SPECIFICATIONS

  • The FOMi-40, Fiber Optic Modem, provides a long range (up to 100 km / 62 miles), and a secure data link between computers, routers, multiplexers and other data communication devices. It operates at 14 selectable synchronous data rates from 56 kbps to 2048 kbps.

  • FOMi-40 converts electrical signals from DTE equipment into optical signals via an infrared light emitting diode or a laser diode. At the opposite end of the fiber, the optical signals are converted back into electrical signals in compliance with the appropriate interface.

  • Two versions of FOMi-40 are available: Master and Slave. The Master standalone version features a front panel LCD. The Slave unit has a blank front panel with a 20-pin connector. For cases where parameters of the slave, master or system alarms have to be monitored and changed on the slave side, a Portable Control Unit (PCU) can be connected to the 20-pin connector.

  • The modem uses an in-band management channel for controlling and monitoring the remote unit. Both data and management are transmitted over the same fiber link, simultaneously, without interference.

  • Menu-driven software, available on the front panel, allows the user to soft select the monitoring and adjustment of local and remote units.

  • The front panel software menus allow the user to monitor and control the following parameters:

    • Data rate (when set to Internal or Receive mode)

    • Clock source

    • Loop activation

    • Internal BER tester activation

    • LED status of local and remote units

    • Local and remote unit settings

    • Real time alert of fault conditions.

  • When set to External mode, FOMi-40 automatically detects the clock rate coming from the digital interface and sets the remote unit to work at the same rate. When the data rate of the external clock is changed, both local and remote units follow the new rate and synchronize accordingly.

  • FOMi-40 utilizes a Phase Locked Loop (PLL) circuit to recover jitter-free data and clock from the optical signal.

  • FOMi-40 is designed to operate with several grades and sizes of fiber optic cable. Different optical interfaces are available:

    • 850 nm for use with multimode fibers

    • 1300 nm for use with single mode fibers

    • 1300 nm laser for use with single mode fibers

    • 1550 nm laser for use with single mode fibers.

  • Immunity is provided against electrical interference such as EMI, RFI, spikes and differential ground loops. Protection is provided against sparking and lightning, and a secure link is maintained in hazardous or hostile environments.

  • Timing is derived from three alternate switch-selectable sources:

    • Internal, from a built-in oscillator

    • External, from the attached DTE

    • Receive, from the received signal.

  • FOMi-40C is a card version for LRS - 12 and FOMi-40CD is a double modem card for the LRS - 24, 19" modem rack with SNMP management, which can accommodate up to 12 or 24 modems. These card versions can be managed in an LRS 12/24 hub from an ASCII terminal or by a RADview. RADview, RAD's SNMP management application running on PC or HPOV UNIX platform.

  • The diagnostic facility of the unit includes different loop tests and an internal BER tester. The available loops are:

    • Local analog loopback

    • Local digital loopback

    • Remote loopback
