Abstract: A multi-port optical node is disclosed. The optical node is configured to send and receive optical and radio frequency data signals over a data distribution network. The data signals enter and exit the node through cables connected to ports of the main housing of the node. The main housing has a plurality of slots configured to accept a plurality of electronic modules. The electronic modules provide the basic functionality of the optical node including the power supply and transmitters and receivers for sending, receiving and converting of data signals. The electronic modules are approximately all the same size thus they can occupy any of the slots of the main housing. The modules further can be monitored and controlled via a serial system bus.
