Optical Systems

Optical systems are the combination of optical equipment, protocols and transmission lines that are used to provide communication services. Some of the common types of optical systems include synchronous optical network (SONET), synchronous digital hierarchy (SDH), fiber distributed data interface (FDDI), passive optical networks, fibre channel, wave division multiplexing (WDM), resilient packet ring and optical Ethernet.

The high capacity of fiber systems and low relative cost of fiber bandwidth capacity has resulted in the integration (collapsing) of edge network components with the core of the network. A collapsed backbone method of interconnecting networks by using a switch or router as a central relay device rather than using multiple switching or concentration points.
