OS2 – Duplex Single Mode

[huge_it_slider id=”10″]
Duplex OS2
Cleerline SSF™ fiber Duplex cable is composed of two strands of OS2 cable in a zipcord style with an overall 3.0mm Riser, Plenum, or LSZH jacket.

Applications include: inter-building and intra-building voice or data communication backbones requiring 3.0mm jacket diameter. Install in ducts, underground conduits or aerial/lashed.

Cleerline SSF™ Duplex cable is stronger, safer, and faster to terminate than typical fibers. Increased bend insensitivity and tensile strength is achieved via the integral polymeric coating at glass level. Cleerline SSF™ fibers are compatible with all common connector systems on the market for standard 50/125 multimode and 9/125 Single mode fibers.

Features And Benefits:
  • High mechanical strength and superior fatigue & durability
  • Integral coating eliminates stripping, provides glass protection
  • Up to 10,000x the bend longevity of traditional fibers
  • Increased safety factor due to the incredible bend insensitivity
  • Glass fiber remains protected at all times from the elements
  • Simplified termination process designed for ease of use
  • Ultra low Attenuation loss on tight bend radius
  • Exclusive 250um Soft peel jacket identifier
