Fiber Optic DMX Transmission System

The DMXT-7001 and DMXP-7001 are specifically designed to transmit, receive and repeat ANSI E1.11-2008 (DMX-512-A) signals at data rates from DC to 1Mb/s on a single optical fiber. The units may be used for point-to-point or in drop and repeat applications over distances of up to 20 miles.

The system operates with standard multimode or single-mode optical fiber and installation only requires the connection of the various signal and fiber optic cables. There are no user adjustments. Indicators are also provided to continuously indicate the presence of repetitive signals as well as the presence of operating power making system troubleshooting simple
