Abstract
The invention relates to a method for establishing a connection between two optical lines, in which a spare length of light conducting fibre is withdrawn from a storage container and, after completion of the connections, pushed back in again. To reduce the space required for storage containers, it is proposed that the light conducting fibres of the optical lines to be connected should each be connected to an end of a connecting fibre which is withdrawn as needed from a single storage container and whose excess lengths are slid back into the storage container after the connections have been made.
Claims6
A storage container for receiving a detachable connecting fibre, both ends of said connecting fibre being connectable with an optical line, comprising a substantially cylindrical core having a diameter of at least 40 mm, arranged centrally between two lateral guide walls the distance h between the guide walls being in the range d.sub.o <h<1.3, where d.sub.o is the diameter of the connecting fibre, the connecting fibre being wound spirally in at least two turns in a plane around the core, the end of the outermost turn being detachable through an opening in a side wall surrounding the core at a distance, and the end of the innermost turn being detachable and being led obliquely from the winding space between the lateral guide walls and over the turns to a guide eyelet located radially outside the winding space.
