OPTICAL COMMUNICATION DEVICE

摘要

An optical communication device includes a first fiber, a second fiber, a light-emitting unit, a light receiving unit, and a lens unit. The first fiber and the second fiber are located at two opposite sides of the lens unit. The lens unit includes a first entrance surface, a first exit surface, a first reflecting surface, a second entrance surface, a second exit surface, and a second reflecting surface. The first entrance surface is perpendicular to the first exit surface. An included angle between the first entrance surface and the first reflecting surface is 45 degrees. The second entrance surface is perpendicular to the second exit surface. An included angle between the second entrance surface and the second reflecting surface is 45 degrees. The first reflecting surface is perpendicular to the second reflecting surface. The first entrance surface and the second exit surface are coplanar.

1. An optical communication device, comprising:
a first optical fiber; a second optical fiber; a light-emitting unit; a light-receiving unit; and a lens unit, the lens unit comprising a first entrance surface, a first exit surface, a first reflecting surface, a second entrance, a second exit surface, and a second reflecting surface, the first entrance surface perpendicular to the first exit surface, an included angle between the first entrance surface and the first reflecting surface being 45 degrees, the second entrance surface perpendicular to the second exit surface, an included angle between the second entrance surface and the second reflecting surface being 45 degrees, the first reflecting surface perpendicular to the second reflecting surface, the first entrance surface and the second exit surface being coplanar, the first exit surface being opposite to the second entrance surface, and the first exit surface being parallel with the second entrance surface; wherein the light-emitting unit and the light-receiving unit are on the same side of the lens unit, the first optical fiber and the second optical fiber are on different sides of the lens unit, light emitted from the light-emitting unit irradiates the first reflecting surface through the first entrance surface and then reflected by the first reflecting surface through the first exit surface to the first optical fiber, light emitted by the second optical fiber irradiates the second reflecting surface through the second entrance surface and then reflected by the second reflecting surface through the second exit surface to the light-receiving unit, and the light-receiving unit receives the light.
