Fiber Optic Cable Connectors

Connectors for optic cable are very different from copper and coaxial due to the nature of the transmitted signal. The male part of the connection is called “connector”, while female – “receptacle” or “adapter”. For the connections with bandwidth over 10 Gbps two fibers are used – one for sending and one for receiving. If the bandwidth is over 40 Gbps, the multimode cable need to be used which might have up to 24 fibers. Connectors differ by the type of the optic cable. The single strand fiber uses simplex connector, two strand fiber – duplex connector, and more than two strands fiber requires array connector. Simplex connectors should maintain polarity of the signal in the optic cable. This is why it is important to color-code the connectors.


The list of connectors is below:


  • MPO array connector


  • LC connector





  • Duplex SC fiber-optic connector


  • ST fiber-optic connector, still used for example in video over fiber range of products


  • Duplex ST fiber-optic connector


  • FDDI fiber-optic connector


  • FC fiber-optic connector, can be seen in regular fiber optic media converters as well as in video over fiber

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
