Abstract
Optical transmission apparatus, for transmission of optical signals at an optical wavelength of about 1550 nanometres, comprises: a single mode optical fibre link formed of optical fibre having substantially zero dispersion at an optical wavelength of about 1300 nanometres and a dispersion of about 17 picoseconds per nanometre-kilometre at an optical wavelength of about 1500 nanometres; and one or more dispersion compensating chirped optical fibre gratings, the aggregate dispersion of the chirped optical fibre gratings substantially compensating for the dispersion of the optical fibre link; in which the one or more gratings are coupled to the optical fibre link at respective positions substantially symmetrically disposed about the longitudinal centre of the optical fibre link.
