The present invention refers to a method for configuring a radio communication channel between at least a first and a second devices wherein said devices comprise a physical data port and radio communication means, said method comprising the following steps:

Method and equipment for configuring radio communications

An optical chromatic dispersion compensation module consists of a portion of fiber () comprising a variable pitch Bragg grating and a mechanical structure () consisting of two flexible mountings (') and one fixed mounting (). The portion of fiber () is attached to said mechanical structure () at three points: A first soft mount point () is connected to the fixed mounting () and two rigid mount points (&#x2032;) are connected to the flexible mountings (&#x2032;). The module also consists of a mechanical actuator () designed to act on the mechanical structure () to compress a first portion of the Bragg grating and to stretch a second portion of the Bragg grating while keeping the central section of the grating fixed. The chromatic dispersion value produced by the Bragg grating filter is thus modified, while its central wavelength remains fixed.

The present invention relates to an optical fiber (') having at least one Bragg grating (), the fiber comprising a core () surrounded successively by cladding () and a coating (), said fiber being obtained by writing said grating in the core and/or the cladding directly through the coating which is made of a material containing an organic substance that is substantially transparent to the ultraviolet type radiation used for writing said grating, wherein the material of said coating contains an inorganic substance that is not miscible with the organic substance and that is distributed in substantially uniform manner in said material.
