1. A system, comprising:
a first transceiver that comprises:
a clock data recovery (CDR) circuit configured to receive communication data from a switch, and to manage a lookup table for equalization of the communication data; and
a first driver circuit communicatively coupled to the CDR circuit and configured to generate an electrical signal associated with the communication data, wherein the CDR circuit is further configured to tune one or more weights of one or more hardware components of the lookup table such that the communication data satisfies an optical communication quality metric; and
a second transceiver that comprises:
a second driver circuit, communicatively coupled to the first transceiver, that is configured to receive the electrical signal from the first transceiver and to modulate a laser source based on the electrical signal to generate an optical signal via the laser source.
