At its core, media converters are simple devices used to connect two devices or LANs that are not entirely relatable, due to different speeds, operation types, modes or media types (twisted pair, fibre, coax). Most common usage is to insert fibre segments into copper networks. This gives you the ability to extend your Ethernet network beyond the 100-meter limit imposed by copper cable. Media converters can be used anywhere in the network to integrate newer technology with existing equipment to support new applications, technologies and future growth. Instead of costly, across-the-board upgrades, media converters can extend the productive life of the existing cabling as well as the active equipment.

Media Converters Benefits

  • Extend LAN Distances by Using Fibre

    Copper-based Ethernet connections are limited to a data transmission distance of only 100 meters when using UTP cable. By using an Ethernet to fibre conversion, fibre optic cabling can now be used to extend this link over a greater distance of up to 80 km.

  • Maintain Investments in Existing Equipment

    Migrate a local network to fibre while protecting your investment in existing copper-based hardware and maintaining the existing infrastructure.

  • Protect Data from Interference

    Electromagnetic interference or EMI can cause corruption of data over copper-based Ethernet links. Data transmitted over fibre optic cable however is completely immune to this type of noise, ensuring optimal data transmission.

  • Speeds Conversion

    Convert link speeds from 10Mbps to 100Mbps or from 100Mbps to 1000Mbps.

  • Reliable Data Transmission

    Considering the fact that a media converter is essentially two transceivers passing data back and forth to each other, it gives you stronger access and a smaller chance of losing any connection.

Media Converters Features


Connect 10/100/1000/10G Ethernet to fibre segments without using crossover cables.


Allows media converters to automatically recognise the current local network's speed and adjust its own setting accordingly.


Enables you to use a Small Form-factor Pluggable transceiver (SFP), either multimode or single-mode, to link the media converter to many kinds of fibre cable.


Enables the device port to automatically detect the cable type (straight-through or cross-wired).


Standalone media converters are deployed to convert one copper connection to fibre, whereas chassis-based media converters can be installed in a variety of configurations for enterprise-wide deployment.

802.3AF POE / 802.3AT POE+ SUPPORT

Power compatible PoE or PoE+ devices like access points, cameras and similar devices in areas without nearby power outlets via copper wiring.

Industry Applications

Media Converters Applications

Media Converters - Enterprise LAN Extension
    Extend LAN reach beyond the 100-meter limit of copper CATx cabling by converting links to fibre. Fibre links enable link distances of up to 80 km.
Media Converters - Security & Surveillance IP Camera Backhaul
    POE simplifies installation of IP security cameras by eliminating the need for a power circuit near the installed device. POE media converters power these devices and backhaul signals to remote data centres or operations centres.
Media Converters - Wireless Access Point Backhaul
    POE media converters backhaul WiFi data and power access points.
Media Converters - Fibre to the Desk
    With an existing data rate in the LAN backbone at 100Mbps or Gigabit speeds, fibre can accommodate high-bandwidth applications such as streaming media and voice over IP for more secure desktop connections.
Media Converters - Fibre Mode Conversion
    Convert fibre links from multimode to single-mode, and vice versa.
