Ultra-small form factor optical connectors used as part of a reconfigurable outer housing

1. A reconfigurable outer housing for holding two or more connectors, comprising:

the reconfigurable outer housing having a front end and a rear end and a plurality of ports that open through at least one opening in the front end,

each port configured to releasably accept at least either of: one connector of a first type and one connector of a second type;

wherein each connector of the first type has two ferrules each with an optical fiber therein;

wherein each connector of the second type has one ferrule with a plurality of optical fibers therein; and

wherein when a connector of the first type is accepted in any of the plurality of ports, the reconfigurable outer housing is configured to expose the two ferrules thereof through the at least one opening in the front end for making an optical connection; and

wherein when a connector of the second type is accepted in any of the plurality of ports, the reconfigurable outer housing is configured to expose the one ferrule thereof through the at least one opening in the front end for making an optical connection.

2. The reconfigurable outer housing of claim 1 , further comprising a protrusion on the first connector outer housing for securing the first connector within the reconfigurable outer housing.

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

4. The reconfigurable outer housing of claim 1 , further comprising a push-pull tab on the reconfigurable outer housing.

5. An optical cable terminating in the reconfigurable outer housing of claim 1 .

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

providing the optical cable of claim 5 ;

removing the reconfigurable outer housing;

inserting the first connector into at least one second reconfigurable outer housing, and wherein the second reconfigurable outer housing having greater or lesser connector capacity than the first reconfigurable outer housing.

7. The method of reconfiguring an optical cable according to claim 6 , wherein the first reconfigurable outer housing has a two-optical ferrule assembly connector capacity and the second reconfigurable outer housing has a four-optical ferrule assembly connector capacity or an eight-optical ferrule assembly capacity.

8. The method of reconfiguring an optical cable according to claim 7 , wherein the first reconfigurable outer housing has a four-optical ferrule assembly capacity and the at least one second reconfigurable outer housing comprises two second reconfigurable outer housings, each of the two second reconfigurable outer housings having a two-optical ferrule assembly capacity.

9. In an optical connector holding two or more optical ferrule assembly having an outer body, an inner front body accommodating the two or more optical ferrule assembly, ferrule springs for urging the optical ferrule assembly toward a mating connection, and a back body for supporting the ferrule springs, the improvement comprising configuring the outer body and the inner front body such that four-optical ferrule assembly are accommodated in a small form-factor pluggable (SFP) transceiver footprint of about 14 mm by 12.5 mm, wherein the improvement further comprises substantially open sidewalls of the inner front body.

10. In an optical connector holding two or more optical ferrule assembly having an outer body, an inner front body accommodating the two or more optical ferrule assembly, ferrule springs for urging the optical ferrule assembly toward a mating connection, and a back body for supporting the ferrule springs, the improvement comprising configuring the outer body and the inner front body such that eight-optical ferrule assembly are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint of about 19 mm by 14 mm, wherein the improvement further comprises substantially open sidewalls of the inner front body.
