Serial Cable Assemblies Specifications

Cable Construction


	Cable Type:
	Your choices are...
	Cat 3		Standards for Category 3 - 100 ohm twisted-pair copper cable that meets or exceeds specifications in ANSI / TIA / EIA-568-A, Commercial Building Telecommunications Cabling Standard, and ISO /I EC 11801, Generic Cabling for Customer Premises for transmissions up to 16 MHz.
	Cat 5		A cabling standard for UTP wiring offering speeds up to 100 MHz and a data transfer rate up to 100 Mbps. This is the most popular UTP wiring standard and most often used in Ethernet networking of 10BaseT or 100BaseT.
	Cat 6		Standards for Category 6 - 100 ohm twisted-pair are still under review. Recent developments include work started on the Category 6 cabling specification. Many debates also include the issue of a high-temperature environment for Cat 6 cabling.
	Coaxial		Coaxial cable consists of two cylindrical conductors with a common axis. The two conductors are separated by a dielectric. The outer conductor, normally at ground-potential, acts as a return path for current flowing through the center conductor and prevents energy radiation from the cable. The outer conductor, or shield, is also commonly used to prevent external radiation from affecting the current flowing in the inner conductor. The outer shield or conductor consists of woven strands of wire or is a metal sheath.
	Fiber Optic		Fiber optic cable offers up the possibility of near infinite bandwidth and perfect immunity to noise. The trade-off is cost and difficulty of installation. It costs significantly more to purchase fiber optic cable, connectors, patch panels, jumper cables, tools, and network interface cards (NICs).
	RG6/11		This is an inexpensive, quarter-inch diameter unbalanced coaxial cable consisting of a central metallic core surrounded by a layer of insulating material. This insulating (dielectric) material may be a solid material or air spaced. The entire assembly is covered with a metallic sleeve and protected by an outer layer of non-conducting material (cable jacket). RG6 is typically used in cable TV or satellite applications. RG11 is the cable type used with thicknet (thick Ethernet) cabling.
	Triaxial		Triaxial cables refer to a three-conductor cable with one conductor in the center. A second circular conductor shield shares a common center with the first. There is a third circular conductor shield that is insulated from and is concentric with the first and second. Concentricity is usually with insulation, a braid, or impervious sheath overall.
	Type 1		Type 1 is a specification and standard for networking cable, usually used in Token Ring networks.
	Twisted Pair		A twisted pair is two wires twisted together to reduce susceptibility to RF noise. Two insulated copper conductors are wound around each other to cancel the effects of electrical noise. Twisted pairs are used as a popular and low-cost LAN cabling method that is also commonly used for telephone wiring. This method uses tow wires twisted together to minimize electrical interference. (See STP and UTP).

	High Density 15		High Density 15 is currently the standard connector for PC monitors and video cards.
	BNC		BNC connectors are very secure bayonet-style locking connectors that are used in broadcasting gear for both video and radio signals. It is also common on professional test equipment. In consumer audio/video, BNC connectors are mostly used in high-def set-top receivers and high-end video monitors, often as RGB or component video inputs. This connector is used on older monitors, frame buffers, and accelerators. Many third party monitors also have this connector.
	DB9		This connector is used on older monochrome monitors.
	DB15		This `D-Shell' connector was used for pre-sun4 keyboard connections, such as the Type-3 keyboard. The standard AUI connector is used for network connections.
	DB25		DB25 is a 25-pin connector borrowed from the computer world, where it's been used for both serial and parallel ports; sometimes DB25 is used for controlling audio gear by computer or on THX gear, to connect multiple audio channels with one cable. This connector type is also used in custom installations where numerous cables must be bundled. It’s used for some RS232 and RS423 serial connections. DB25 is also used for the parallel connection on IBM printers.
	DB37		D shaped connector with 37 pins, commonly used in RS449 cable assemblies.
	DB50		A D shaped connector with 50 pins arranged in three rows. This connector is used as the SCSI connector on some Sun workstation models.
	DB68		68-pin SCSI-3 connectors are found on the cables used to connect external peripherals to a differential or wide SCSI interface.
	Header 26		Header 26 connectors have 26 pin insulation displacement connections. These connectors are used with ribbon cables for non-shielded, internal SCSI cabling. When using cables, the female type.
	Header 40		Header 40 pin insulation displacement connections are used with ribbon cables for non-shielded, internal SCSI cabling. When using cables, the female type.

	Mini DIN 4		A small type of DIN connector most often used for keyboard and mouse connections.
	RCAM		RCAM is the most common audio connector; it is used for every sort of analog input and output. These connectors come in color-coded pairs (usually red for right and black or white for left). RCAM connectors are also used for composite-video (coded yellow) and coaxial digital audio cables. "Coaxial" means the signal carrier and its shield are aligned along the same axis (generally a signal wire runs down the middle of a cylindrical shield). RCAM connectors were first used to connect early electronic record players to radios and still sometimes called "phone jacks."
	RJ-11		RJ-11 is the common modular telephone jack. It is used universally on phones, modems, and faxes. These connectors are also used in satellite TV receivers to keep track of things like pay-per-view transactions.
