Packet-optical transport is now widely used by carriers across their networks. It brings the advantages of Sonet/SDH (synchronous digital hierarchy), dense wavelength division multiplexing (DWDM) and packet-based networks, delivering a scalable and resilient transport infrastructure. Packet-optical transport is used in the core of the network providing a highly reliable long distance connection, in the metro providing a high bandwidth and resilient network and at the edge delivering carrier grade services to enterprises. The report details and analyzes integrated packet-optical devices and OTN framer/mapper devices and technologies, identifying the key requirements and the highlighting the advantages they hold for equipment manufacturers. It also surveys component availability, reviewing features, performance and flexibility. The report covers more than 50 devices and profiles nine vendors in this important market.
