The 100G trial will run for the week of March 9th spanning the Comcast infrastructure from Philadelphia, PA to McLean, VA traversing Comcast’s metro and long-haul fibers. More than 1,200 of the world’s top Internet engineers attending the IETF meeting are expected to make use of this high-speed network to access the Internet. The 100G solution runs over Comcast’s existing fiber network. The test network is comprised of Comcast’s existing Common Photonic Layer DWDM solution with 50GHz enhanced Reconfigurable Optical Add/Drop Multiplexer (eROADM) and photonic components, augmented with prototype 100G interfaces installed in Nortel’s Optical Multiservice Edge 6500. The 100G cards utilize Nortel’s 40G/100G Adaptive Optical Engine, with integrated dispersion compensation and dual-polarization Quadrature Phase Shift Keying (QPSK) modulation, the same technology used in Nortel’s present 40G solution.
