These fiber-compatible extenders can be used with multimode or single-mode fiber optic cable. Maximum distance over multimode fiber is 3281 feet (1000 m). Maximum distance over single-mode fiber is 6 miles (10 km). Also available in models compatible with CATx cable. Modular housing enables high-density mounting within 19" racks (up to six (6) devices in 1U). Modular housings range in size from 2, 4, 6, or 21 ports for transmitter and receiver cards. Matrix switching chassis are available (DKM FX chassis, see "Related Items").The extenders also work as point-to-point KVM extenders.
The DKM FX extenders consist of at least one transmitter module (ACX1T) and one receiver module (ACX1R). The various extenders can be mounted in a modular housing (ACXMODH). The transmitter is connected directly to the source (computer, CPU, signage publisher); the receiver is connected to the console devices (monitor, keyboard, and mouse). Transmitters and receivers communicate with each other through the matrix switch via CATx or fiber optic interconnect cable.
