An optical fiber coupler includes a receiving interface and two lenses. The receiving interface is configured for matching and connecting to an external optical fiber of a particular diameter within a range of 62.5 μm to 100 μm, and for receiving optical signals from the external optical fiber. The two lenses are configured for coupling the received optical signals. A distance between the two lenses falls within a range from 0.5 mm to 0.95 mm. A curvature radius of each of the two lenses falls within a range from 0.3579 mm to 0.3898 mm. |
