Summarize of ETH Fiber Modem


Ethernet fiber modem is to modulate Ethernet signal to single or multi-mode fiber. The fiber for transmit data can be used to monitor and control local and remote devices, and no collision will occur, user can chose the type of commonly fiber wavelength and interface. It also can used with E1 fiber optical modem and transmit by ATM or DDN.


Application of ETH Fiber Modem


The ETH Fiber Modems can be used with E1 Fiber Modems and switches to connect two or more host.

ETH Fiber Modem Application

Install the ETH Fiber Modem to the MDI/MDI-X switch


Do the following to install the Ethernet fiber modem to the MDI/MDI-X switch.

  1. The MDI/MDI-X switch enables you to connect the ETH Fiber Modem to different types of network devices by using a standard network patch cable. To connect the ETH Fiber Modem to a terminal, transceiver or network interface card (NIC), set the switch to the MDI-X (left hand) position. Otherwise, to connect to a hub or switch, set the switch to the MDI (right hand) position.

  2. The modem comes equipped with a shielded RJ45 Jack for Ethernet connections. Connect the Ethernet RJ45 Jack to the appropriate 802.3 compliant network equipment via a standard network patch cable.

  3. Connect the dual fiber ST/SC/FC connectors on the ETH Fiber Modem directly to the 802.3 compliant multi-mode fiber cable equipped with male ST/SC/FC connectors or via 802.3 compliant multi-mode fiber patch cord and corresponding ST/SC/FC fiber wall jacks.

  4. Connect the DC power output side of the power supply adapter to the power jack on the modem.

  5. Connect the AC power side/cord of the power supply adapter to the appropriate AC power source.

Then, the Ethernet Fiber Modem will power up and LED indicators will illuminate once connected to the power source.
