Transport for all payloads, with superior performance and support for dynamic services with operational efficiencies. The advantages provided by optical fiber systems are the result of a continuous stream of product innovations and process improvements. Optical transport equipment includes multiplexers of all types amplifiers, cross connects, and others, including the emerging packet optical transport platforms. Packet transport networks take advantage of a variety of technologies. Carrier Ethernet switches, packet optical transport systems, IP switches and routers, and label switched router platforms are some of the technologies carriers have employed in packet transport networks for mobile backhaul, video transmission, data services, and other digital services.
