Abstract
The invention relates to a protection for glass fibers for telecommunication with air-space paper-insulated core (H1 to Hn) in distribution fields arranged in the form of cassettes. Several air-space paper-insulated cores (H1 to Hn) are assembled according to their length in a composite element (VE1 to VE5), wherein the ends can be cut to the required length if necessary. The air-space paper-insulated cores (H1 to Hn) are assembled according to their length in a discontinued manner using connecting shaped parts or in a continuos manner along the generatrix of the air-space paper-insulated cores.

20.DEZ.2000 15:58 VJP MUNICH ~ NR.60d S.d The connection of the individual hollow leads along the curfacc lines can for example be accomp7.~.shed by melting the outer cover~.ng layer followed by compression. MuCUal gluing with thermal glues or with UV-curing glues, two-component glues or ins~.ant glues is also possible, wherein not only a discontinuouE, but aloo a continuous compo3itc can be produced. by Co-extruding multiple hollow leads, It is possible even here to produce a cox'x'ccpor~da,r~,g compooite , l0 ~,. special material combination is required in the hollow leads Suitable for such an application. A haxd but elastic plastic such as for example polycarbonate (PC) in the inner area of the tLVllow lead is especially suitable for this, so that the hollow lead does not crimp and possibly damage the glass fibers.
