Philadelphia--Comcast said it successfully completed a 100 Gigabit Ethernet technology test over its existing backbone infrastructure between Philadelphia and McLean, Va., using the industry’s first 100-GE router interface developed for Cisco Systems' CRS-1 routing system.
Earlier this year Comcast touted a similar test -- over the same fiber route -- using Nortel Networks 100-Gbps interface cards in the vendor’s Optical Multiservice Edge 6500 system.
The Cisco CRS-1 100GE interface uses Comcast’s existing optical infrastructure to enable transmission of 100GE over DWDM fiber-optic networks.
According to Comcast, the technology will allow it to increase bandwidth per wavelength 10 times over the initial deployed capacity.
“This demonstration is another important step in the future of 100GE networking and we’re pleased with Cisco’s latest advancements,” John Schanz, Comcast executive vice president of national engineering and technical operations said, in a statement.
