Multimode Optical Fiber (MMF)

Mercury’s multimode fibers are graded index multi mode optical fibers which have core diameter of 50㎛(multi-mode fiber) and 62.5㎛(high NA multi-mode fiber).
These fibers have the highest bandwidth and lowest attenuation, which is optimized for 850nm and 1300nm operation wavelength region. For excellent optical and mechanical performances all materials are specifically engineered to meet all industry specifications.

  • Optimized at 850nm and/or 1300nm operation windows.
  • Uniform geometrical characteristics for excellent splicing.
  • Dual coated construction for minimum bending-induced loss.
  • Compatible with full line of premises distribution products.
  • Local area and central office networks.
  • High performance computer & Data networks.
  • Voices / Video Services
  • Distribution systems and Trunk systems.
  • 1~100 Gigabit/s Ethernet
