394-O9210S PDH Fiber Optical Mux (Loop Tech)
Or call us on
Loop Tech's Loop-O9210S is a point-to-point optical transmission device developed from VLSI that provides not only the choice of fixed 4E1 or 4E1 plus one 100M Ethernet bridge, but also the expansion of another 4 E1 links to multiplex transmission over an optical fiber. The Loop-O9210S provides longer reach without repeaters and superior performance compared to copper media.

The Loop-O9210S has a profound alarm monitoring system, and also local and remote loopbacks controlled by the console or DIP switch. With its high integration, low power consumption, stability, and desktop-mount design, installation and operation become easy and convenient.
