Abstract

An optical wireless system useful for short metropolitan distance connections is proposed. Differently from other apparata described in literature or commercially available, our solution is completely transparent to third window telecommunication channel thanks to standard single mode optical fiber interfaces, without any electro-optic conversion. Such a system guarantees the high performances required to optical communication networks (BER, SNR and so on) without link fault and bit broadening penalties. System characterization and BER performances at 10Gbit/s, also in presence of 1.55micrometers multi-wavelength signal, are presented for connections up to 200m building-to-building roof distance. The implemented transmitter and receiver devices are compact in dimensions, very low cost and can find application not only in metropolitan network links in case of digging impediments due to time, license and cost constraint, but also in disaster recovery and local extraordinary high-bandwidth demand.
