with two or more conductors held together by an insulating jacket that can be easily separated simply by pulling apart. In Australia it is known as 'figure-8' cable. The zip-cord term is also used with optical fiber cables consisting of two optical fibers joined in a similar manner. The design of zip-cord makes it easy to keep conductors that carry related electrical or optical signals together and helps avoid tangling of cables. Typical uses include lamp cord
