This document describes a circuit designed to improve optical communication by reducing power consumption and increasing transmission rates. The circuit uses lasers and optical fibers to transmit digital or analog signals with low error rates. It works by converting electrical signals to optical pulses using a laser, transmitting the pulses through optical fibers, and then converting them back to electrical signals. By switching to optical fiber transmission, the circuit avoids issues like noise, signal loss over long distances, and interference from electromagnetic fields. It further optimizes the system using techniques like pulse amplitude modulation and assigning more bits to represent lower probability values to reduce power usage.
