Abstract

An optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer body, an inner front body accommodating the two or more LC-type optical ferrules, ferrule springs for urging the optical ferrules towards a mating receptacle, and a back body for supporting the ferrule springs. The outer body and the inner front body are configured such that four LC-type optical ferrules are accommodated in a small form-factor pluggable (SFP) transceiver footprint or eight LC-type optical ferrules are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint. A connector is released by pulling distally on boot assembly until receptacle hook is displaced from receptacle hook recess at a proximal end of connector.

Claims (28)

1. A reconfigurable optical connector for holding two or more LC-type optical ferrules, comprising:

a removable outer housing having a longitudinal bore;

at least one inner front body removably received in the outer housing longitudinal bore, the inner front body supporting two LC-type optical ferrules;

ferrule springs for urging the optical ferrules towards a mating receptacle;

a back body for supporting the ferrule springs;

a back body post configured to accept a crimp ring inserted within a proximal end of a boot assembly;

boot assembly including at least one wing configured to be received in an opening within removable outer housing for securing outer housing and front body with boot assembly; and

wherein pulling boot assembly in a distal direction displaces a receptacle hook of the mating receptacle to release the connector from the mating receptacle;

wherein the inner front body comprising top and bottom portions with open sidewalls.

2. The reconfigurable optical connector of claim 1 , further comprising a flap in the outer housing having a retainer on the inner side thereof for holding the front body to the outer housing.

3. The reconfigurable optical connector of claim 1 , further comprising a wall in the front body for separating the ferrule springs from each other.

4. The reconfigurable optical connector of claim 1 , further comprising protective tubing around fiber strands from a fiber cable secured within boot assembly at a distal end thereof.

5. The reconfigurable optical connector of claim 1 , wherein back body is configured to be secured within a distal opening of front body.

6. The reconfigurable optical connector of claim 1 , wherein the inner front body includes an alignment tab for aligning with a receiving recess on the back body.

7. The reconfigurable optical connector of claim 1 , wherein the outer housing is configured to hold four LC-type optical ferrules in two inner bodies.

8. The reconfigurable optical connector of claim 1 , wherein the outer housing is configured to hold eight LC-type optical ferrules in four inner bodies.

9. An optical cable terminating in the reconfigurable optical connector of claim 1 .

10. A method of reconfiguring an optical cable, comprising:

providing the optical cable of claim 9 ;

removing the outer housing;

inserting the inner front body, ferrules, ferrule springs, back body assembly, and boot assembly into at least one second outer housing, the second outer housing having greater or lesser optical ferrule capacity than the outer housing.

11. The method of reconfiguring an optical cable according to claim 10 , wherein the outer housing has a two-ferrule capacity and the second outer housing has a four-ferrule or eight-ferrule capacity.

12. The method of reconfiguring an optical cable according to claim 10 , wherein the outer housing has a four-ferrule capacity and the at least one second outer housing comprises two second housings, each of the two second housings having a two-ferrule capacity.

13. The method of reconfiguring an optical cable according to claim 10 , wherein the outer housing has an eight-ferrule capacity and the at least one second outer housing comprises four second housings, each of the four second housings having a two-ferrule capacity.

14. The method of reconfiguring an optical cable according to claim 10 , wherein the outer housing has an eight-ferrule capacity and the at least one second outer housing comprises two second housings, each of the two second housings having a four-ferrule capacity.

15. The method of reconfiguring an optical cable according to claim 10 , wherein the outer housing has an eight-ferrule capacity and the at least one second outer housing comprises three second housings, one of the three second housings having a four-ferrule capacity and two of the three second housings having a two-ferrule capacity.

16. The reconfigurable optical connector of claim 1 , wherein the inner front body comprising top and bottom portions with open sidewalls.

17. The reconfigurable optical connector of claim 1 , wherein the inner front body comprises a receptacle hook recess configured to receive the receptacle hook from the mating receptacle.
