An optical communication module includes optical-electric conversion units, a coupling lens, and optical fibers. The coupling lens includes a first surface, a top surface, a second surface, first lens units on the first surface, and second lens units on the second surface. Each first lens unit is aligned with an optical-electric conversion unit. The top surface defines blind holes each having a reflection bottom surface. An optical axis of each first lens unit intersects an optical axis of a second lens unit on the reflection bottom surface. Each reflection bottom surface is concentrically aligned with a first lens unit and a second lens unit. Each second lens unit is aligned with an optical fiber. |
