OPTICAL SUB-ASSEMBLY FOR A MODULE COMMUNICATING OVER OPTICAL FIBER, WITH A DEVICE FOR OPTICAL COUPLING ALIGNED IN A PASSIVE MANNER

摘要

The present invention relates to an optical sub-assembly for an optoelectronic module (M), designed to provide conversion of an electrical signal from a main electronic board into an optical signal or vice-versa. It comprises an alignment ring which allows the mechanical sub-assembly to be mechanically aligned and to be centered in a passive manner directly upon installation and hence the optical axis of the optoelectronic component to be readily aligned with the axis of the fiber optic ferrule and hence with the optical fiber extended by a complementary ferrule which is accommodated facing it in the holding cage.
