The compensating region is formed by a ribbed structure with optical fibres of a core type (3, 5). Preferably the dispersion compensating region is incorporated between two mode converters (10, 11), monolithically integrated with the compensating region. The converters are typically of a ribbed structure with variable rib width in the wave propagation direction. USE/ADVANTAGE - For high bit rate transmission in glass fibre networks, with simple, low-cost compensation in compact design.de608620patent1996-19612778
