London's TfL selects Transmode CWDM for SAN/MAN upgrade

June 30, 2005 Stockholm, Sweden -- Transport for London (TfL) has selected Transmode to provide a CWDM platform to expand and improve TfL's metropolitan and storage networks, which underpin the management of London's public transport services. TfL has selected the company's TS-1100 platform to expand the capacity of its data-transport network and to improve data-traffic management.

TfL says it selected the platform to support two key applications: expanding the Fibre Channel capabilities of the organization's SAN, and increasing the availability of Gigabit Ethernet channels for the organization's MAN.

Transmode says the platform's installation is based primarily on its 5400 Universal Aggregator card, which carries multiple Fibre Channel or Gigabit Ethernet signals over a WDM network. The company says the card multiplexes two Fibre Channel or Gigabit Ethernet interfaces into a single CWDM wavelength in a highly efficient manner. This then allows full utilization of available fiber capacity while eliminating stranded bandwidth across the network, according to the company.

"Since we started installing the TfL system in September 2004, there has been a process of continuous upgrade," comments Sean Davies, Transmode's UK Sales Manager. "TfL has now deployed multiple wavelengths across its SAN and MAN, and we are further developing the client's networks to be even more flexible and easily expanded as traffic increases."
