A network element () of a cellular telecommunications system (), the network element comprising: classification means () for assigning a classification to a user service, request () for a telecommunications service of the cellular telecommunications system; and&#x2014;assigning means () for assigning a set of class specific cell configuration parameters () that are to be used for the provision of the telecommunications service, wherein the assignment of the class specific cell configuration parameters depends upon the classification.

Cellular telecommunications system network element

An optical module comprises a support (T) on which an optical fibre (F) is mounted. Introduced on the support (T) is a V-groove (VG) that serves only to fix the fibre (F). Applied perpendicularly to the groove (VG) is a strip-shaped contact layer (CL). The fibre (F) is pressed into the groove (VG). When the fibre (F) is pressed into the groove (VG), the contact layer (CL) forms a mechanical joint with the fibre (F) in the form of a cold weld. This functions particularly well in the case of glass fibres having a contact layer of aluminium (Al). The contact layer (CL) is preferably composed of a plurality of narrow strips extending perpendicularly to the groove (VG).

Joint between fibre and support with cold weld for an optical module

The invention relates to an optical module and to method for manufacturing an optical module comprising the steps of: providing a groove in a substrate for positioning an optical component, providing the optical component, bonding the optical component to the groove by means of an aluminium-oxide bonding process, whereby an aluminium layer is formed on a lower portion of the optical component.
