Doubling of the downstream rate by reusing the reflective upstream modulator is demonstrated. With just two photo-detectors, a RSOA and a power splitter at the ONU, a 20/10 Gbps mode can be provided per wavelength.
In this paper we present the different type of laser diodes that are developed at Alcatel-Thales III-V Lab in order to fulfil different functions required for radio over fibre and radar systems. The first device that is presented is a directly modulated laser with a bandwidth exceeding 20 GHz and good linearity that is used for analog wideband link. This kind of device is precious for remote delivery...
