11. The optical fiber adapter of claim 1 , wherein the shutter door comprises a material adapted to at least partially pass light visible to the human eye therethrough when in the shutter closed position.

12. A system for ensuring the correct alignment between a first body and a second body, the system comprising:

an adapter for removably aligning the first body and the second body; and

a sensory wavelength transmitted within the adapter to sense the presence of the first body, the sensory wavelength being interrupted by the first body when the first body is aligned with the second body;

wherein the adapter comprises a deflectably supported barrier comprising a material that allows the sensory wavelength to be transmitted therethrough.

13. The system of claim 12 , wherein the sensory wavelength is a laser transmitted between a projector and a receiver.

14. The system of claim 12 , wherein the adapter comprises a first receiver for removably receiving the first body, and a second receiver for receiving the second body.
