UFM-680

Fiber Optical Multiplexer

UFM-680 STM-1 optical multiplexer equipment provides a flexible and cost effective solution to transport T1/E1, Nx64kbps and Ethernet Services over optical fiber. With modular system design, UFM-680 can accommodate different plugin cards for E1, T1 and V.35 Nx64kbps to fit user's current and future service requirement. UFM-680 embeds four Ethernet channels on board to share up to 100Mbps bandwidth for data transportation.

The total capacity of four 10/100 Mbps electrical Ethernet ports and up to 16 T1/E1 interfaces optimize the bandwidth utilization over the optical fiber. The optical link has 1+1 redundancy mechanism with APS (Auto Protection Switch) function to increase system reliability.
