Abstract

A modular node for an optical communication network includes one or more transceiver modules of a plurality of transceiver modules, and a node core including a plurality of electrical connectors to electrically join up to the plurality of transceiver modules to the node core. At least some of the transceiver modules has an optical transceiver configured to emit optical beams carrying data and without artificial confinement, and detect optical beams emitted and without artificial confinement. The up to the plurality of transceiver modules electrically joined to the node core are spatially separated to provide configurable coverage for optical communication based on their number and placement. And the node core further includes switching circuitry configured to connect the one or more transceiver modules to implement a redistribution point or a communication endpoint in the optical communication network.
