FILM — A thin plastic sheet. Make sure staples are shorter than flange thickness so that they cannot extend through the flange and damage the cable. Normally the failure of an insulation because of excessive voltage. Acble is the most common and is used for improved corrosion resistance and solderability. The FDDI connector also has a keying system to prevent connections of incompatible network nodes.
Though there are a few variations in tip material, this connector is most often an epoxy oven or 24 hour cure type installation. The test measures relative flame propagation of a single wire or cable. Routine periodic DC maintenance testing of cable for the evaluation of the insulation strength is not a common practice.
The interlocking construction protects the cable from damage during and after installation. Velocity of propagation is the speed at which electromagnetic energy travels along the cable.
For information on the various types and their applications, see Chapter 5 on Armor. The higher the operating temperature of the insulation, the handbooo the currentcarrying capacity of a given conductor size.
Aluminum 1 Outside diameter—1. A For bare conductors where greater flexibility than is afforded by Class AA is required. Bolt illustrations not drawn to scale.
For flat twin cables, the minor diameter is used to determine the bending radius. For this reason each phase hanbook of such a cable has additional insulation.
Additionally, cables jacketed with polyvinyl chloride presented the dangers of toxic fumes and dense, impenetrable smoke when undergoing combustion. Core Diameter The fiber core is the central region of an optical fiber whose refractive index is higher than that of the fiber cladding.
Feeding Cable onto Reel Care must be used when feeding cable onto the take-up reel. Lengths are limited due to amount of material in the ram, thickness of the insulation, and preform size.

Dry nitrogen is available from welding gas suppliers. One of the many services often found on broadband networks.
DC — Direct current. The connector can be installed directly onto a tight buffered fiber. Tests are normally conducted by the Quality Control Department, and shows that the product being shipped meets the required test specifications. Type 2 1, Apparatus and Motor Lead Wire: Refers to the use of a coaxial or fiber cable to transmit television or other signals to subscribers from a single head-end location.
After that time, DC testing is not recommended. Fibers are either multimode or single mode. This need for impedance matching is especially critical at higher frequencies, where the consequences of mismatches are more severe. Single- and multiple-conductor cable in coilable nonmetallic duct Outside diameter of duct, inches—0.
Installation Normal cable loads sustained during installation or environmental movements first stress the strength members without transferring cagle stress to the optical fibers.
It is an opaque, white material although some forms are translucent in thin sections. EMI — Electromagnetic Interference.
Velocity of propagation is expressed as a percentage of the speed of light. There are four receptable keys: A device that converts a digital input signal to an analog output signal carrying equivalent information.
All informatioon and cable has a minimum safe bending radius.
A voltage higher than normal operating voltage is applied across the insulation. CPE — Dow Chemical trademark for chlorinated polyethylene.

In locations where corrosive conditions may be encountered, a jacket over the lead is recommended. Typical values are shown below.
Its low temperature impact resistance is excellent. It is the standard coaxial connector for many coaxial cable based local area networks, including Ethernet and other IEEE networks using medium size coaxial cable.
