Only Connect: Common fiber connectors – a guide

lc.jpgWelcome to another post in the series by Nick Locke, of Nicab Ltd, who has over 15 years experience in the electronics manufacturing industry specialising in interconnection cable assembly.

This week I am going to give you an overview of common fiber connectors in use today. I get asked a lot which connectors to use and this following guide should give you an idea of what is out there and best suited to your application.

I have also spoilt you with a video guide at the bottom of this printable guide!

MT-RJ

FDDI
Used for networking applications. Duplex connector with fixed shroud, keyed.

ESCON
Used for Data and Voice network applications (Duplex)

With Fiber Optics there is much more than just the connectors as the cable is also a massive subject on its own so watch out for future blogs on the subject.
