description

SMA standard was one of the first fiber optic connector developped but the versatility of the SMA is still a great use for many industrial applications using a number of different fibers.
The SMA connector family has been adapted to most of the fibers types in diameters, coatings or specifications..
The assembly procedure also offers a variety of possibilities according to the user’s needs (crimp and cleave, glue and polishing, glue and crimp, power, sterilizable, etc.)

The so called standard SMA is in fact a puzzle designed to fit all fibers types of all different diameters, coatings and assembly solutions.
Consequently the choice must take into account the following elements:
• Ferrule : a machined metallic part adapted to the most standard fiber diameters or specially drilled for the others (from 125μm to 2mm.).The hole diameter is normally equal to the cladding diameter +5μm.
• The screw cap : round, hexagonal (or mixt on request).
• The retension : it must be adapted to the external protection of the fiber. Very simple for bare fiber or 900μm buffered, with a crimping ferrule for cables 2.5mm to 3mm., or very sophisticated for metallic protection.

   
 
 

Design & Standard

Several designs with significant differences can be found under the SMA designation.
These differences are coming from a lack of standardization between the manufacturers at the early stage of this product family.
The most popular standard used is the SMA 905 also called US SMA.

Two families are existing adapted to the different applications :
• Ceramic ferrule SMA for small fibers
• Standard SMA connectors for all diameter, all type of fiber.

OPTIONS
• Hermetic version : with viton gasket (see IP Hermetic Feedthrough) 

 
 
 

Applications

• Laser
• Industrial
• Medical
