SDH / MSTP multiplexer

Product Introduction:

YKMSTP155 is an upgrade SDH / MSTP multiplexer. SDH / MSTP (Multiple services transmission platform) multiplexer use the new technology integrated components, single board structure. The price is approach to the PDH. It transmit the data/signal via optical fiber which can reduce the material of 2M cable and DDF (digital distribution frame) and reduce the occupying room. It’s 19 inch rack which can insert different interface cards. 1.5U height. Dual power supply backup. Supply AC/DC.
