L-com carries 70 different spools of telecom/modular bulk cables, everything from Flat Modular (also called Silver Satin or non-twisted modular), to Category 3-, 5e-, and 6-rated unshielded twisted pair (UTP) and shielded twisted pair (STP), to T1/E1 individually shielded twisted pairs. So how do you know what you need?
Jacket Types The jacket is the outside material of the cable, which covers and protects the individual conductors within. While the jackets can be one of several colors, the actual material composition may be important to your application, particularly the flammability rating of the jacket (video). The four jacket types available are:
Conductor Sizes Conductors are usually sized according to the American Wire Gauge standard (AWG). The standard runs backwards, so a 22 AWG conductor is much larger than a 28 AWG conductor. In general, the gauges work well with the following conductor sizes:
Conductor sizes are important because not all modular plugs are made the same. The ability to terminate a conductor into a plug or jack is limited and you should always make sure that the cable and plug you intend to use are compatible with one another.
