Laser mode partition noise is an important source of noise in optical transmission systems operating with multimode lasers and dispersive fibres, e.g. single-mode fibres with non-zero material dispersion. The letter describes investigations which confirm the importance of considering laser mode partition noise when practical optical systems are projected. It also gives theoretical estimations and...
Twenty-six t.v. channels have been transmitted over a 1 km single-mode fibre using direct intensity modulation of a GaAlAs laser diode. The key performances of the optical link and the frequency division multiplexer are given.
