"4Power"

Introduction

Injection of high optical power from lasers into fibers is a problem with standard connectors.
Slight misalignment, non optimised focus point, poor spot quality are causes of fiber and connector destruction.
Standard connectors with epoxy around the fiber up to the optical face are burning easily.
For high power injection the fiber end must not be in contact with epoxy or metal.
Consequently several connectors solutions have been developed, like “4Power”.

   
 
 

Design

"4Power" is a connector for very high power laser delivery systems used in industrial or medical applications and compatible to the Mitsubishi standard.

The technology derives from the “high power SMA” connector with a free standing fiber end creating an air gap between the fiber and the metallic ferrule.
A number of improvements have been made for better heat dissipation.
The ferrule is larger than the SMA with a 4 mm diameter allowing fibers up to 1000 µm, the material of the ferrule is copper and the body of the connector forms a radiator.

Besides the connector allows SEDI-ATI’s crimp and cleave special assembly technology which has much better performances than polishing.

The connector can be supplied with or without indexation as well as electrical continuity with the metallic tube of the patch cord if required.

 
 
 

Assembly

The most difficult part is the way to assemble the connector to the fiber (end face quality, stress, gluing, cable retention, etc.). Consequently these connectors are not proposed as a discrete component but only assembled (pigtailed or as patchcord). 

These high power assemblies can be made with 200μm to 1000μm core fibers. 
Special design on request.
