There are two answers for this question. The first deals with composite signals and the second deals with cable. So...
Answer one.
Composite signals carry color video as a single signal. The resolution is limited to 480 lines or 576 lines because they are the two standard definition line counts. The signals are below 6MHz and are analog. There is no composite signal that carries HD signals.
Answer two
The cable that carries composite signals is generally fairly poor quality but is sufficient for short links between a DVD and a television for example. Longer runs need a co-ax cable designed to run video signals. The cable is identified as a 75 Ohm cable, that being a characteristic of the cable required for standard video transmission.
Although there are many different grades of co-ax cable, a reasonable quality cable is capable of running any composite signal and will also run digital video in standard and high definition as well. Most video signals use the same type of cable so strictly speaking, there is no such cable as "composite".
