Fibre optic adaptor and method for optically connecting fibre optic devices together

A method of optically connecting first and second fibre optic devices together, including providing a first fibre optic device having a first fibre optic connector including a key, a second fibre optic device including at least one of a ferrule and a second fibre optic connector, and an adaptor, said adaptor including:

• a body comprising first and second receiving formations, the first receiving formation arranged to receive a first fibre optic connector, the second receiving formation arranged to receive a second fibre optic connector;
• and
• a sub-adaptor for adapting the second receiving formation to receive a ferrule;
• wherein the first receiving formation is arranged to receive the first fibre optic connector in first and second orientations and includes first and second keyways at a first end of the body arranged to receive a key located on the first connector,
• said adaptor further including at least one blocking member, wherein the blocking member is releasably attachable to the body in at least first and second positions and/or first and second orientations, wherein in said first position and/or first orientation the blocking member is arranged to block the key from accessing the first keyway and not block the key from accessing the second keyway, and in said second position and/or second orientation the blocking member is arranged to block the key from accessing the second keyway and not block the key from accessing the first keyway;
• adapting a second receiving formation of the adaptor with a sub-adaptor to receive the ferrule;
• inserting the ferrule into the sub-adaptor;
• blocking the key from accessing a first keyway formed in a first end of the adaptor, without blocking the key from accessing a second keyway formed in the first end of the adaptor, by releasably attaching a blocking member to the adaptor at a first position and/or first orientation;
• or blocking the key from accessing the second keyway, without blocking the key from accessing the first keyway, by releasably attaching the blocking member to the adaptor at a second position and/or second orientation;
• and
• inserting the first fibre optic connector into a first receiving formation of the adaptor, such that the key enters an accessible one of the first and second keyways.
