Extra Protection for Use in Harsh Environments. Now Available in Laser-Optimized Grade for Enhanced Performance at 1 Gigabit Ethernet.

Product Description

OFS offers standard and 1 Gb/s multimode fibers with a 500 µm diameter dual layered acrylate protective coating. This coating, three times the thickness of conventional 245 µm coated fiber, provides maximum protection of the fibers for special use applications in rugged environments.


  • Extra thick coating for exceptional (microbend and mechanical) protection
  • Superior geometric tolerances and very low attenuation
  • Enables minimal connection loss and low cabled attenuation
  • Quality ensured through Differential Mode Delay (DMD) testing
  • Allows Gigabit Ethernet operation up to 600 meters at 850 nm
