Loop Telecom Fiber Optical Multiplexer 8E1 Ethernet chassis O9210S / Loop-O9210-S-4E120-4E75-NHB4F-AoD

SKU: 2774 Category:



Loop-O9210S is a point-to-point optical transmission device developed from VLSI that provides not only a choice of fixed 4E1 or 4E1 plus 100M Ethernet bridge, but also the expansion of another 4 E1 links for multiplex transmission over an optical fiber. It provides longer reach without repeaters and superior performance compared to copper media.

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