WDM has already played an important role in aggregation of cell traffic, but in the past was seldom used to provide bandwidth to the cell site itself. But now a highly competitive and comprehensive WDM-based solution that offers scalability, flrxibility and cost optimization of bakhaul requirements ranging from the cell site through aggregation and metro transport network is available.

Native Ethernet and TDM traffic, with support for multiple individually synchronized domains delivered over a single wavelength that stretches all the way to the base station. Is this possible? Yes - and at unprecedented low cost!

With an explosion for high capacity packet based services, driven by
residential usage such as video streaming, voice over IP and gaming,
coupled with business requirements for flexible VPN’s and high capacity
backhaul services. A converged packet / WDM network enables the
seamless delivery and huge scalability required to support the growing
bandwidth demands of the future network.

A converged packet optical transport network based on Intelligent WDM
(iWDM™) enables network operators to develop cost effective strategies
that service the growing demand for wavelength and packet based
services, while maintaining support for profitable TDM based SDH &
SONET services. Flattening the network to a single layer will simplify the
network, resulting in a reduced unit cost of delivering traffic across the
network thus significantly reducing the total cost of ownership.

With developments in Ethernet technologies, providing feature rich
OAM&P, supporting connection orientated Ethernet services, while
leveraging the benefits of Layer 2 statistical gain, bandwidth re-use and
oversubscription, network operators now have the capability to unleash
the latent capacity within the network while maintaining the assurance
that performance levels will be maintained in line with existing SDH &
SONET networks.

The demand for Carrier Ethernet is growing quickly with a CAGR in the range of 50% as operators make the shift from legacy services to Carrier Ethernet services as part of their transition to converged multi-service-networks. Infonetics Research Inc. has estimated the worldwide market for Carrier Ethernet services to grow from $2.5 billion to more than $22 billion in 2009...
