Technical Architecture & Functionality
The Unibrain Glass Optical Fiber (GOF) Repeater 800 Kit (SKU: 2553) is a complete FireWire 800 (IEEE 1394b) fiber optic extension kit that includes two repeater units and two +12V power supplies, designed to extend S800 (800 Mbps) 1394b data transmission up to 550 meters (1,804 ft.) over multimode glass optical fiber (GOF). (Note: Single standalone units are available under SKU 2552).
Capable of extending FireWire connections far beyond copper limits, the GOF Repeater 800 enables reliable long-distance connectivity for broadcast systems, industrial machine vision, scientific instrumentation, and legacy professional AV environments where FireWire remains a critical interface.
The repeater is built around the Texas Instruments TSB81BA3D, the latest revision of the 1394b PHY, ensuring stable performance, full backward compatibility, and reliable operation across mixed 1394a and 1394b systems. Each unit includes two bilingual copper FireWire ports and one LC optical fiber port, allowing seamless transitions between copper and fiber segments.
Housed in a galvanized steel enclosure with polyester powder coating, the GOF Repeater 800 provides excellent durability, EMI resistance, and thermal performance in demanding environments. It supports full-duplex operation, automatic speed negotiation, and operates transparently with Windows, macOS, and Linux systems.
