Fiber optic cable wrapped with steel strand
Fiber optic cables are commonly supported by a steel messenger strand, which bears the cable's weight and is secured using stainless steel lashing wire.Steel Messenger StrandA steel messenger strand is a stranded steel cable designed to support aerial fiber optic cables. It typically consists of six wires wrapped around a central wire, often made of carbon steel with a zinc or zinc-aluminum coating to prevent corrosion, even at cut ends . Coating classes (A, B, C) indicate the thickness of the protective layer, with zinc-aluminum coatings providing higher corrosion resistance for harsh environments such as coastal areas . Messenger strands are specified by diameter and tensile strength to ensure they can safely support the cable and withstand environmental loads like wind, ice, and snow .Lashing Fiber to the MessengerLashing wire is used to attach the fiber optic cable to the messenger strand. This wire is usually stainless steel, 0.038" to 0.045" in diameter, annealed for ductility, and rated for 70–90 kpsi minimum strength . The lashing process involves wrapping the wire around the messenger and cable in a helical pattern, securing the cable while allowing for some movement to reduce stress on the fibers . Proper tensioning of both the messenger and the lashed cable is critical to maintain safe sag and prevent overloading the cable's tensile limits .Installation ConsiderationsCable Types: Figure-8 cables integrate the messenger and fiber into a single jacket, simplifying installation, while All-Dielectric Self-Supporting (ADSS) cables do not require a separate messenger .Tensioning: The messenger strand must be tensioned to handle the cable weight plus environmental loads, keeping sag within safe limits .Corrosion Protection: Zinc or zinc-aluminum coatings on the steel strand prevent rust, extending the lifespan of the aerial installation .Permits and Planning: Aerial deployment requires route surveys, pole readiness, and local permits, especially if lashed to existing infrastructure .Bending Radius: Fiber cables must not be bent below their minimum radius to avoid damage or signal loss .SummaryAttaching fiber optic cables to a steel strand involves using a corrosion-protected steel messenger to support the cable and stainless steel lashing wire to secure it. Proper tensioning, sag management, and adherence to installation standards ensure the longevity and reliability of the aerial fiber network . This method is widely used for cost-effective and rapid deployment of fiber in aerial environments.

OverviewEtymologyHistoryTechnologyLashed cableUsesAlternativesIn the media
Optical attached cable (OPAC) is a type of fibre-optic cable that is installed by being attached to a host conductor along overhead power lines. The attachment system varies and can include wrapping, lashing or clipping the fibre-optic cable to the host. Installation is typically performed using a specialised piece of equipment that travels along the host conductor from pole to pole or tower to tower, wrapping, clipping or la
