(Telecompaper) Facebook has developed a new optical packet transport architecture that it plans to contribute to the open-source Telecom Infra Project. The new approach called Open Packet DWDM uses combined packet and dense wavelength division multiplexing (DWDM) technology for metro and long-haul fibre-optic transport networks. Facebook has used Open Packet DWDM to develop a new transponder platform called Voyager and is working with companies such as Adva, Coriant and Equinix to test the platform.
