Description
Summary:When it came to upgrading its transport network, Texas A&M University looked beyond established vendors of WDM equipment. With 45,000 students, a growing Web-based curriculum as well as an increasing requirement for videoconferencing, it was apparent that the school's capacity needs would make deploying more SONET rings an expensive transport solution. Verizon, with full support of the university's IT officials, decided to go ahead with the first commercial deployment of the V32000 Optical Distribution System from Photuris. The platform is a ROADM (reconfigurable optical add/drop mux) for metro core and regional applications that also, via its ADM-on-a-wavelength line card technology, offers OC-3 through OC-192 SONET services, with the capability of muxing lower-speed circuits onto OC-48/192 channels. The two-fiber V32000 system supports up to 32 protected wavelengths (which can be a combination of 2.5- and 10-Gbps). A Photuris network can expand to a 16-node-ring with a circumference of 600-km-without electrical regeneration-and with span distances of up to 100 km. The integration of SONET ADM and WDM technologies eliminates the need for ADM farms or stacked rings and also obviates the fiber exhaust issue.
