An optical cross-connect (OXC) is a device used by telecommunications carriers to switch high-speed optical signals in a fiber optic network, such as an optical mesh network. In the 1980s, when transmission speeds supported by optical fibers increased from 45 Mbit/s to 2.5 Gbit/s , carrier networks developed and introduced digital cross ...
Optical fiber connectors are used in telephone exchanges, for customer premises wiring, and in outside plant applications to connect equipment and fiber-optic cables, or to cross-connect cables. Most optical fiber connectors are spring-loaded, so the fiber faces are pressed together when the connectors are mated.
Switching, multiplexing, and grooming of traffic in an OEO device. Optical mesh networks refer to transport networks that are built directly off the mesh-like fiber infrastructure deployed in metropolitan, regional, national, or international (e.g., trans-oceanic) areas by deploying optical transport equipment that is capable of switching traffic (at the wavelength or sub-wavelength level ...
LAN-to-LAN connections on campuses at Fast Ethernet or Gigabit Ethernet speeds; LAN-to-LAN connections in a city, a metropolitan area network; To cross a public road or other barriers which the sender and receiver do not own; Speedy service delivery of high-bandwidth access to optical fiber networks; Converged voice-data connection
Recent digital cross connect systems (DCSs or DXCs) support numerous high-speed signals, and allow for cross-connection of DS1s, DS3s and even STS-3s/12c and so on, from any input to any output. Advanced DCSs can support numerous subtending rings simultaneously.
In integrated circuits, optical interconnects refers to any system of transmitting signals from one part of an integrated circuit to another using light. Optical interconnects have been the topic of study due to the high latency and power consumption incurred by conventional metal interconnects in transmitting electrical signals over long distances, such as in interconnects classed as global ...
Wavelength switched optical network (WSON) is a type of telecommunications network. A WSON consists of two planes: the data and the control planes. The data plane comprises wavelength-division multiplexing (WDM) fiber links connecting optical cross-connect (OXCs) through a comb of several tens of wavelength channels, with typical data rates of ...
Traffic grooming is the process of grouping many small telecommunications flows into larger units, which can be processed as single entities. For example, in a network using both time-division multiplexing (TDM) and wavelength-division multiplexing (WDM), two flows which are destined for a common node can be placed on the same wavelength, allowing them to be dropped by a single optical add ...
