The TotalWire TWF2-1000 advanced optical glass fibers are much stronger, safer, and faster terminating than typical fibers. This duplex style cable provides ultimate durability and bend with ease of termination. TWF2-1000 fibers are always protected at the glass level as a result of their integral polymeric coating, increasing both bend and tensile strength.


Key Features:

  •          High mechanical strength and superior fatigue/durability
  •          Integral coating eliminates stripping and provides glass protection
  •          10,000x the bend of standard fiber
  •          Glass fiber remains protected at all times
  •          Ultra-low Attenuation loss on tight bend radius
  •          Simplified termination process
  •          Exclusive 250um Soft Peel jacket identifier
