Abstract:
1. An apparatus comprising: a network hub having an active optical encoder, the network hub to generate a plurality of addressed optical data signals that are time-division multiplexed, each of the addressed optical data signals having an identical carrier wavelength and an address corresponding to at least one of a plurality of network nodes coupled to the network hub, wherein at least one of the plurality of addressed optical data signals comprises a plurality of data bits each encoded with the address corresponding to the at least one network node in a bit-by-bit addressing scheme in which each data bit is independently addressable and includes an entire address of a corresponding network node; an optical source coupled to the active optical encoder to provide an optical data output to the active optical encoder; a node selector comprising a microcontroller coupled to the active optical encoder to provide the address to the active optical encoder, wherein the node selector is to provide node addresses corresponding to the plurality of network nodes; and a data source coupled to the optical source, wherein the active optical encoder of the network hub is to receive a synchronization signal from the data source at a clock input of the active optical encoder and is to synchronously modulate the address onto the optical data output, wherein the active optical encoder is to dynamically change addresses for a data stream including the plurality of data bits without shifting of wavelength or reliance on network hub and network node synchronization.
