Abstract:
1. A method for use in connection with installing a fibre unit into a conduit having a first end and a second end, the method being suitable to detect when the fibre unit introduced into the first end arrives at the second end, and comprising: cleaving a fibre unit to create cleaved surface of the fibre unit configured for reflecting light along the fibre unit; introducing the fibre unit into the conduit from the first end and installing it towards the second end; introducing light with a light source into the fibre unit at the first end; reflecting light from said cleaved surface; detecting reflected light caused by reflection of the light from the cleaved surface of the fibre unit, with a light detector at the first end; and detecting changes in the reflected light, whereby an operator may determine that the fibre unit has arrived at the second end.
