An optical assembly comprising (10) an optical coupler (12) defining a coupler first end section (18), a substantially opposed coupler second end section (20) and a coupler intermediate section (22) therebetween; a coupler passageway (24) extending in the coupler intermediate section (22) and also through at least a portion of the coupler second end section (20) and defining a passageway second end aperture (30) leading into the coupler passageway (24); a coupler peripheral surface (26) extending peripherally to the coupler passageway (24) in the coupler intermediate section (22); and a coupler lateral aperture (28) extending between the coupler passageway (24) and the coupler peripheral surface (26) in the coupler intermediate section (22). A first end optical fiber (14) is optically coupled to the optical coupler (12) in the coupler first end section (18) for allowing propagation of light between the optical coupler (12) and the first end optical fiber (14). An inside optical fiber (16) extends through the coupler lateral aperture (28) and at least part of the coupler passageway (24) in a direction leading toward the passageway second end aperture (30). |
