Abstract

An optical transceiver includes a substrate, a transceiver module, an optical lens and an adhesive. The transceiver module is disposed on an outer surface of the substrate. The optical lens is disposed on the outer surface for guiding light to the transceiver module. The optical lens defines a contact surface and at least one hole. The contact surface faces the outer surface, and an opening of the hole is located on the contact surface. The adhesive is accommodated into the hole from the opening, and the contact surface of the optical lens is adhered to the outer surface of the substrate by an adhesive.

Claims

1. An optical transceiver, comprising:

a substrate;

a transceiver module disposed on an outer surface of the substrate; and

an optical lens disposed on the outer surface for guiding light to the transceiver module, and the optical lens having a contact surface facing the outer surface and arranging a hole with an opening of the hole connecting to the contact surface;

wherein an adhesive fully or partially fills in the hole allowing for the contact surface of the optical lens to be adhered to the outer surface of the substrate by the adhesive.

2. The optical transceiver according to claim 1, wherein a top surface of the optical lens is opposite to the contact surface, the hole of the optical lens extends through the optical lens, and two ends of the hole respectively connect to the top surface and the contact surface.

3. The optical transceiver according to claim 1, wherein a diameter of the hole is from 0.5 mm to 2.0 mm.

4. The optical transceiver according to claim 1, wherein the optical lens comprises a reflecting portion, a covering portion with a lateral surface, and a contacting portion protruding from the lateral surface with the contacting portion defining the contact surface and the hole.

5. The optical transceiver according to claim 4, wherein the optical lens further comprises another contacting portion protruding from another lateral surface of the covering portion.

6. The optical transceiver according to claim 4, wherein the contacting portion protrudes from the lateral surface along an extending direction, and the extending direction is orthogonal to a normal direction of the outer surface of the substrate.

7. The optical transceiver according to claim 4, wherein there is a distance between the contacting portion and an edge of the substrate.

8. The optical transceiver according to claim 4, wherein both the covering portion and the contacting portion are made of light penetrable material.

9. The optical transceiver according to claim 4, wherein a bottom surface of the covering portion faces the outer surface of the substrate, and a gap space exists between the bottom surface and the outer surface of the substrate.

17. The optical transceiver according to claim 1, wherein the hole is surrounded along its length and is configured to cause the adhesive to at least partially fill the hole based on capillary action.

10. An optical lens of an optical transceiver, adhered to a substrate of the optical transceiver by an adhesive for guiding light to a transceiver module of the optical transceiver, comprising a contact surface adhered to the substrate and a hole for the adhesive to be fully or partially filled, with an opening of the hole connecting to the contact surface.

11. The optical lens according to claim 10, wherein a top surface of the optical lens is opposite to the contact surface, the hole of the optical lens extends through the optical lens, and two ends of the hole respectively connect to the top surface and the contact surface.

12. The optical lens according to claim 10, wherein a diameter of the hole is from 0.5 mm to 2.0 mm.

13. The optical lens according to claim 10, wherein the optical lens comprises a reflecting portion, a covering portion with a lateral surface, and a contacting portion protruding from the lateral surface, the contacting portion defines the contact surface and the hole.

14. The optical lens according to claim 13, wherein the optical lens further comprises another contacting portion protruding from another side of the covering portion.

15. The optical lens according to claim 13, wherein the contacting portion protrudes from the lateral surface along an extending direction, and the extending direction is parallel to a normal direction of the lateral surface.

16. The optical lens according to claim 13, wherein both the covering portion and the contacting portion are made of light penetrable material.
