Media Converters


Convert and Extend Signals within your Ethernet Network

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, fiber, coax). They are most commonly used to insert fiber segments into copper networks. Media converters also:

  • Extend your Ethernet network beyond the 100-meter limit imposed by copper cable
  • Integrate new technology with existing equipment to support new applications and technologies and future growth
  • Extend the productive life of your existing cabling as well as the active equipment without costly, across-the-board upgrades

Media Converters Benefits

Media Converters Features


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


Allows media converters to automatically recognize 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 fiber 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 fiber, 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


Application Extension
Enterprise LAN Extension

Extend LAN reach beyond the 100-meter limit of copper CATx cabling by converting links to fiber. Fiber links enable link distances of up to 80 km.


Application Camera
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 centers or operations centers.


Application WiFi
Enterprise - Wireless Access Point Backhaul
POE media converters backhaul WiFi data and power access points.


Application FTTD
Government & Defense - FIBER to the Desk

With an existing data rate in the LAN backbone at 100Mbps or Gigabit speeds, fiber can accommodate high-bandwidth applications such as streaming media and voice over IP for more secure desktop connections.


Application ModeConversion
FIber Mode Conversion

Convert fiber links from multimode to single-mode, and vice versa.
