Claim Text:
1. An optical communication module comprising: a printed circuit board comprising a support surface and a plurality of optical-electric conversion units, the optical-electric conversion units mounted on the support surface; an optical coupling lens comprising a first surface, a top surface, a second surface, a plurality of first lens units, and a plurality of second lens units, the first surface facing the support surface, an included angle between the first surface and the second surface being 90 degrees, the first lens units positioned on the first surface, each of the first lens units aligned with a respective one of the optical-electric conversion units, the second lens units positioned on the second surface, the top surface opposite to the first surface and defining a plurality of blind holes, the blind holes being cylindrical shaped, each of the blind holes having a reflection bottom surface, an included angle between the first surface and the reflection bottom surface being 45 degrees, an included angle between the reflection bottom surface and the second surface being also 45 degrees, an optical axis of each first lens unit intersecting with an optical axis of a corresponding one of the second lens units on the reflection bottom surface, each reflection bottom surface concentrically aligned with a corresponding one of the first lens units and a corresponding one of the second lens units, the first lens units arranged in a straight line, and the second lens units are arranged in another straight line, the blind holes arranged in one row; and a plurality of optical fibers, the second surface facing the optical fibers, each of the second lens units aligned with a respective one of the optical fibers.
