Transmode extends passive WDM platform TG-Series to 52 channels

DECEMBER 8, 2009 -- Transmode, a provider of optical networking equipment, has expanded its TG-Series passive WDM platform by an additional 40 DWDM channels.

Transmode's TG-Series is a passive WDM platform that increases bandwidth capacity in metro access networks. It is in use by Tier 1 and 2 operators for applications such as local exchange/central office consolidation projects, fiber-to-the-curb/building for MSAN, and VDSL roll-out and high-security networks.

Through a range of terminal and add/drop multiplexer modules, the TG-Series supports point-to-point, mesh, bus-, and ring-based network topologies. The optical modules are available in different form factors, including rack-mounted modules for central offices and street cabinets. There are also modules for splice enclosures that are suitable for use in harsh environments like manholes.

To address the requirement for additional capacity in access networks, Transmode has now extended the number of available channels from 16 CWDM channels to an additional 40 DWDM channels. Hybrid configurations are also available with both CWDM and DWDM channels used to support applications requiring up to 52 channels, each carrying up to 10 Gbps. According to Transmode, the system can offer performance that is comparable to -- and, the company claims, better than -- WDM-PON and GPON in terms of number of channels and capacity.

TG-Series DWDM modules are available now and shipping to customer deployments.

"Recent TG-Series breakthrough sales wins have proven that the TG-Series has what it takes to differentiate itself against solutions from incumbent WDM suppliers," says Sten Nordell, Transmode's chief technology officer. "By adding DWDM filters, Transmode has taken a large step in providing unparalleled capacity in passive WDM networks and keeping the TG-Series at the forefront of access networking options."
