services. (1/21/2009)

Time Warner Cable Business Services Business Class Ethernet, Metro Ethernet & Optical Transport
TWCBC services include Ethernet E-LINE and E-LAN services as well as optical Internet access, and the company recently began rolling out Ethernet over HFC, although its services are limited to metro area islands without any long haul capability (1/20/2009)
