Single-Mode Fiber (SMF)
Single-mode fiber{.SMF} is characterized by a very small core diameter (typically $8 \, \mu\text{m}$ to $10 \, \mu\text{m}$), designed to allow only the fundamental mode ($\text{LP}_{01}$) to propagate effectively. This design minimizes intermodal dispersion, enabling extremely high bandwidth over vast distances. Standard SMF{.SMF} is usually operated around $1310 \, \text{nm}$ and $1550 \, \text{nm}$, where [material d… -

Multi-Mode Fiber (MMF)
Multi-mode fibers{.MMF} possess larger cores (typically $50 \, \mu\text{m}$ or $62.5 \, \mu\text{m}$). These fibers support multiple spatial modes) traveling at different angles. While easier to splice and couple light into, the slight difference in path lengths between the various modes) causes intermodal dispersion, limiting the effective bandwidth-distance product… -
