IEC EN 61755-3 Fiber Optic Connector Test for Optical Interfaces

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61755-3 testing. This part of IEC EN 61755 defines certain dimensional limits of optical interface with cylindrical zirconia PC ferrule with 2,5 mm and 1,25 mm diameter to meet the specific requirements for fiber-to-fiber interconnect.

The performance of a cylindrical ferrule optical interface is determined by the accuracy of aligning the optical data targets of two mating ferrules with each other. There are three conditions that affect the alignment of the two optical reference point targets: Lateral aberration, angular aberration, and longitudinal aberration.

Parameters that affect the lateral and angular offset of optical fiber axes include:

• Ferrule outer diameter;
• fiber hole concentricity with respect to ferrule outer diameter;
• The fiber hole angle with respect to the outer diameter axis;
• Fiber coating diameter according to fiber hole opening;
• Alignment sleeve inside diameter;
• Fiber core concentricity according to coating diameter;
• Fiber core direction according to the switching feature.

Parameters that affect the longitudinal offset of the optical fiber axes include:

• End-face spherical radius;
• End-face spherical radius vertex offset;
• Fiber undercut;
• Axial force at the ferrule end face;
• Ferrule and fiber material physical constants;
• Alignment sleeve friction force.
