  • Abstract
    Offset QPSK is a linear modulation format exhibiting nearly constant envelop and hence may avoid nonlinear refraction effects and thus enable higher launch power and a commensurate increase in reach. We experimentally demonstrate >2dB advantage for OQPSK compared to QPSK for multi span coherent optical links using TrueWave® RS fiber.
