General information:
FMO-480-BNC can multiplex to 16 E1 signals for transmission over an optical fiber, resulting in reaching a longer distance without repeaters and superior performance compared to copper media. FMO-480 is the 16e1 point-to-point optical transport equipment that uses the FPGA chips and it is easy to upgrade. It is single board structure and the largest transmission capacity is 16e1. The outer design use the standard 19 inches rack, so the volume is little, weight is light and operation is convenient and credit. 16e1 fiber Mulitplexor uses the PDH fiber transmission technologies. The 2M (E1) interfaces can connect with the exchanger, light loop device and multi-diplexer directly to form the mirco-midi or the special network. Complete alarm function for FMO-480, it is stable and easy to maintenance, install and small in size. It has one digital service telephone.
Can be used as a high-speed baseband modem for point to point that connects two DTE over a lease Line. From Router to CSU/DSU to FMO-480 to Fiber optical to FMO-480 to CSU/DSU to DTE.
Product characteristics:
Offer 16 X 2Mb/s digital interfaces.
Up to 16 E1 links on one fiber.
Management through Console port.
The supervisory control interface implements centralized monitoring and export the monitor and control information of this port and opposite port.
One link to service telephone for duty contract.
90-260VAC & -48VDC power options and the positive and negative of DC-48V can be optional because there is the self-test circuit for the polarity inside th1e device.
