Part #:
S1550-HTA

1550 nm Single-Mode Bend Insensitive and/or Radiation Hardened Fiber

This family of three different single-mode fibers is specifically designed for non traditional data and telecom applications that use standard telecom wavelengths. Tactical fiber survives and transmits light even under extreme mechanical duress. The R1310-HTA operates identically to SMF-28™ with improved radiation performance. It is also EMP immune and can withstand very high electrical field strengths. The pure silica core S1550-HTA fiber is also designed to be bend insensitive and withstand extreme pulsed and continuous ionizing radiation. All fibers in this series come with high proof strength, large Weibull modulus, and superior dynamic fatigue parameter to maintain high mechanical reliability (long lifetimes). To meet the challenges of the harsh tactical, avionics/aerospace, missile and UAV working environments, the fibers have high temperature acrylate as the standard coating.

Note: This fiber is U.S. Department of Commerce Export Controlled.
