A protective member for a wire harness, having a branching point between a trunk harness and a branch harness, includes a protective sheet portion to be wound around an outer circumference of at least the trunk harness near the branching point; a pair of band-shaped fixing strip portions extending from the protective sheet portion and to be wound around on the trunk harness at a pair of spots. The branching point is between the pair of the spots. The protective member is formed from a resin. The fixing strip portions are smaller in thickness than the protective sheet portion.

Cables that include a conductor and an optical fiber. In some embodiments, the cable can include an optical fiber loosely disposed within an enclosure. A conductor layer can be disposed about the enclosure. An insulation layer can be disposed about the at least one conductor layer. An inner layer of armor strength members can be helically disposed about the insulation layer. An outer layer of armor strength members can be helically disposed about the inner layer of armor strength members. The armor strength members in the outer layer of armor strength members can be at an opposite helix compared to the armor strength members in the inner layer of armor strength members. An outer jacket can be disposed about the outer layer. In other embodiments, the cable can include an optical fiber in a coupled electro-optical package, where the conductor layer can be disposed about the electro-optical package.

A transmission line includes a conductor for signal transmission. The transmission line also includes a plurality of isolating individuals arranged to cover the conductor as an isolating layer of the transmission line. The isolating layer has at least one air gap.
