WebTypically, a standard SM fiber has a step index profile associated with a very high alpha parameter (e.g., a > 10). The step index profile is simple, but the bandwidth at 850 nm is low. Consequently, a standard SM fiber with a step index is not suitable for MM (including few-mode) transmission at 850 nm. WebJan 18, 2024 · Thorlabs' graded-index (GRIN) multimode fiber provides lower modal dispersion and less bend loss than traditional multimode step-index fiber, with a broad operating wavelength range from 800 - 1600 nm (see the Graphs tab for attenuation plots over this range).
