Nortel Networks builds first Japanese campus optical network

Aug. 30, 2001--The University of Tsukuba has selected Nortel Networks to build what is expected to be the first university optical network in Japan based on dense wavelength division multiplexing.

The University of Tsukuba has selected Nortel Networks (NYSE/TSE: NT) to build what is expected to be the first university optical network in Japan based on dense wavelength division multiplexing (DWDM). Construction and testing are already underway, with network operations scheduled to begin in September.

Used primarily for inter-city and metropolitan areas networks, DWDM expands the transmission capacity per wavelength of optical networks. The University of Tsukuba network will feature DWDM at the campus level, providing significantly increased capacity over traditional, local area network solutions and positioning the University to address anticipated future demand for bandwidth-intensive data applications.

Nortel Networks' solution for the University of Tsukuba will include Nortel Networks OPTera Metro 5200 Multiservice Platform and Nortel Networks Passport 8600, a carrier-grade routing switch to support Gigabit Ethernet capability.

Nortel Networks OPTera Metro 5200 is protocol and bit-rate independent and DWDM data-optimized. It includes a survivable platform with tributary interfaces for metro access and interoffice applications. OPTera Metro 5200 integrates ATM, FDDI, Fiber Channel and other networks typically deployed by educational institutions, enabling migration to ultra high-speed networks. It can multiplex 10 gigabits per second per wavelength for up to 32 wavelengths, with a maximum transmission distance of approximately 120 kilometers.

Nortel Networks Passport 8600, a carrier-grade routing switch based on ASIC technology that supports Gigabit Ethernet, provides high-quality transmission for a variety of multimedia applications, including e-learning, video, Voice over IP, and high-capacity file transfer.
