Dispersion isn’t listed as a transmission characteristic because transmission characteristics are the fixed properties that quantify how a fiber handles a signal: bandwidth, attenuation, and return loss. Bandwidth describes the usable frequency range and thus the potential data rate, attenuation measures how much power is lost per distance, and return loss indicates reflections due to impedance mismatches that can degrade the signal. Dispersion, on the other hand, is about how different spectral components of a pulse travel at different speeds, causing the pulse to broaden over distance. This spreading creates distortion and timing errors and depends on wavelength and length, rather than being a single, inherent transmission property of the fiber. So while dispersion is critical for system performance, it’s categorized separately from basic transmission characteristics.
