The FirePRO LDR (long distance repeater), designed and manufactured by Point Grey Research, is the world’s first repeater to use a GigE physical layer to transport FireWire data using GigE signalling, allowing IEEE 1394b 800 Mb/s data to be transmitted in real-time over 100 meters of standard Category 5e cable. This enables users to construct a dependable, high-speed FireWire-based network of multiple cameras that is physically separated by up to 100 meters from the host system. Like other FirePRO hubs and repeaters, the LDR requires no special software or drivers, is fully compatible with 1394b, and is backward compatible with 1394a.
