| | Coaxial Cable Introduction (導覽) A cylindrical transmission line comprised of a conductor centered inside a metallic tube or shield, separated by a dielectric (insulation) material and usually covered by an insulating jacket. These cables, originally developed for military use as Radio Guide (RG) cables have wide application in the transmission of video, voice, high-speed digital and high-frequency analog signals. Although some applications are still for military equipment and made to a MIL-Spec standard (M17) most current applications are for commercial use. For identification purposes many coaxial cables still use the "RG" designation followed by a number, this number may refer to a conductor size or the characteristic impedance. Some products carry an NEC rating, some are made to military specifications and some are designed for specific commercial applications and may not carry a specific rating.
SPECIFICATIONS Presented within this catalog section are coaxial cables grouped in eight major application categories widely used today.
MAJOR COAXIAL CABLE TYPES: CCTV / CLOSED CIRCUIT TELEVISION: Widely used for video transmission in security systems BROADBAND / CATV / MATV: Used for either a trunk or drop cable for most CATV (cable TV) systems BROADCAST / VIDEO: Used in all broadcast video applications COMPUTER: Traditional types adapted for signal transmission in OEM and other equipment and systems WIRELESS: Specialty coax used for wireless transmission tower signals (microwave, Cellwave) CENTRAL OFFICE: Coaxial cables usually bundled and used to interconnect DS 3/4 transmission equipment with digital cross connects in the telecommunications sector INDUSTRIAL AUTOMATION: Coaxial cable designed for use on the factory floor including industrial Ethernet and twinax, (sometimes known as non-coax cable) MIL-SPEC COAX: The original coaxial cable designed and updated for modern military equipment; specifications still active for new design equipment may require stringent test requirements and can only be procured from QPL (qualified products list) manufacturers and made to MIL-DTL-17 specification (formerly MIL-C-17), many of the products available in the groups above are commercial versions of these cables. |
