SteelFlex Armored (Formerly Heavy Armored) Fiber Cables

OptoSpan SteelFlex Armored cables feature an exclusive OptoLock mechanism comprised of a steel metal tube that is locked into position by overlapping links.  This composition results in an unmatched rugged, but light weight cable that provides maximum flexibility.  Bringing additional protection over SteelPatch, SteelFlex Armored fiber cables encase the internal fibers with no gaps in between, ensuring a complete protective layer for harsh outdoor environments.  Other OptoSpan Armored Fiber Optic Cables include SteelPatch Armored Fiber Cables, 6-24 Fiber Armored Breakout Cables, Plenum Armored Fiber Cables, Armored MTP Cables, Armored MPO Cables, and Armored MTP Elite Cables.
