MCI, working in collaboration with CIENA and Mintera Corp., established a 40 Gbps connection across a long haul route spanning 1,200 km. The technology trial took place over MCI's ultra long haul DWDM route between Sacramento, California and Salt Lake City, Utah. This network route was selected because it uses the company's existing fiber plant, and includes a mix of fiber -- TrueWave Classic, Dispersion Shifted Fiber (DSF), Long Span Fiber (LS) and Single Mode Fiber (SMF). Mintera's 40 Gbps DWDM fiber optic transport terminals interoperated directly on CIENA's CoreStream Agility optical transport system, which provides an automated ULH backbone for the MCI network. The companies said the 40 Gbps wavelength was commissioned in less than an hour, and then performed error-free on the same optical fibers already carrying 10 Gbps wavelengths throughout the trial. http://www.mci.com/http://www.mintera.com/
