Add-drop Multiplexer
An add-drop multiplexer (ADM) is an important element of an optical fiber network. A multiplexer combines, or multiplexes, several lower-bandwidth streams of data into a single beam of light. An ''add-drop'' multiplexer also has the capability to ''add'' one or more lower-bandwidth signals to an existing high-bandwidth data stream, and at the same time can extract or ''drop'' other low-bandwidth signals, removing them from the stream and redirecting them to some other network path. This is used as a local "on-ramp" and "off-ramp" to the high-speed network. ADMs can be used both in long-haul core networks and in shorter-distance "metro" networks, although the former are much more expensive due to the difficulty of scaling the technology to the high data rates and dense wavelength division multiplexing (DWDM) used for long-haul communications. The main optical filtering technology used in add-drop multiplexers is the Fabry–Pérot etalon. Newer "multi-service SONET/SDH" (als ...

Dense Wavelength Division Multiplexing
In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. This technique enables bidirectional communications over a single strand of fiber, also called wavelength-division duplexing, as well as multiplication of capacity. The term WDM is commonly applied to an optical carrier, which is typically described by its wavelength, whereas frequency-division multiplexing typically applies to a radio carrier which is more often described by frequency. This is purely conventional because wavelength and frequency communicate the same information. Specifically, frequency (in Hertz, which is cycles per second) multiplied by wavelength (the physical length of one cycle) equals the velocity of the carrier wave. In a vacuum, this is the speed of light, usually denoted by the lowercase letter, c. In glass fiber, it is subs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
100 Gigabit Ethernet
40 Gigabit Ethernet (40GbE) and 100 Gigabit Ethernet (100GbE) are groups of computer networking technologies for transmitting Ethernet frames at rates of 40 and 100 gigabits per second (Gbit/s), respectively. These technologies offer significantly higher speeds than 10 Gigabit Ethernet. The technology was first defined by the IEEE 802.3ba-2010 standard and later by the 802.3bg-2011, 802.3bj-2014, 802.3bm-2015, and 802.3cd-2018 standards. The standards define numerous port types with different optical and electrical interfaces and different numbers of optical fiber strands per port. Short distances (e.g. 7 m) over twinaxial cable are supported while standards for fiber reach up to 80 km. Standards development On July 18, 2006, a call for interest for a High Speed Study Group (HSSG) to investigate new standards for high speed Ethernet was held at the IEEE 802.3 plenary meeting in San Diego. The first 802.3 HSSG study group meeting was held in September 2006. In June 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reconfigurable Optical Add-drop Multiplexer
In fiber optics, a reconfigurable optical add-drop multiplexer (ROADM) is a form of optical add-drop multiplexer that adds the ability to remotely switch traffic from a wavelength-division multiplexing (WDM) system at the wavelength layer. This is achieved through the use of a wavelength selective switching module. This allows individual or multiple wavelengths carrying data channels to be added and/or dropped from a transport fiber without the need to convert the signals on all of the WDM channels to electronic signals and back again to optical signals. The main advantages of the ROADM are: * The planning of entire bandwidth assignment need not be carried out during initial deployment of a system. The configuration can be done as and when required without affecting traffic already passing the ROADM. * ROADM allows for remote configuration and reconfiguration. * In ROADM, as it is not clear beforehand where a signal can be potentially routed, there is a necessity of power balancing o ...

Submarine Branching Unit
A submarine branching unit is a piece of equipment used in submarine telecommunications cable systems to allow the cable to split to serve more than one destination. For example, one branch might head for a cable landing point and others may continue. There are several methods by which the split can be affected, which can also depend on the type of cable system: * Purely electrical systems (now almost obsolete) can be split by either: ** Physically separating the signal cables so some go in one direction and some in another, which requires no additional power. ** Using an add-drop multiplexer to direct the signals down one path or the other. The electrical equipment that acts as the add-drop multiplexer will need powering. * Optical fibre cable systems can be split by either: ** Physically separating the signal-carrying fibres so some go in one direction and some in another, which requires no additional power. ** Converting the optically carried signals to electrical signals, using ...

Cable Landing Point
A cable landing point is the location where a submarine or other underwater cable makes landfall. The term is most often used for the landfall points of submarine telecommunications cables and submarine power cables. The landing will either be direct (in the case of a point-to-point cable system) or via a branch from a main cable using a submarine branching unit. The branch can be several kilometres long. Selection criteria Cable landing points are usually carefully chosen to be in areas: # that have little marine traffic to minimise the risk of cables being damaged by ship anchors and trawler operations; # with gently sloping, sandy or silty sea-floors so that the cable can be buried to minimise the chance of damage; # without strong currents that would uncover buried cables and potentially move cables. Such locations are rare, and will usually be the shared landfall point for several cable systems. Associated facilities Frequently, there will be a nearby cable landing ...
