Long Wavelength VCSELs Exploitation for Low-Cost and Low-Power Consumption Metro and Access Networks

Long wavelength VCSELs are demonstrated to be able to support metro and access networks in order to achieve low-cost and low-power consumption transceivers. In particular, the exploitation of discrete multitone (DMT) direct modulation allows to achieve high transmission capacities and the availability of widely tuneable MEMS-VCSELs to sustain agility, reconfigurability and colourless features of networks.
