Abstract: The present invention relates to an arrangement for handling optical fibers in a confined or limited space, such as connecting, reorganizing and/or cross-coupling optical fibers in a cassette without said fibers intersecting one another. By providing the cassette (4) with looping channels (17), the optical fiber cables can be organized in a controlled fashion without needing to cross. The cassette may also include elements (18, 19) which function to change the direction of the optical fibers prior to connecting said fibers.

Abstract: The present invention relates to an arrangement for handling optical fibers in a confined space, such as connecting, reorganizing and/or cross-connecting several optical fibers contained in optical fiber cables in an insulated space. Controllable organization of the optical fiber cables can be achieved, by providing the insulated space (2, 3) with cable guiding and coiling means. The arrangement includes elastic and tight transits in openings (5, 6). The transits have a tapering centre part and will adapt to optical fiber cables of mutually different diameters and allow the cables to extend in different directions outside the insulated space.
