About the Miniature Media Converter 10/100 Switching and Miniature Media Converter w/SFP

The Miniature Media Converter 10/100 Switching and Miniature Media Converter w/SFP provide a single conversion between 10/100 Base-T twisted pair and 100 Base-SX/FX fiber. This device Auto Negotiates speed and duplex on the copper port and the fiber is fixed at 100Mbps. There is a fixed fiber and an SFP version available; both support jumbo frames up to 1916 MTU.

The Miniature Media Converter 10/100 Switching is a fixed fiber transceiver model, includes one 10/100Mbps RJ-45 connector and one 100Mbps SC fiber connector which can support Single Mode fiber or Multi Mode fiber in Dual Strand or Single Strand fiber.

The Miniature Media Converter w/SFP is an SFP port-based model, includes one 10/100/1000Mbps RJ-45 connector and one SFP port, which was designed to support MSA-compliant 100Mbps SFPs. The model will detect the SFP and run at the speed for which the SFP was designed.

Install the Miniature Media Converter 10/100 Switching and Miniature Media Converter w/SFP

The Miniature Media Converters install virtually anywhere as a standalone device in locations with extremely limited space. Installation options include: Velcro® strips DIN rail mounting with DIN Rail clips Powertrain/18 for high density applications

DIN Rail Mounting

The Miniature Media Converters can be mounted with two DIN Rail clips. Depending on the installation, the Miniature Media Converters can be mounted parallel or perpendicular to the DIN rail. Use the supplied screws to attach the DIN clips to the Miniature Media Converter, and then snap the converter to the DIN rail.

To remove the converter from the DIN rail, use a flat-head screwdriver in the slot to gently pry the converter from the rail.


The DIN clips are designed for use on a DIN-35 rail (part number LXC-DR

Cascading DC Power

When installing multiple Miniature Media Converters on a DIN rail, the end user can connect to one DC input source, and then cascade from one DC block to the next, until reaching the maximum current available.

Powering the Miniature Media Converter 10/100 Switching and Miniature Media Converter w/SFP

The Miniature Media Converter 10/100 Switching and Miniature Media Converter w/SFP include multiple powering options:

  • A country-specific, high-reliability AC power adapter (included)
  • IE Power Tray 18-Slot AC for Rack Mounting
  • USB power cable


LED Operation

Each Miniature Media Converter includes two LEDs, located on the RJ-45 connector. LED functions are as follows:

FX LNK/ACT Glows green when a link is established on the fiber port; blinks green when activity is detected on the fiber port.
X LNK/ACT G Glows green when a link is established on the copper port; blinks green when activity is detected on the copper port.

The Miniature Media Converter with LFPT includes a DIP Switch, located on the back of the unit. DIP Switch functions are as follows:

Switch Up LFPT ON
Switch Down LFPT OFF

Link Fault Pass-Through (LFPT) is a troubleshooting feature that combines TX and FX Link Loss from both the local and remote Mini Mc, TX-FX/SFP modules. LFPT is enabled by turning on the DSW on both modules. This feature allows either end of the conversion to detect a link fault occurring at the other end of the media conversion chain.

Regardless if there is a break in segment 1, 2 or 3, the link will drop on the switches at both ends. The link fault is passed through the media conversion and is observed at each end. It acts just like it would if the devices were directly connected.

Fiber Optic Cleaning Guidelines

Fiber Optic transmitters and receivers are extremely susceptible to contamination by particles of dirt or dust, which can obstruct the optic path and cause performance degradation. Good system performance requires clean optics and connector ferrules.

  1. Use fiber patch cords (or connectors, if you terminate your own fiber) only from a reputable supplier; low-quality components can cause many hard-to-diagnose problems in an installation.
  2. Dust caps are installed at Black Box to ensure factory-clean optical devices. These protective caps should not be removed until the moment of connecting the fiber cable to the device. If you need to disconnect the fiber device, reinstall the protective dust caps.
  3. Store spare caps in a dust-free environment such as a sealed plastic bag or box so that when reinstalled they do not introduce any contamination to the optics.
  4. If you suspect that the optics have been contaminated, alternate between blasting with clean, dry, compressed air and flushing with methanol to remove particles of dirt.

Electrostatic Discharge Precautions

Electrostatic discharge (ESD) can cause damage to any product, add-in modules or stand alone units, containing electronic components. Always observe the following precautions when installing or handling these kinds of products.

  1. Do not remove unit from its protective packaging until ready to install.
  2. Wear an ESD wrist grounding strap before handling any module or component. If the wrist strap is not available, maintain grounded contact with the system unit throughout any procedure requiring ESD protection.
  3. Hold the units by the edges; do not touch the electronic components or gold connectors.
  4. After removal, always place the boards on a grounded, static-free surface, ESD pad or in a proper ESD bag. Do not slide the modules or stand alone units over any surface.
WARNING! Integrated circuits and fiber optic components are extremely susceptible to electrostatic discharge damage. Do not handle these components directly unless you are a qualified service technician and use tools and techniques that conform to accepted industry practices.
