Ciena Proposes Optical Network Architecture with 2 Tb/s Core
Linthicum, MD-based Ciena Corp. is rolling out its complete intelligent optical network architecture including a new 2 Tb/s transport platform called LightWorks at Supercomm '99 in booth 7739 in the Georgia World Congress Center, Atlanta, from June 7-10, 1999.
In conjunction with the networking blueprint, Ciena is revealing plans for Multiwave CoreStream, a new long-haul dense wavelength division multiplexing (DWDM) optical transport platform that will accommodate incremental capacity upgrades up to 2 Tb/s over a single fiber pair. Each channel can be any mix of OC-12/STM-4, OC-48/STM-16 or OC-192/STM-64 optical interfaces.
CoreStream's network management capability enables network operators to maintain and monitor all of their CoreStream elements from a single console. Software also automates system operations within each CoreStream element. Optical channels can be added without service disruption. Each optical channel features digital performance monitoring which helps a carrier meet service level agreements and troubleshoot network problems.
New broadband optical amplifiers enable flexible bandwidth commissioning long-distance span design, and an optical add/drop multiplexer that accesses up to eight channels in the middle of DWDM spans. The initial release of the MultiWave CoreStream will be capable of 480 Gb/s of transport capacity and is expected to be commercially available in September 1999. The second release, expected to be available in mid 2000, will expand the transport capacity to 2 terabits.
The LightWorks architecture offers to service providers integrated capabilities in optical transport, optical core switching, automated provisioning and grooming, multi-service access, and flexible survivability options. LightWorks also presents a roadmap for carriers with large and complex networks to efficiently integrate SONET/SDH, long and short-haul DWDM, ATM, and IP while preparing to deliver new services.
Products to be demonstrated in live network applications in Ciena's main booth include MultiWave Sentry 4000, MultiWave Metro, MultiWave CoreStream, MultiWave CoreDirector, WaveWatcher, Omnia Communication's AXR-500, and the Cisco GSR 12000.
