Treatment methods for common faults of Media Converter

  • January 15. 2019
SFP Media Converter is commonly used for copper networks that cannot be covered, must use fiber to extend the transmission distance. It can also help optical fiber connect to metropolitan area network and the next layer network. However, there may be some failures in use, ETU sorted out some common faults and simple processing methods of media converters, let’s learn together!


1. Link light is not bright
a. Fiber Optic Patch Cord link maybe short-circuit.
b. Is the optical fiber interface properly connected?
c. Is the fiber connector inserted into the device interface perfectly? Does the Optical Patch Cord match the interface? Does the device type match the fiber type? Is the transmission distance too long to exceed the optical fiber transmission distance?


2. Network packet loss is serious
a. Does the electrical port of the media converter match the device interface?
b. To detect the twisted-pair or RJ45 Copper SFP transceivers port.
c. Does the loss of optical fiber line exceed the sensitive value of the equipment?

3. Intermittent signal
a. Maybe the optical path attenuation is relatively large, need to use optical power meter to measure the optical power of the receiving end, if smaller, can be judged as optical path fault.
b. It may be media converter fault, At this moment, both ends of the media converter can be connected to the PC (not through the switch), both ends to PING. If no problem, send a larger file(more than 100M) from one end to the other, observe its speed. If the speed is slow (files less than 200M for more than 15 minutes), can be basically judged as media converter fault.

4. Is the patch cord disconnected?
On-off detection for optical cable or patch cord: Use the laser flashlight to irradiate one end of the optical cable or patch cord, see if there's any light on the other side, If not, the optical cable is broken.

The above are some simple knowledge of fault handling for media converter provided by ETU-Link, hope this article will help you when using media converter, ETU-Link hope to grow with you!
