™ Mini-Mux 155 Drop 3 STS-1s, T3s, or AU3s from an OC-3/STM-1 in a one mounting space shelf. ™ Charles Industries’ Mini-Mux 155 Optical multiplexers, the Mini-Mux 155’s very low Multiplexer offers advanced OC-3/STM-1 power consumption and small footprint make it multiplexing features in the industry’s most ideal for use in any location. Full redundancy compact architecture. Programming options for both the optics and drop ports provide high allow you to drop 3 STS-1, T3, or AU3 signals reliability and simple maintenance. Multiplexing from either OC-3 or STM-1, thus providing SONET or SDH bandwidth to your network is tremendous flexibility in a 19” chassis only now both easy to install and maintain. 1RU tall.
