Applications
An Ethernet to Fiber Media Converter can also be used where there is high level of electromagnetic interference or EMI which is a common phenomenon found in industrial plants. This interference can cause corruption of data over copper-based ethernet links. Data transmitted over fiber optic cable however is completely immune to this type of noise. An Ethernet to Fiber Optic Converter therefore enables you to inter-connect your copper-ethernet devices over fiber ensuring optimal data transmission across the plant floor.

Link Fault Pass Through (LLP. LFP) function for media converters
Link Fault Pass Through is usually used to solve the problem encountered when operating traditional media converters. The problem is this. When one side of the link fails, the other side still continues to transmit packets, and waits for a response that will never arrive.
Link status on one port is propagated to another port to notify remote nodes. If the TP port is unplugged, the converter stops transmitting over the fiber port, causing the remote fiber link to fail. LED then will show link failure on both the TP port and Fiber ports.
LFPs Status
If the fiber link fails, the converter restarts the auto-negotiation on the TP port, but stays in the link failure state. This causes remote TP link node to fail. LED also shows the link failure on both the TP and fiber ports. The figures show normal status when the link succeeds and the error status when the TP Cable A, Fiber Cable B or Fiber Cable C fails to connect.
With link fault pass through, system administrators are able to notice the link failure within a short period of time, minimizing the loss caused by this problem.
