Abstract:
1. A multi-channel optical receiving module comprising: a bench; a first substrate disposed on the bench, the first substrate having grooves; optical fibers disposed in the grooves of the first substrate, respectively, the optical fibers transmitting optical signals; a first lens disposed on the first substrate to collimate the optical signals; a second substrate disposed on the bench at a side of the first substrate, the second substrate spaced apart from the first substrate; a light receiving device disposed on the second substrate, the light receiving device receiving the optical signals; a second lens disposed over the light receiving device, the second lens focusing the optical signals to the light receiving device; a mirror reflecting the optical signals between the first lens and the second lens; a block fixing the mirror inclined from a sidewall of the first substrate toward a top surface of the second substrate, the block including through-holes, and the through-holes transmitting the optical signals between the first lens and the second lens without refraction of the optical signals; a supporting frame fixed to the sidewall of the first substrate; a plurality of branch frames parallel to the supporting frame, the branch frames fixing the mirror; and a plurality of side plates connecting the supporting frame to the branch frames.
