PAM4 Optical Module Principle
PAM4 is an optical modulation technique that allows for higher data rates and increased spectral efficiency compared to NRZ. In PAM4, each symbol represents multiple bits of information by varying the amplitude of the optical pulse to four distinct levels. Figure 1-1 shows the typical waveform. PAM4 is a four-level pulse amplitude-modulated signal, which can be electrical or optical. Traditionally, digital signals are encoded for transmission in two levels, 0 and 1. Previous generations of serial data standards used non-return-to-zero (NRZ) encoding, rendering bits distinct high- and. Traditionally, in photonic PAM-4 transmitters, an MZM is driven by an electrical digital-to-analog converter (DAC) with an electrical driver, which requires energy-inefficient electronics. Implementations with nested modulators and drivers also exist, but they typically have larger footprints.

OPPC Optical Cable Principle
The OPPC cable (Fiber Optic Composite Aerial Phase Conductor) is an innovative optical cable that integrates electrical power transmission and optical fiber communication. OPPC cables are primarily used in voltage levels below 110kV, such as suburban distribution netwo ks and rural. Optical Phase Conductor (OPPC) is used as an alternative telecommunications solution when there is no existing ground wire, meaning Optical Ground Wire (OPGW) is not a viable option. This aerial cable combines fiber optic units within phase conductors, thus having a double function in the phase line and communication. OPPC makes full use of the power system's own line resources to avoid conflicts with the outside environment in frequency resources, routing coordination, electromagnet.
