Patent ID: 7167653

Claim:
An optical transceiver comprising: (a) a substrate; (b) a transmitter section formed on the substrate; the transmitter section including a light-emitting element; (c) a receiver section formed on the substrate to be close to the transmitter section; the receiver section including a light-receiving element; (d) a conductive first connection member fixed near the substrate; the first connection member having a first opening that allows a first light beam from the light-emitting element to penetrate the first connection member; the first opening being aligned to an optical axis of the light-emitting element; the first connection member having a second opening that allows a second light beam toward the light-receiving element to penetrate the first connection member; the second opening being aligned to an optical axis of the light-receiving element; and (e) a transparent second connection member fixed near the first member in such a way as to shut the first opening and the second opening of the first connection member at a front of the first connection member; the first light beam from the light-emitting element propagating through the first opening and the second connection member; the second light beam toward the light-receiving element propagating through the second connection member and the second opening.
