The industry standard in reliability, from mining cables to NEMA 4x Enclosures.

OCC’s mining solutions deliver reliable mining connectivity. Our fiber optic cables are designed to meet high-survivability standards and repeatedly endure the severe mechanical and environmental stress found in surface and subsurface mining. Our MSHA-rated cables are optimized to withstand the rigors of difficult cable pulls, high-tensile loading, and are easy to install. Where other manufacturers’ cables fail, OCC’s MSHA cables are particularly well-suited to survive the harsh environment associated with mining applications. OCC’s unique cabling and connectivity configurations provide long-term reliability, security, and even reusability in mines.

What makes OCC Mining products superior?

  • OCC’s special Core-Locked jacket is extruded under high pressure directly over the cable’s core, resulting in the internal surface of the cable jacket having helical cusped ridges that interlock with the subcables. This helps keep the cable cross-section circular for better crush and impact protection and provides superior tear resistance during installation.
  • Helical stranding is a time-tested cable construction design proven to provide flexibility, survival in difficult pulls, and excellent mechanical protection for the optical fibers. This design ensures that no one particular element of the cable receives more stress than the other elements – thus equalizing the stress load associated with particularly tough installations.
  • Our water-blocked fiber optic cables provide the best water protection system available by combining the inherent water tolerant features of tight-buffered and Core-Locked™ tight-bound cable with super absorbent polymer aramid yarn. This design provides superb water-blocking performance while retaining the termination cost advantages of totally gel-free and powder-free, tight-buffered cable.
  • OCC’s Ultra-Fox™ and Ultra-Fox™ Plus cables feature a unique fiber construction consisting of a primary coating of a UV-cured acrylate material and a tight-fitting secondary coating that provides an extraordinary level of protection.

All of these factors make OCC's cables a practical and reliable means of high-capacity data transmission in challenging environments without the delicacy normally associated with traditional fiber optic cables.

To complement our MSHA cables, OCC manufactures a variety of rugged, multi-channel fiber optic and electro-optic connectors. One such family of products is our compact Mini-Hermaphroditic Connector (MHC® II). These connectors are available in both multimode and single-mode versions as well as electro-optic design, and, along with many of OCC’s harsh environment connectors, are hermaphroditic. This allows cable assemblies to be daisy chained together, making it simple to extend the underground fiber optic backbone system without the need for gender-changing adapters. Power or control signals for active equipment may be supplied using hybrid connector options that add electrical and optical signals within the same connector body. These connectors withstand extreme environmental demands and they are specifically designed for reliable data transmission signals.

To complement the OCC mining system, OCC offers the Modular Advanced Reel System, or MARS, a lightweight, durable system constructed of a high-impact glass-reinforced polymer that is easily transported and ideal for applications where cable needs to be deployed and reeled in quickly and stored efficiently. Available with a multitude of storage and deployment accessories, the MARS system allows mining operations to easily replace fiber optic segments with limited down time.


Utilizing the capacity and capability of fiber optic cabling systems, mines can operate more cost-effectively and with greater efficiency. OCC’s mining cables provide reliability, security, and reusability in mines. Our expert staff can help design a deployment system that uses our high-performance cables and reliable mining connectivity. Our mining solutions increase productivity in areas such as:

  • Environmental Monitoring
  • Security
  • Intrinsically Safe Areas
  • Automation
  • Production Rates and Yields
  • Equipment Control and Monitoring
  • Voice/Data/Video Communications
