The explosion of video traffic has dictated new requirements on the network. Meanwhile, enterprise Local Area Networks are now being interconnected over 10-Gbps Ethernet interfaces and carriers' routers are now equipped with 40-Gbps interfaces, thus increasing the transport network's bandwidth capacity becomes more imperative than ever.
While many options are available to increase network capacity, very few allow achieving this task without re-engineering the network or the need for massive capital investment.
Leveraging Nortel's Dual Polarized QPSK with eDCO technology allows service providers and network operators to quadruple network capacity while leveraging existing assets and maintaining current planning/operation processes.
