PCT No. PCT/GB92/01152 Sec. 371 Date Aug. 18, 1993 Sec. 102(e) Date Aug. 18, 1993 PCT Filed Jun. 25, 1992 PCT Pub. No. WO93/00600 PCT Pub. Date Jan. 7, 1993.Light transferred between an optical fibre housed within a fibre management unit and an optical device external to the fibre management unit. The transfer arrangement incudes an aperture formed in the fibre management unit, a mandrel mounted in the fibre management unit adjacent to the aperture and positioned so that the optical fibre lies between the mandrel and the aperture, and a probe housing the optical device. The probe is provided with an optical head in optical communication with the optical device, and with an arrangement for moving the optical head into the aperture so as to deform the optical fibre against the mandrel sufficiently to permit light to be tapped between the optical fibre and the optical head.
