JUNE 12, 2007 -- OpVista (search for OpVista) has announced EtherWave, designed to lower the cost of aggregating Gigabit Ethernet (GbE) traffic streams into a cost-effective 10GbE handoff on metro and regional backbone networks. EtherWave will debut next week in live network simulations at the NXTComm and SCTE Cable Tec Expo conferences and exhibitions in Chicago and Orlando, respectively.
EtherWave is generally available and will ship to customers in July 2007.
The EtherWave offering, consisting of the OpVista2000 TR-110 GbE muxponder and the TR-71 10GbE transponder and incorporating Layer 2 functionality, represents an important addition to OpVista's nWave architecture for Carrier Ethernet transport network infrastructure.
In today's environment, carriers can devote a fiber for each new application carried over a GbE connection, but the operations and management associated with this practice becomes expensive and exhausts valuable fiber plant. An alternative involves multiplexing the individual multiple GbE streams carrying different applications into a single 10-Gbit/sec pipe for transport across the network. At the edge, operators must then install a router to demultiplex the 10-Gbit/sec pipe into its individual GbE streams. This approach also has proven expensive and has added unnecessary complexity into network management. Incorporating DWDM to boost the capacity of each fiber solves the first "fiber centric" problem, but does not eliminate the need for a router at the edge of the network.
The EtherWave approach is designed to meet the increasingly important network requirements for Ethernet architectural and operational efficiency by combining 10GbE client-side signals into one 10-Gbit/sec ITU-compliant DWDM wavelength on the network side. OpVista can then handoff a 10GbE signal to a router located in a central office or hub node facility, with the individual GbE streams tagged separately to allow distribution to the appropriate service. This aggregation and segregation eliminates the need for an edge router, OpVista asserts.
"As competition for business customers intensifies, operators are looking for ways to improve their time to market and reduce capex and opex costs. The EtherWave solution continues OpVista's leadership in infrastructure reuse and capex and opex reduction by providing Layer 2 functionality to tag the individual GbE streams for distribution, thus eliminating some network elements normally required. As a result, OpVista's EtherWave solution delivers a large cost savings as well as lowering opex in the network, showing that they are one of most cost-effective solutions in this metro space," said Eve Griliches, program manager, telecom equipment of IDC.
