An optical communication device includes a first fiber, a second fiber, a light-emitting unit, a light-receiving unit, and a lens unit. The lens unit includes a first portion and a second portion connecting with the first portion. The first portion includes a first entrance surface, a first exit surface, and a first reflecting surface. The first entrance surface is perpendicular to the first exit surface. The first optical fiber faces the first entrance surface and the light-receiving unit faces the first exit surface. The second portion includes a second entrance surface, a second exit surface, and a second reflecting surface. The second entrance surface is perpendicular to the second exit surface. The first entrance surface and the second exit surface are coplanar. |
