Optical fiber connection base and optical fiber connection base module

An optical fiber connection base, comprising:

• a socket having:
• a base having an accommodating space;
• wherein the base is provided with an insertion hole and an alignment hole, and the insertion hole is spatially communicated with the alignment hole;
• and
• an extension portion connected to a side wall of the base;
• wherein one end of the extension portion is exposed from the base and provided with a locking hole;
• wherein a first direction extending along the insertion hole is different from a second direction extending along the locking hole;
• a light emitting module disposed in the accommodating space;
• wherein the light emitting module includes a circuit substrate and a light emitting element, the light emitting element is disposed on the circuit substrate, and a top surface of the light emitting element is exposed from the alignment hole;
• wherein a side surface of the light emitting element defines a light emitting surface, and the light emitting surface corresponds to the insertion hole;
• and
• an optical fiber bundle, one end of the optical fiber bundle being inserted into the insertion hole of the base in the first direction, such that a light receiving end is defined;
• wherein the light receiving end is adjacent to the light emitting surface, and a center of a cross section area of the light receiving end corresponds to a center of the light emitting surface.
