Glossary
I have included here a few of the most commonly used T1 and Network Cabling keywords. For an in depth list. Just use one of the blue links.
Cat 3 Cable: The Cat 3 Cable is a UTP (Unshielded Twisted Pair) cable, which reliably carries up to 10 Mbit/s of data. It has a possible bandwidth of 16Mhz. Cat 3 is still mostly in use in two-line telephone systems, but has been mostly superceded by the higher performing Cat 5 standard.
Cat 5 Cable: The Cat 5 Cable is a twisted pair cable, mostly unshielded (but there are shielded types.) It is designed for high signal integrity, and can carry up to 155 Mbit/s over short distances. It is used mostly for Ethernet networks, basic voice services and ATM's, but has been superceded on many industries by the Category 5e specification.
Cat 5e Cable: The Cat 5e cable is an enhanced Cat 5 cable, with added specifications for far end crosswalk. With its tighter specifications, it is an excellent choice for 1000BASE-T.
Cat 6 Cable: The Cat 6 cable is standard for Gigabit Ethernet and similar network protocols. It is backward compatible with the Category 5 and Category 5e standards. The Cat 6 cable standard delivers a bandwidth of up to 250Mhz. The Cat 6 cable is more effective for system noise and crosstalk.
Coaxial Cable: Coaxial Cable is an electrical cable, and consists of a round counducting wire covered by an insulating spacer, which is covered by a cylindrical conducting sheath, lastly covered by a final insulating layer. It is used for high-frequency transmissions and broadband.
Structured Cabling: The term “Structured Cabling” refers to a cabling infrastructure for a building or campus. It consists of many smaller elements, all standardized according to a specification. These are called subsystems.
Plenum Cabling: The term “Plenum Cabling” refers to structured cabling laid in the plenum of buildings (the space where air circulation – heating and air conditioning systems – are facilitated.) It has a slow-burning, fire-resistant casing.
Non-Plenum: Non-Plenum refers to structured cabling that run between floors (non-plenum areas), and rated more as riser cable.
Fiber Cabling: Fiber Cabling is the term used to refer to structured cabling using the Fiber Optic standard.
Fiber Optics: Fiber Optics is a loose term that refers to both the applied science and engineering fields that overlap in structuring fiber optic systems using optical fiber. Optical Fiber is very thin plastic or glass fiber wire, made from incredibly pure optical glass, designed to use light to carry digital signals.
Network Cabling: Network Cabling is a broad term referring to network or ethernet structures or cabling, for a building, office or campus.
RJ 45: The RJ-45 is the standard connector used for Ethernet, T1, ISDN, or 4-pair UTP cables.
RJ 11: RJ-11 is the standard connector used for 2-pair (4 wire) telephone wiring. It comes in both UTP or untwisted cable.
Ethernet: An Ethernet refers to the various computer networking technologies for a Local Area Network (LAN.)
LAN: LAN stands for Local Area Network and refers to a computer network for a small area, such as an office, home or group of buildings.
WAN: WAN stands for Wide area Network and refers to a computer network that covers a broad area, where communications can cross national, regional or metropolitan boundaries.
MEGABYTE: A unit for measuring computer memory or data storage. A unit of information equal to 1000 kilobytes.
GIGABYTE: A unit for measuring computer memory or data storage. A unit of information equal to 1000 megabytes.
TERABYTE: A unit for measuring computer memory or data storage. A unit of information equal to 1000 gigabytes.
