B-Series Breakout - MSHA-Rated Mining Cables


  • Can be installed in locations that require compliance with MSHA's Part 7, Subpart K of Title 30 of the Code of Federal Regulations (CFR) signal cables
  • Suitable for permanent installations
  • Ideal for applications that require individual connectors added to subcables


  • Most rugged cable design with individual subcables for routing and direct connector termination
  • Helically stranded cable core for flexibility, survival in difficult pulls, and mechanical protection for the optical fibers
  • High performance tight-buffered coating on each optical fiber for environmental and mechanical protection
  • Fibers may be directly terminated using connectors, with no further protection required
  • UV resistant, water and fungus resistant
  • Core-LockedTM outer jacket surrounds the subcables for exceptional crush resistance, survivability, and use in long, vertical installations
  • Designed for direct lashing, "J" hook applications, and vertical installations
  • Cable is ideal for direct pulling with wire mesh grips
  • Individual fibers and strength members protected in a subcable configuration
  • Ideal configuration for multiple termination point locations where subcables provide excellent strength and mechanical protection for connector termination
  • Flame retardant - MSHA approved to Part 7, Subpart K of Title 30 Code of Federal Regulations (CFR)
