Paper Abstract

Full coverage, wavelength switching over the entire C band on the 100 GHz ITU frequency grid, from any channel to any channel in a single microsecond, is presented here for the first time. This switching time is achieved whilst ensuring that the terminal lasing frequency is within +/- 2.5GHz of the target ITU 1 us after the switching event. The current paper presents the key parameters associated with such a laser transmitter and how these are unaffected by the addition of the wavelength switching functionality, i.e. linewidth, switching time, SMSR and transient frequency error. Next generation networks will move from physical path managed optical networks to logical wavelength managed networks where, efficient utilisation of the network on the wavelength level will be demanded. Fast and robust switching of the wavelengths is a key technological requirement for delivering on this.
