Fiber optic cables functions to protect the optical fiber from mechanical damage such as bends, breaks, or cuts both during and after installation. It designs incorporate central strength members that have negative temperature coefficients of expansion so that the positive expansion caused by the outer jacket material is neutralized. It is used for data transmission in industrial environments. It is composed of three sections: the core, the cladding, and the sheath. The core & cladding are composed of either glass or plastic. The sheath is a polyurethane jacket that surrounds the cable. The sheath protects the fiber optics from the environment.

Fiber optic cables use glass (or plastic) fibers to transmit data. It consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. It contains large data carrying capacity. Signals can be transmitted further without refreshed or strengthened. Single mode cable is a single stand of glass fiber with a 8.3 to 10 microns that has one mode of transmission. Multimode cable is made of glass fibers, with common diameters in the 50 to 100 microns range for the light carry component.

Fiber optic contact closures provide point-to-point contact closure information over a single fiber optic cable. These are used to convert up to ten contact closure inputs into fiber optic signals for transmission over a single fiber optic link.

Fiber optic converters are designed to take copper networks, convert them to fiber optic signals, and convert them back again. It has an integrated back plane. It represents an extremely flexible and scalable solution to the problems often encountered when using copper to interconnect communication nodes. Both multi-mode and single-mode fiber optic links are supported. Problems such as ground loops, isolation and lightning strikes are eliminated with the fiber optic converters. Fiber optic communications links can also be extended over much greater distances and take on physical topologies not available with copper networks.
