Synchronous Optical Network (SONET)
|
Synchronous optical network (SONET) is a high-speed, synchronous network designed to run on fiber at digital transmission rates from 51.84 Mbps to beyond 2.4 Gbps. SONET is a family of fiber optic transmission rates and optical interface standards that enables users to connect products from different vendors. SONET defines a physical-interface optical line rate known as optical carrier (OC). It also defines the frame format and an operating, administration, maintenance, and provisioning (OAM&P) protocol.

Network switches route packets between ports at the OSI layer 2, which means that (in Ethernet) the switches decide where incoming packets are transferred to, based on the NIC's 48-bit address.

Network routers are protocol-dependent devices that connect subnetworks. They are also used to break down a large network into smaller subnetworks.

Networking repeaters regenerate incoming electrical, wireless or optical signals to preserve signal integrity and extend the distance over which data can travel. They are often used to connect cable segments in IEEE 802.3 networks.
