A Detailed Discussion on FEF and LFP Function of Media Converters
Today, Ethernet media converters are gaining immense popularity owing to the beneficial features they offer. The device supports communication between two or more dissimilar networks such as copper to fiber or Fiber to Copper, thus extending the geographical transmission distance. However, in such type of media converter network, if either fiber or copper link on the one side fails, the device on the other side has to work even if there is no data transmission. Also, it will not report an error to the system administrator. To overcome this challenge, far end fault or FEF and link fault pass through or LFP functions of media converter are. This post attempts to answer most questions you might have regarding LFP and FEP fiber optic media converters. Read on to know more.
What Are the FEF Functions for Media Converters?
As discussed before, FEF is a far-end fault protocol, compliant with the IEEE 802.3u standard. The FEF function on media converters helps detect faults on the fiber media converter network. If a fiber link error occurs, the media converter on one side will transmit the FEF signal to the other media converter over a fiber network. Afterward, both the links connected to the fiber link will disconnect automatically. Without the FEF media converter, it is impossible to detect any fault and troubleshoot immediately. The FEF function prevents the data from being transmitted till the fault is rectified or to wrong locations, and sends a far-end-fault signal to the media converter.
What Are the LFP Functions for Media Converter?
LFP implies link fault pass through, which means the link fault of the local side media converter is transferred to the remote side media converter. Basically, LFP monitors the copper links connected to the media converters from the local device. Even if one side of the copper link fails, the other side continues to transmit data packets but may eternally have to wait for a response from the other side. Here, the LFP function is required as it immediately sends an alert to the network administrator about the link issue, and offers a quick and efficient solution to monitor the network. So, LFP helps in data loss mitigation.
Important Consideration When Using LFP and FEF Media Converters
It is vital to keep the following things in mind while using LEP and FEF on a media converter.
When enabling the FEF and LEP functions on the media converter, use the Ethernet-to-fiber media converter as a mediator. Make sure both ethernet media converters support FEF and LFP functions.
Try to select the same media converter for the two sides of the connection.
Do not forget to test the function before implementing it on an already functional network.
Do consult networking experts for better connectivity and transmission results.
Both FEF as well as LFP functions on media converters are utmost important for diagnosing and troubleshooting network outage, and help ensure efficient network operation of the links.
