An optical coupling arrangement for an optical fibre (100) is made by cutting through the optical fibre, removing a wedge (9) from a first cut end (5) of the optical fibre to expose a flat face (10) that is coated with reflective material (13), and then splicing the cut ends (5, 6) of the optical fibre. This forms a notch (11) between the flat face of the first cut end and a face (6) of the second cut end of the optical fibre that is not coated by reflective material. This arrangement is straightforward to manufacture because the reflective material is applied to the cut end, rather than to a single surface of a notch in an optical fibre.
