Claim Text:
1. A data communication system, the system comprising: a network interface device comprising: a first optical communication interface configured to receive an optical signal transmission transmitted over an optical communication link, the optical signal transmission being characterized by a signal level and a noise level, the optical signal transmission being received from a transmitter device; a photodiode configured to convert the optical signal transmission to an electrical signal transmission; a TIA configured to amplify the electrical signal transmission; a processor configured to calculate a set of threshold levels based on at least the signal level and the noise level, the processor being configured to generate a set of power transmission levels for the transmitter device, the power transmission levels being based on at least one of the threshold levels, the power transmission levels being non-equispaced; an encoder for encoding the power transmission levels; a second optical communication interface for sending the encoded power transmission levels to the transmitter device; and a leaf spine network architecture comprising a top of a rack switch.
