    Abstract: A coupling structure for coupling optical radiation, i.e., light, between an optical fibre and an optical device, e.g., a laser diode or a photodiode. The coupling structure has an optical through-via which guides the optical radiation to or from the optical fibre. Light exiting the fibre travels through a guidance channel so it remains substantially confined to a narrow optical path that mimics the fibre core. Conversely, light enters the fibre after having traveled through the guidance channel. The guidance channel has a first core region, the "channel core", having first refractive index surrounded by a second region, the "channel cladding" having a second refractive index smaller than the first refractive index. The coupling structure, including the guidance channel, is preferably made of semiconductor-based material, more preferably of silicon-based material. The guidance channel is preferably silicon oxide. The coupling structure further has a fibre drive-in element, which facilitates insertion and alignment of the optical fibre to the guidance channel.

    Abstract: A modular apparatus for data communication between a distribution network and a residential network is disclosed. The apparatus has a first device adapted to interface a distribution network, at least one second device adapted to interface a residential network and to be mechanically and electrically connected to the first device, and at least one interconnecting lock adapted to keep the first device and the at least one second device firmly secured to each other and to activate electrical supply between the first device and the at least one second device.
