Ethernet Cable Assemblies

Ethernet cable assemblies are designed to support Ethernet, a standard protocol for the connection of computers in a local area network (LAN). There are many different types of Ethernet cables. Choices include 10Base-T, 10Base-2, 10Base-FL, 100Base-TX, 100Base-FX, 1000Base-T, 1000Base-LX, and 1000Base-SX. Other types of Ethernet cable assemblies are also available. 10Base-T Ethernet cable assemblies use twisted-pairs with modular connectors. 10Base-2 cables use thin, RG58 coaxial cable and Bayonet Neil Concelman (BNC) connectors. These Ethernet cable assemblies are also known as BNC Net, Thin Ethernet, or ThinNet. 10Base-FL implements the IEEE 802.3 standard over fiber optic cable at 1- Mbps baseband. 100Base-TX and 100Base-FX also adhere to this popular Fast Ethernet standard from the Institute of Electrical and Electronics Engineers (IEEE). 1000Base-T complies with IEEE 802.3ab, a standard which defines 1 Gb/s data transfers over distances up to 100 m. 1000Base-LX and 1000Base-SX comply with IEEE 802.3z, a specification for Gigabit Ethernet over fiber optic cable.

Cable construction is an important parameter to consider when selecting Ethernet cable assemblies. Choices for cable type include: Cat 3, Cat 5, Cat 6, coaxial, fiber optic, RG6/11, triaxial, type 1 and twisted pair. Cat 3 cables meet the EIA-568 commercial building telecommunications standard and are designed for transmissions up to 16 MHz. Cat 5 cables are unshielded twisted pair (UTP) cabling that offers speeds up to 100 MHz and data transfer rates up to 100 Mbps. Standards for Cat 6 cable are still under review. Coaxial cables consist of two cylindrical conductors with a common axis. Fiber optic cables provide near-infinite bandwidth and perfect immunity to noise. RG6/11 cables are relatively inexpensive and used in cable television applications. Triaxial cables have one conductor in the center, a second circular conductor shield concentric with the first, and a third circular conductor shield insulated from and concentric with the first and second. Type 1 cables are used in Token Ring networks and other LANs. 

Ethernet cable assemblies differ in terms of cable length, gender, connector type, applications, and features. Choices for gender include: male-male, male-female, and female-female. Choices for connector type include: Centronics 36 and Centronics 50; high density 15; Bayonet Neil Concelman (BNC); DB9, DB15, DB25, DB37, DB50, and DB68; Header 26, Header 40, Header 26, Header 40, and Header 50; internal 50-pin SCSI and internal 68-pin SCSI; micro-Centronics 36, micro-Centronics 50, micro-Centronics 60, and micro-Centronics 68; Mini DIN 4; RJ-11, RJ-12, and RJ-45; Telco 50, RCAM; and USBA and USBB. Some Ethernet cable assemblies are used in audio, camera, computer, military, or medical applications. Others are designed for networking, telecommunications, or video. In terms of features, suppliers of Ethernet cable assemblies may provide products that are shielded, designed for extreme environments, constructed for cleanroom use, or incorporate a hydra assembly.
