Fiber tapping is a network tap method that extracts signal from an optical fiber without breaking the connection. Some systems can detect sudden attenuation on a fiber link and will automatically raise an alarm. One countermeasure of fiber tapping is, to make the intercepted data unintelligible to the thief.

These germanium doped Single-Mode (SM) fibers offer excellent performance in applications where the fiber will be subjected to tight bends. Fibercore's range of SM1250B3 products come in either 125μm or 80μm cladding diameter. Optical Cable Corporation's Indoor/Outdoor tight-buffered fiber optic cables meet the functional requirements of the following standards: UL-listed type OFNR in accordance with NEC sections 770-179 (B) and 770-154 (B) for use in vertical runs in building riser shafts or from floor to floor. Corning's specialty fiber is optimized for diverse applications and plays an integral role in many high-performance telecommunication devices including optical amplifiers, transmission lasers, and external modulators; and is widely deployed in fiber-optic gyroscopes and navigation systems. Light-weight aluminum interlock armor is standard and eliminates the need for inner duct or conduit and the cost associated with the installation of either. In 2007, a new type of "bend-insensitive" singlemode fiber was introduced, followed by multimode fiber in.
