Net2EZ deploys Transmode for U.S. data center interconnect
Optical transport systems developer Transmode says that Net2EZ, a US-based managed data center service provider, has upgraded its high-speed optical network using Transmode's TM-Series and TG-Series optical networking platforms.Net2EZ replaced its existing DWDM equipment with Transmode's platforms to increase the capacity of its network, Transmode says. The new protected fiber ring is designed to offer uninterrupted service to seven data centers across the United States with multiple 10G and 1G connections. At the same time, Net2EZ has added three new data centers to the network. Net2EZ plans to replicate this network architecture as they continue their expansion across the US.The network uses the TM-Series 10G transponders with forward error correction for long-haul transmission and also has redundant fiber paths for network protection.The upgrade also improves Net2EZ’s network management capabilities that enable it to identify and resolve issues remotely. The redundancy built into the infrastructure enables Net2EZ to keep the network running while performing maintenance."We have redundant fiber between our buildings and with the Transmode solution we were able to get better diagnostics and increased performance,” said Daniel Faubel, director of network engineering at Net2EZ. “We can now tell if we are having problems without actually having to unplug the fiber, and run a fiber tester to figure it out and can access our Virginia network remotely from Los Angeles."
Cable&Wireless Worldwide chooses Ciena for 100-Gbps link
Cable&Wireless Worldwide ((LSE: CW; CWW) has chosen the 6500 Packet-Optical Platform from Ciena Corp. (NASDAQ: CIEN) to power a 100-Gbps link between London and Monaco, Ciena says. The 2,800-km route will be the longest 100-Gbps deployment on the continent, the company asserts.The link will also connect with Milan, Frankfurt, Dusseldorf, and Amsterdam. The 100-Gbps technology is being added to an existing CWW network that currently supports 40-Gbps data rates using Ciena technology as well.Increasing bandwidth demands drove CWW to the network upgrade, including an anticipated traffic surge from CWW’s role in the Europe India Gateway (EIG) undersea cable system (see “Africa, Middle East see boost in submarine capacity”).“The explosive demand for capacity promises to continue as the number of public and private network connections increases for consumers and businesses and as these connections support bandwidth-intensive applications such as video and remote storage,” says John Paul Hemingway, EMEA vice president of strategic development at Ciena. “A long-term Ciena partner, Cable&Wireless Worldwide is making a highly progressive move in Europe with the region’s longest coherent 100G link, which forms the basis for a resilient, scalable, and flexible backbone network.”
Finisar unveils Flexgrid wavelength-selective switches for next-gen ROADMs
SEPTEMBER 7, 2010 -- Finisar Corp. (NASDAQ: FNSR) has introduced its new Flexgrid wavelength-selective switch (WSS) technology. Flexgrid is designed to enable dynamic control of channel center frequency and channel bandwidth within a WSS, from 50 GHz to 200 GHz in 12.5-GHz steps, with no penalty on any aspect of WSS performance.Finisar says Flexgrid draws upon the inherent flexibility and performance of the company's Liquid Crystal on Silicon (LCoS) optical engine to address carrier demand for flexible, bandwidth-capable ROADMs in next-generation networks.The need for increased network capacity, efficiency, and flexibility is driving the introduction of higher data rates, new transmission formats, and channel management technologies. These all require flexible bandwidth capable ROADMs, says Finisar. For example, the introduction of coherent techniques enables 100-Gbps transmission within a 50-GHz channel. However, higher speed traffic, including future 400-Gbps and 1-Tbps signals, will not fit into such a narrow channel, Finisar asserts. To maximize network capacity and future-proof a carrier's investment in transmission hardware, the channel bandwidth in both the WSS and the add/drop components required for contentionless, directionless, colorless (CDC) architectures must therefore be dynamically variable to accommodate new transmission formats and data rates, Finisar contends."Channel-width flexibility is increasingly sought by major telecom carriers as a way to maximize bandwidth-efficiency in the network," said Andrew Schmitt, senior analyst with Infonetics Research. "Flexible Grid functionality offered by leading suppliers, like Finisar, allows an optical network to accommodate advanced optical transmission techniques."
