Fiber Optic Connectors: A quick and simple guide!

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

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

MT-RJ 

MTRJ

 

 

 

Used for networking applications. It’s actually a little smaller than a standard phone jack, and just as easy to connect and disconnect. It’s half the size of the SC connector and it was designed to replace LC Connectors but that is yet to happen.

 

FDDI 
FDDI

 

 

 

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

 

ESCON

ESCON Fiber Optic Connector

 

 

 

Used for Data and Voice network applications (Duplex)

 

ST

stconnector

 

 

 

One of the most commonly used fibre optic connectors in networking applications. Cylindrical with twist lock coupling, 2.5mm keyed ferrule. For both short distances applications and long line systems.

SC

SC Connector

 

 

 

Used frequently for newer network applications. Square, keyed connector with push-pull mating, 2.5mm ferrule and molded housing for protection.

SMA

SMA905 Fiber Optic Connector

 

 

 

The SMA fiber connector is decreasing in popularity.  Used mainly in Electronics.

 

Biconic

Biconic

 

 

 

Decreasing in use.  Used in the medical device industries.

 

LC
LC-LC

 

 

 

By far the most popular connector used in the IT industry.  It has been around for years and has no signs of going away anytime soon.  It is simple and easy so likely to still be in use for years to come.

MU Connector

MU Connector

 

 

 

 

This simplex connector is not as popular LC connectors are.  This is because LC Connectors are able to be used as simplex connectors and more widely available.

 

Toslink Connector

Toslink

 

 

 

 

Toslink connectors are used in Hi-Fi and Audio Products. Delivering the highest quality of audio signal available but also simple, robust and very inexpensive.

 

With Fibre 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.
