Fiber optic cable (English: optic fiber cable) is a cable based on optical fibers, designed for transmitting optical signals in communication lines.

The fiber optic cable of the J-V(ZN)H design consists of one or two optical fibers (dual version) in a dense buffer coating (covered with a 900 micron primary buffer), power elements in the form of Kevlar threads (aramid fibers) and a sheath for indoor use. The sheath of such a cable usually has a diameter of 2-3 mm. A double differs only in that it consists of two single ones connected to each other (possibly called duplex).
This type of fiber optic cable is used mainly in the production of optical patch cords or connecting workplaces, vertical and horizontal SCS subsystems.
The cable can be supplied with different types of optical fibers, OM1 OM3, two types of multimode fibers with 62.5 µm and 50 µm optical fibers, for visual distinction, the outer sheath of the cable with OM1 fiber is orange, with OM3 fiber turquoise. The sheath material is non-smoking and non-flammable LSZH/FRNC.
Before the J-V(ZN)H marking was used, the J-VH marking was used to designate this type of cable.
