HardFiber Brick - Switchyard Hardened Interface
The HardFiber Brick is a simple interface providing four bi-directions point-to-point connections to protection and control devices. Its extremely rugged die-cast aluminum housing is rated IP66, from -40 to 85C, and 30g shock. The HardFiber Brick is designed for fast, error-proof installation using standard MIL-D-38999 for copper and fiber cabling.

HardFiber Cross Connect Panel
The HardFiber Cross Connect Panel breaks out all of the bi-directional fiber communications channels from the Brick and the protection and control devices. Mapping between these devices is hard-fibered through simple fiber patch cord connections. Using a completely passive infrastructure, the Cross Connect Panel has no firmware, no settings, and no active electronics.

HardFiber Cables
The HardFiber Cables serve as dual purpose, as both a bi-directional point-to-point communications medium and as the fused power supply for each Brick. Delivered cut to length and pre-terminated at both ends, these rugged cables require no splicing and can be run in cable trays, pulled through conduits, and directly buried.
