Optical and electrical links are not expected to have raw, error-free performance. Using PAM4 modulation to reach 400 Gb/s speeds means that engineers must now design, develop, and validate transceivers and network communication devices that have multiple 28 or 56 Gb/s channels. With 4-level signaling and reduced signal-to-noise ratio (SNR), PAM4 links require forward error correction (FEC).
