The production of jets in e+e- annihilation to hadrons is studied using data from the OPAL experiment at LEP recorded at centre-of-mass energies from 192 to 207 GeV. The JADE, Durham and Cambridge recombination jet finding algorithms as well as the Cone jet algorithm are employed to measure jet production rates. The measurements using the Durham and Cambridge algorithms are compared to predictions from NLO QCD predictions matched with NLLA resummed calculations to derive values of the strong coupling constant alpha_S.
