at least one fiber optic coupled to the optical module.

2. The optoelectronic cable assembly as described in claim 1 , wherein a tongue portion is defined jointly by the optical module and the extending portion while the optical module interface optically and electrically with respect to a mated optoelectronic connector.

3. The optoelectronic cable assembly as described in claim 1 , wherein the optical module defines at least one spring arm abutting against a supporting face of the base portion.

4. The optoelectronic cable assembly as described in claim 1 , further comprising a metal shell which defines at least one spring piece projecting from a body section thereof, and the optical module defines at least one stopper portion abutting against the at least one spring piece.

5. The optoelectronic cable assembly as described in claim 3 , wherein the base portion defines a front face thereof, and the extending portion extends forwards from the front face, the base portion further defines a receiving portion recessed rearwards from the front face and the supporting face is disposed in the receiving portion.

6. The optoelectronic cable assembly as described in claim 5 , wherein the optical module defines a pair of guiding rails movably received in the base portion.

7. The optoelectronic cable assembly as described in claim 6 , wherein the optical module defines a main portion and a cover portion extending rearwards from the main portion, and the elastic arms are received in the main portion, and the at least one spring arm extends from the cover portion and disposed below the extending portion.

8. The optoelectronic cable assembly as described in claim 7 , wherein the guiding rails are disposed at two sides of the main portion and each connects the main portion at a front portion thereof, and a receiving room is provided between the guiding rail and the main portion.

9. The optoelectronic cable assembly as described in claim 8 , wherein the guiding rails each connects the cover portion at a middle portion thereof, and a retaining portion is provided at a free rear end thereof.

10. The optoelectronic cable assembly as described in claim 9 , wherein the base portion defines a pair of guiding slots disposed at two sides of the extending portion, and the retaining portions each runs through the guiding slot.

11. The optoelectronic cable assembly as described in claim 10 , wherein the cover portion defines at least one restricting portion coupled with the extending portion to make the optical module to be movably retained to the extending portion.

12. The optoelectronic cable assembly as described in claim 11 , wherein the at least one fiber optic is retained in the guiding rail.

13. The optoelectronic cable assembly as described in claim 12 , further comprising a pair of latching members each retained in the guiding slot and sandwiched by the extending portion and the guiding rail, and the latching members each extends into the receiving room.

14. The optoelectronic cable assembly as described in claim 13 , wherein the base portion further defines another tongue portion extending forwards from the front face and disposed in side-by-side manner with the extending portion, and a set of second contacts are retained in the tongue portion.

15. An optoelectronic receptacle connector assembly for mating with the optoelectronic cable assembly as described in claim 1 , comprising:

a second insulative housing defining a body portion and a mating tongue extending from a mating face of the body portion;

a set of contacts retained in the body portion and each providing a contacting portion exposed on the mating tongue;

a second optical module steadily retained to the body portion; and

at least one second fiber optic coupled to the second optical module.

16. The optoelectronic receptacle connector assembly as described in claim 15 , wherein the body portion defines at least one receiving hole running through the mating face thereof, and a lens member of the second optical module is received in the receiving hole.

17. The optoelectronic receptacle connector assembly as described in claim 16 , further comprising a second shell, which defines a hook portion locking into the second optical module.

18. An optoelectronic connector comprising:

an insulative housing defining a base portion;

a plurality of contacts retained to the base portion with contacting sections extending forwardly beyond the base portion; and

an optical module positioned in front of said base, back and forth moveable relative to the base portion in a front-to-back direction and intermixed with said contacting sections in a transverse direction perpendicular to said front-to-back direction; wherein

said optical module is equipped with at least one optic fiber for coupling to another optical device on a complementary connector having terminals engaged with the contacts during mating with said complementary connector.

19. The optoelectronic connector as claimed in claim 18 , wherein said optical module is equipped with a resilient device to constantly urge said optical module forwardly away from the base portion so as to be resiliently coupled to said another optical device during mating with said complementary connector.

20. The optoelectronic connector as claimed in claim 18 , wherein said optical module is an insulative piece and defines a plurality of grooves to receive the contacting sections, respectively, under condition that a back-and-forth movement of the optical module in said front-to-back direction results in a relative movement between the optical module and the contacting sections in said front-to-back direction.
