GAOTek 10/100Base-TX to 100Base-FX Media Converter with LFP

This media converter features 10/100 Base-TX to 100 Base-FX with LFP function, can easily track network link failure, and improves fiber-linking networks.




The GAOTek 10/100 Base-TX to 100 Base-FX Media Converter with LFP Function (Link Fault Pass-through) can easily track network link failure. The LFP function can increase the integrity and conformity of the fiber linking to simplify the maintenance of the network. This media converter is powered through external power adapters from the USB port on the hosting device such as PC or NB. This unique idea of using USB port power offers great flexibility when deploying this converter.
