- Adapter - Mechanical element making it possible to make a connection between two plugs.
- Backbone - Network section with the highest traffic load.
- Cabinet (distribution) - Closed space containing all communication equipment, cable connections.
- Cable to pair - Cable with one or more metallic cable elements, which may be symmetrical (twisted paired or other) or symmetrical reinforced or not reinforced.
- Cabling - Set of cables, wires, patch, fibers and material connection.
- Cleaver - Tool to break the fiber (to cleave) and preparer the weld.
- Concentrated cabling - Cabling architecture between the access point in the workspace and the centralized building distributor.
- Connection cabinet - Box for connecting communication cables, distribution and connection equipment, with a swinging lid.
- Connection patch - Cable connecting the plug to the terminal (sometimes referred to as a patchcord).
- Dispenser - Structure equipped with terminations intended to connect the cables of an installation so that the interconnections and distributions can be easily realized.
- Distribution cable - Cable connecting the access point to the connection socket.
- Distribution link - Section of the permanent link between the floor dispatcher and the access point.
- DTI "Inside Termination Device" - Box serving as a border between the France Telecom network and the customer's telephone network. This box, also known as Terminal or Subscriber Box, is installed in the home of the subscriber.
- DTI-O : "Optical Inside Termination Device" - This is the optical version DTI.
- ETSI - "European Telecommunications Standards Institute", European standardization body in the field of telecommunications. 19" contra bay standard.
- Ferule - End of a connector inside which the fiber is located.
- FTTH - "Fiber To The Home" : a physical telecommunications network that notably allows very high-speed internet access and in which the optical fiber ends at the subscriber's home.
- FTTO - "Fiber To The Office" : privileged by small businesses, SMEs and communities whose connectivity is essential in the smooth running of their business to access for example remote services that are greedy.
- IK - The IK index determines the degree of protection of the equipment against mechanical shocks. (examples : IK08, IK09, etc...)
- IL - Insertion Loss
- LAN - Network with limited right-of-way (from a few hundred meters to a few kilometers).
- MAN - "Metropolitan Area Network" refers to a network of computers usually used in campuses or in cities. The network generally uses fiber optics.
- NRA - Subscriber connection node (Nœud de Raccordement Abonnés).
- NRO - Optical connection node (Nœud de Raccordement Optique).
- Optical Fiber - Optical fiber is a very thin glass or plastic cable whose has the property of driving light. Several types of optical fibers are currently used in networks : singlemode or multimode.
- Pair - It's the two conductors of a symmetrical transmission line. Usually refers to a twisted pair or part of the circuit.
- Patch - Cable equipped with plug, allowing to connect the telecommunications equipments, the active products and to carry out the brewings in the distributors.
- Patch panel - Coupling connector distribution system for easy connection management.
- Patchcord - Cable or cord without connector used for connection to a splitter box.
- Path of cables - Element hosting the telecommunication cables.
- Pigtail - Fiber of 900µm of a few meters, preconnectorized at one end and intended to be connected at the other end by a splice.
- Reflectometer - Measuring device for verifying that an optical transmission line is mismatched (measurement of optical budget, length, reflection).
- Rising column - The cables leaving this column link the different floors in muffs, sheaths or pipes. Each cabinet is usually equipped with hardware necessary to maintain the cables and a compartmentalization system.
- Splice - Connection of transmission media (copper or fiber).
- Splice box - Housing enclosing a splice.
- SSC (CAD) - SelfStriping Connection
- Street cabinet - Zone where the cables of the building are connected and interconnected.
- Switch - Device used in computer networks and particularly in the field of simple and multiple wireless selection.
- TGBT - (Tableau Général Basse Tension) This is the low voltage electrical panel of large electrical installations. This table is the link between the supplier (as EDF in France) and the customer network (company, individual ...).
- UMS - Universal Mounting System
- Weakening - Decrease of the intensify signal between two points. The weakening is usually expressed in the form of a ratio between the output power and the input power. It is measured in decibels (dB).
