A true breakthrough in the installation and ownership of protection and control systems. The Multilin HardFiber System saves Utilities up to 50% in total P&C labor costs by replacing thousands of copper wires with IEC 61850 digital communications over a few fiber optic cables. GE Digital Energy makes IEC 61850 Process Bus a reality, delivering significant lifecycle cost savings with the next-generation in protection and control.

HardFiber Brick

• Simple interface providing four bi-directional point-to-point connections with protection and control devices
• Extremely rugged construction — Die-cast Aluminium housing rated IP66, -40°C to 85°C, 30g shock
• Fast, error-proof installation — Copper and fiber cabling with rugged MIL-D-38999 standard connectors

HardFiber Cross Connect Panel

• Break out all of the bi-directional fiber communications channels from Bricks and protection and control devices
• Mapping between Bricks and P&C devices is hard-fibered using simple fiber patch cord connections
• Completely passive infrastructure — no firmware, no settings, no active electronics

HardFiber Outdoor Cable

• Complete bi-directional point-to-point fiber communications and fused power supply for each Brick
• Delivered cut to length and pre-terminated at both ends — no field splicing or terminating required
• Extremely rugged — run in cable trays, pull through conduits, direct bury

Universal Relay IEC 61850 Process Card

• Communications interface between the relay and up to eight Bricks, including synchronization, data alignment and contact input processing
• Transmits commands to connected Bricks to operate primary power system apparatus
• Real-time system health monitoring and data cross-checking — unprecedented level of error detection and security
