3. An optical fiber receptacle adaptor according to claim 2 , wherein the first locking portion and the second locking portion are lockable to the optical fiber receptacle adaptor by a formfitting locking mechanism.
4. An optical fiber receptacle adaptor according to claim 3 , wherein the receptacle end comprises at least one undercut slot and each of the first locking portion and the second locking portion comprises at least one protrusion having a surface complementary to the undercut slot, wherein the undercut slot of the optical fiber receptacle adaptor receives the protrusion of the at least one of the first locking portion and the second locking portion and is locked therewith.
5. An optical fiber receptacle adaptor according to claim 4 , wherein the undercut slot of the optical fiber receptacle adaptor receives the protrusion of both the first locking portion and the second locking portion and is locked therewith.
6. An optical fiber receptacle adaptor according to claim 4 , wherein the undercut slot of the optical fiber receptacle adaptor and the respective protrusions of the first locking portion and the second locking portion are substantially cylindrically shaped.
7. An optical fiber coupling system comprising:
an optical fiber receptacle having an optical ferrule receiving portion, and
an optical fiber receptacle adaptor having
a single-part housing comprising a receptacle end having an opening and a plug receiving end, the receptacle end adapted for securing to the optical fiber receptacle and for inserting therein and receiving the optical ferrule receiving portion of the optical fiber receptacle, and the plug receiving end adapted for inserting therein and receiving an optical ferrule and for urging the optical ferrule into communication with the optical ferrule receiving portion of the optical fiber receptacle, and
a locking module for securing the single-part housing to the optical fiber receptacle, wherein the locking module comprises a top surface including a protrusion opening for accommodating a vertical protrusion of the optical fiber receptacle.
8. An optical fiber coupling system according to claim 7 , wherein the locking module comprises a first locking portion and a second locking portion, the first locking portion and the second locking portion are each engageable with the optical fiber receptacle adaptor, and define, when engaged with the receptacle adaptor, a through-hole between the first locking portion and the second locking portion for engaging the optical fiber receptacle.
9. An optical fiber coupling system according to claim 8 , wherein the first locking portion and the second locking portion are lockable to the optical fiber receptacle adaptor by a formfitting locking mechanism.
10. An optical fiber receptacle adaptor according to claim 9 , wherein the receptacle end comprises at least one undercut slot and each of the first locking portion and the second locking portion comprises at least one protrusion having a surface complementary to the undercut slot, wherein the undercut slot of the optical fiber receptacle adaptor receives the protrusion of the at least one of the first locking portion and the second locking portion and is locked therewith.
11. An optical fiber coupling system according to claim 10 , wherein the undercut slot of the optical fiber receptacle adaptor receives the protrusion of both the first locking portion and the second locking portion and is locked therewith.
12. An optical fiber coupling system according to claim 10 , wherein the undercut slot of the optical fiber receptacle adaptor and the respective protrusions of the first locking portion and the second locking portion are substantially cylindrically shaped.
13. An optical fiber coupling system according to claim 8 , wherein the optical fiber receptacle comprises a collar portion extending from a flange portion thereof, the collar portion extending through the through-hole defined between the first locking portion and the second locking portion of the locking module when the locking module is engaged with the optical fiber receptacle adaptor, thereby securing the optical fiber receptacle adaptor to the optical fiber receptacle.
14. An optical fiber coupling system according to claim 13 , wherein respective matching surfaces of the first locking portion and the second locking portion surrounding the through-hole, when the first locking portion and the second locking portion are engaged with the optical fiber receptacle adaptor, are recessed, the recessed surfaces accommodating the flange portion of the optical fiber receptacle when the locking module is engaged with the optical fiber receptacle adaptor.
15. An optical fiber coupling system according to claim 8 , wherein first locking portion and the second locking portion are lockable to the optical fiber receptacle adaptor by one of a snap and a clip mechanism.
16. A method for assembling an optical fiber coupling system, the method comprising:
inserting an optical fiber receptacle into a receptacle opening at a receptacle end of an optical fiber receptacle adaptor having a single-part housing comprising a plug receiving end and the receptacle end having the receptacle opening; and
securing the optical fiber receptacle to the receptacle end by attaching a locking module to the receptacle end, wherein the locking module comprises a top surface including a protrusion opening for accommodating a vertical protrusion of the optical fiber receptacle, thereby assembling the optical fiber coupling system.
