During the recent exhibition CommunicAsia 2002 which took place in Singapore last June, Corning Inc., USA, and Nortel Networks, Canada, have demonstrated an integrated, total network solution to meet the challenges of today's carriers' high-bit rate, metropolitan networks. Utilising Corning� LEAF� optical fibre operating in the metro core at 10Gbit/s over the Nortel Networks OPTera™ Metro 5200 system, the demonstration exhibited a significant uncompensated reach advantage in today's metropolitan core architectures. Additionally, in moderate bit-rate, unamplified, metro edge systems, Corning� SMF-28e™ fibre, operating over Nortel Networks OPTera™ Metro 5100 system at 1.25Gbit/s for 50km demonstrated a versatile, flexible, scalable network architecture. Various portions of the network demonstration used Agilent's testing and monitoring equipment, which provides the carrier with technically optimised, cost-effective solution. "By co-ordinating efforts with companies such as Corning and Agilent, we continue to realise further technological advances in optical communications and bring high-performance, dependable, cost-efficient solutions to our customers", commented Mr James Demers, vice-president, optical Internet Asia, Nortel Networks. "The integration of LEAF and SMF-28e fibres with their innovative metro core and metro edge products results in technologically advanced solutions, which deliver greater network flexibility, enhanced capabilities and cost-savings to the customer", added Mr Michael Perry-Jones, senior manager, Corning Inc.
Nortel Networks OPTera™ Metro 5200 is protocol and bit-rate independent and dense wavelength division multiplexing data-optimised. It includes a survivable platform with tributary interfaces for metropolitan access and interoffice applications. OPTera™ Metro 5200 uses DWDM to optimise current fibre infrastructure and also provides flexible connectivity over point-to-point or ring-based networks. Nortel Networks Metro 5100 Multiservice platform provides the capability to network services across an open, scaleable survivable WDM optical transport platform. Equipped with a bit rate provisionable universal optical interface, the OPTera Metro 5100 can network these services through a single interface.
Corning� LEAF� fibre is the world’s most advanced non-zero, dispersion-shifted fibre (NZ-DSF), featuring a large effective area to allow higher levels of power to be transmitted through the fibre than standard NZ-DSFs, and minimising the non-linear effects that degrade system performance. SMF-28e fibre, an extension of Corning's standard single-mode product line, boasts superior low water peak performance with specified performance covering a broad operating spectrum from 1,285 to 1,625nm.
