Abstract:
1. An optical communication device, comprising: a first substrate comprising a supporting surface defining a receiving cavity; a light emitting element received in the receiving cavity, and comprising a light emitting surface; a first driving chip supported on the supporting surface, and electrically connected to the first substrate and the light emitting element; a light receiving element received in the receiving cavity, and comprising a light receiving surface; a second driving chip supported on the supporting surface, and electrically connected to the first substrate and the light receiving element; a second substrate positioned between the first driving chip and the second driving chip; a coupling lens assembly connected to the first and second driving chips; a transparent bracket supported on the coupling lens assembly; and an optical waveguide comprising a light guiding portion and a fixing portion surrounding the light guiding portion, the fixing portion connected to the transparent bracket to cause the optical waveguide to be connected to the coupling lens assembly, with the light guiding portion aligning with the light emitting surface and the light receiving surface; wherein the light emitting element comprises a first light condensing lens formed on the light emitting surface, the light receiving element comprises a second light condensing lens formed on the light receiving surface, the second substrate and the first driving chip are spaced from each other, and cooperatively form a first light guiding hole between the second substrate and the first driving chip, the first light guiding hole aligns with the first light condensing lens and the light guiding portion, the second substrate and the second driving chip are spaced from each other, and cooperatively form a second light guiding hole between the second substrate and the second driving chip, the second light guiding hole aligns with the second light condensing lens and the light guiding portion.
