Abstract:
1. A communications network comprising: a first bidirectional serial electrical bus having a first data rate and using a predetermined electrical data protocol for coupling with a plurality of network nodes; a first interface controller coupled to the first bidirectional serial electrical bus for sampling signals received from the first bidirectional serial electrical bus at a sampling rate at least fifty times larger than the first data rate and encoding resultant sampled data into a second digital signal for transmission at a second data rate substantially greater than the first data rate; an electro-optical transmitter coupled to the first interface controller for converting the second digital signal into an optical signal at a first optical frequency for transmission over an optical fiber; an optical fiber coupled to the electro-optical transmitter for transmitting the optical signal to a remote receiver; an electro-optical receiver coupled to the optical fiber for converting the optical signal into an electrical signal; and a second interface controller coupled to the electro-optical receiver for decoding the electrical signal from the electro-optical receiver and processing the decoded electrical signal to generate a digital signal for transmission on a second bidirectional serial electrical bus using said predetermined electrical data protocol, wherein the second interface controller comprises a pre-distorter arranged to add pre-distortion to compensate for signal distortion.
