1. A method of effecting an optical connection between an optical fibre of one optical cable and an optical fibre of another optical cable, which method comprises:

  • (i) mounting in a cassette a preformed component comprising a housing and at least one discrete optical conductor which is so disposed in the housing that opposite end parts of the conductor, each of which end parts consists of at least one length of optical fibre, protrude from the housing at an acute angle to one another lying in the range 0°

    to 90° and

    that at least a part of an optical signal entering said discrete optical conductor along one of its protruding lengths of optical fibre will pass along a discrete optical path and said part of the optical signal will leave said optical conductor along another of its protruding lengths of optical fibre;

    (ii) splicing one of the protruding lengths of optical fibre of the optical conductor of said preformed component to one of said two optical fibres to be optically connected and splicing another of said protruding lengths of optical fibre of said optical conductor to the other of said two optical fibres;

    (iii) providing mechanical protection for each optical fibre splice; and

    (iv) so mounting the protected optical fibre splices in said cassette that the protected optical fibre splices are spaced from said preformed component, at least one of the group consisting of the preformed component and the protected optical fibre splices being so detachably mounted in said cassette that the distance between the protected optical fibre splices and the preformed component can be reduced.
