Abstract

A fiber termination (10) for a fiber optical connection system includes a cable (107) having a number of fibers (1070) therein; a ferrule member (103) combined with the fibers, with front ends of the fibers exposed around a front end portion of the ferrule member; and a lens member (101) adhesively attached to the front end portion of the ferrule member.

Claims

1. A fiber termination, comprising:

a cable having a number of fibers therein;

a ferrule member combined with the fibers, with front ends of the fibers exposed around a front end portion of the ferrule member; and

a lens member adhesively attached over the front end portion of the ferrule member.

2. The fiber termination as claimed in claim 1, wherein a metallic shielding member encloses the ferrule member and the lens member.

3. The fiber termination as claimed in claim 1, wherein the front ends of the fibers and the front end portion of the ferrule member are polished or cleaved to be substantially flush.

4. The fiber termination as claimed in claim 1, wherein the fibers are epoxied to the ferrule member.

5. The fiber termination as claimed in claim 1, wherein a number of grooves are defined in the ferrule member to accommodate the fibers therein, and wherein adhesive material is applied to the grooves to retain the fibers.

6. The fiber termination as claimed in claim 1, further comprising two contacts and two wires connected to the two contacts, and wherein the ferrule member comprises slots in lateral sides thereof receiving the two contacts.

7. A fiber optic connection system including a plug connector and a receptacle connector, each of the plug connector and the receptacle connector comprising:

a fiber termination comprising;

a cable having a number of fibers therein;

a ferrule member combined with the fibers, with front ends of the fibers exposed around a front end portion of the ferrule member; and

a lens member either over-molded onto the front end portion of the ferrule member.

8. The fiber optic connection system as claimed in claim 7, wherein the front ends of the fibers and the front end portion of the ferrule member are polished or cleaved.

9. The fiber optic connection system as claimed in claim 7, wherein the plug connector has a cover encloses the ferrule member and the lens member.

10. The fiber optic connection system as claimed in claim 9, wherein the cover includes a rear cover attached to the cable and a front cover attached to the rear cover and the ferrule member.

11. The fiber optic connection system as claimed in claim 9, wherein two deflectable latching arms are respectively formed at lateral sides of the cover.

12. The fiber optic connection system as claimed in claim 11, wherein the receptacle connector includes a housing member defining a hollow portion to accommodate the lens member and the ferrule member therein.

13. The fiber optic connection system as claimed in claim 12, wherein two slots are defined in lateral sides of the housing member, and two hook portions are formed on the two deflectable latching arms and locked into the slots.

14. The fiber optic connection system as claimed in claim 12, wherein a clip member links the housing member and the ferrule member together.

15. The fiber optic connection system as claimed in claim 14, wherein clip member includes two arm portions spaced apart from one another and an interconnection portion connected to the two arm portions.

16. The fiber optic connection system as claimed in claim 15, wherein the interconnection portion is accommodated in a groove defined in a rear portion of the housing member, and two latching parts are formed at rear ends of the two arm portions and hold the ferrule member of the receptacle connector.

17. The fiber optic connection system as claimed in claim 15, wherein two spring members are respectively formed at the two arm portions of the clip, and two flange portions project outwardly from the lateral sides of the housing member, and wherein the housing member is mounted to an opening of a panel member, with the spring members and the flange portions disposed at opposite sides of the panel member.

18. The fiber optic connection system as claimed in claim 17, wherein the interconnection portion is received in the opening of the panel member.

19. A fiber optics connection system comprising:

a ferrule member defining a horizontal face with a plurality of upwardly open V-shaped groove sets in said horizontal face and extending through thereof a front edge face which is essentially perpendicular to the horizontal face;

a plurality of optical fibers each including a core received in the corresponding V-shaped groove; and

a lens member defining a cavity circumferentially enclosing a front edge region of the ferrule.

20. The fiber optics connection system as claimed in claim 19, further including an alignment devices to aligned said ferrule member and the lens member in a front-to-back direction along which said V-shaped groove extends.
