Corning G.657.A2 Bend-Insensitive Single-mode Armored Fiber Cable | 0.1dB Ultra Low Loss | LSZH | Black


  • Corning G.657.A2 bend-insensitive fiber — dramatically reduced macrobend loss even at tight bend radii, ideal for congested racks, tight indoor conduit turns, and space-constrained installs
  • 3.0mm steel-tube armored construction — crush and rodent resistant, built for outdoor duct runs, building risers, and in-wall/interior renovation routing where cable protection matters
  • 0.1dB ultra low insertion loss — factory-tested single-mode Corning fiber delivers Hi-Fi grade optical signal integrity and clean electrical isolation
  • 100% tested for insertion loss and return loss before shipment

Low-smoke, halogen-free jacket for safer indoor routing

This armored fiber optic cable is built around Corning G.657.A2 single-mode fiber, an ITU-T G.657.A2-compliant fiber engineered for superior bend performance — it maintains signal integrity at bend radii far tighter than standard G.652D fiber, making it the right choice for tight routing paths where conventional single-mode cable would suffer macrobend loss.

The 3.0mm jacket is reinforced with a steel-tube armor layer, giving the cable strong resistance to crushing, rodent damage, and physical stress. This makes it suitable both for outdoor duct and aerial routing and for indoor interior renovation work — running fiber inside walls, under flooring, or through conduit during a remodel.

Every length is manufactured and tested to 0.1dB ultra low insertion loss.
