TAT-12/13 is a ring cable system consisting of the 12th and 13th consortia transatlantic telephone cables, in operation from 1996, initially carrying 2 × 5 Gbit/s.. This was the first TAT cable to use a ring structure, involving two stretches of cable across the ocean floor, which explains why two numbers (12 and 13) were used.
Plenum cable / ˈ p l ɛ n əm / is electrical cable that is laid in the plenum spaces of buildings. In the United States , plastics used in the construction of plenum cable are regulated under the National Fire Protection Association standard NFPA 90A: Standard for the Installation of Air Conditioning and Ventilating Systems.
ANSI/TIA-568.3-D addresses components of fiber optic cable systems, and ANSI/TIA-568-C.4, addressed coaxial cabling components. [ 6 ] The intent of these standards is to provide recommended practices for the design and installation of cabling systems that will support a wide variety of existing and future services.
DIN Standard DIN 47100 regulated the color-coding for the identification of cores in telecommunication cables. The standard was withdrawn without a replacement in November 1998, but remains in widespread use by cable manufacturers. The isolations of the several wires in a cable are either solidly colored in one color, or striped lengthwise in ...
Single-core 25-pair/50 conductor cable. The 25-pair color code, originally known as even-count color code, [1] is a color code used to identify individual conductors in twisted-pair wiring for telecommunications.
Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities, equipment rooms and telecommunications closets. Backbone cabling consists of the transmission media, main and intermediate cross-connects and terminations at these locations. This system is mostly used in data centers.
Optical Carrier classifications are based on the abbreviation OC followed by a number specifying a multiple of 51.84 Mbit/s: n × 51.84 Mbit/s => OC-n. For example, an OC-3 transmission medium has 3 times the transmission capacity of OC-1.
The 20-pair colour code is a colour code used in Australia to identify individual conductors in a kind of electrical telecommunication wiring for indoor use, known as twisted pair cables. The colours are applied to the insulation that covers each conductor. The first colour is chosen from one group of five colours.
