Optical adaptor for mounting to a receptacle to optically couple connectorized optical cables

An optical adaptor (100) for mounting to a receptacle (200) to optically couple connectorized optical cables (1, 2) comprises a coupling element (110) to provide a passageway (111) for inserting a respective ferrule (11, 21) of a first and a second optical connector (10, 20) terminating a first and a second optical cable (1, 2). The optical adaptor (100) further comprises a mounting element (120) to mount the first optical connector (10) to the receptacle (200), the mounting element (120) being configured to be insertable in the receptacle (200), and a fixing element (130) to fix the mounting element (120) to the receptacle (200). The mounting element (120) is formed as a hollow body to receive the coupling element (110) and configured to fix the coupling element (110) to the receptacle (200).
