What is Coaxial cable?
Coaxial cable is a type of communication transmission cable in which a solid center conductor is surrounded by an insulating spacer which in turn is surrounded by a tubular outer conductor (usually a braid, foil or both). The entire assembly is then covered with an insulating and protective outer layer. Coaxial cables have a wide bandwidth and are capable of carrying many data, voice, and video conversations simultaneously. There are several types of coaxial cabling:
- Thicknet is the 50-ohm "thick" (10mm) coaxial cable used with Ethernet 10Base5 networks. 10Base5 is the original Ethernet system that supports a 10 Mb/s transmission rate over a 500 meter maximum supported segment length.
- Thinnet is the 50-ohm "thin" (5mm) coaxial cable used with Ethernet 10Base2 networks. 10Base2, also known as "Thin Ethernet", or "cheapernet", supports a 10 Mb/s transmission rate over a 185 meter maximum supported segment length.
- CATV cabling is the 75 ohm coaxial cabling commonly known for its use in transmission of Cable TV signals, but is also used with Ethernet 10Broad36 networks. CATV stands for "community antenna television"
What suppliers do you typically work with?
We work with a number of the leading providers of commercial and industrial audio, video, cabling, networking, and control systems equipment.
What does ATM mean?
Asynchronous Transfer Mode (ATM) is a form of very fast packet switching in which data is carried in fixed length units called "cells". Each cell is 53 bytes in length, with 5 bytes used as a header in each cell. ATM employs mechanisms that can be used to set up virtual circuits between users, in which a pair of users appear to have a dedicated circuit between them. ATM is defined in specifications from the ITU and ATM Forum. Asynchronous Transfer Mode (ATM) is also the technology selected by the International Telecommunications Union (ITU, formerly CCITT) for broadband ISDN. This communications protocol is also specified by The ATM Forum (Foster City, CA) for 155 Mb/s transmission over twisted-pair cable and various bit rate optical fiber cabling applications.
What is Structured Wiring?
Structured Wiring is a methodology of telecommunications cabling that is organized into a hierarchy of wiring termination and interconnection structures. The concept of structured wiring is used in the common standards from the TIA and EIA.
