  • Page 3: Dual -Wavelength

    Converter introduced here provides a pair of one channel single fiber media conversion between 10/100BASE-TX and 100BASE-FX Single Fiber. Dual-Wavelength Single-Fiber These types of Single-Fiber modules combine transmit and receive signals onto one fiber strand using two wavelengths. This design avoids the budget losses incurred by the single-wavelength single-fiber technology, and minimizes any possibility of reflections in the system.
  • Page 4: Installation

    NSTALLATION This chapter gives step-by-step installation instructions for the Converter. Selecting a Site for the Equipment As with any electric device, you should place the equipment where it will not be subjected to extreme temperatures, humidity, or electromagnetic interference. Specifically, the site you select should meet the following requirements: The ambient temperature should be between 32 and 104 degrees Fahrenheit (0 to 40 degrees Celsius).

    port. Refer to the table below for more details. Full Duplex Half Duplex (default) Installing in a Chassis The Converter can be fit into any of the expansion slots on a special designed chassis. First, install the converter onto a carrier supplied with the chassis: Step 1- Unscrew and pull out the media converter board.

Through the optional Media Converter Chassis System via Management Module, you can control the setting of this Smart Media Converter.
  • Page 8: Function

    Link Pass Through Function LLR (Link Loss Return) When a device connected to the converter and the fiber line loss the link, the converter’s fiber will disconnect the link of transmit. The switch 5 is to enable or disable the LLR function of the media converter.

    When using a DMC-920R that the TX(transmit) is 1310µm and the RX(receive) is 1550µm, then the other end need to have a combination of DMC-920T that the TX(transmit) is 1310µm and the RX(receive) is 1550µm. The TX needs to connect to the other end’s RX with the same wavelength.
