Patent ID: 8891920

Claim:
An optical assembly, said optical assembly comprising: an optical coupler, said optical coupler defining a coupler first end section, a substantially opposed coupler second end section and a coupler intermediate section extending therebetween; a coupler passageway extending in said coupler intermediate section, said coupler passageway also extending through at least a portion of said coupler second end section and defining a passageway second end aperture leading into said coupler passageway in said coupler second end section; a coupler peripheral surface extending peripherally to said coupler passageway in said coupler intermediate section; and a coupler lateral aperture extending between said coupler passageway and said coupler peripheral surface in said coupler intermediate section; at least one first end optical fibre optically coupled to said optical coupler in said coupler first end section for allowing propagation of light between said optical coupler and said at least one first end optical fibre; and an inside optical fibre extending through said coupler lateral aperture and at least part of said coupler passageway in a direction leading toward said passageway second end aperture; whereby said coupler lateral aperture allows insertion of said inside optical fibre in said coupler passageway at a location spaced apart from said at least one first end optical fibre.
