Abstract
A multimode optical fiber has an equivalent modal dispersion value (DMD) of less than 0.11 ps/m for (Δλ×D)>0.07 ps/m as measured on a modified DMD graph. The modified DMD graph accounts for chromatic dispersion to ensure that the multimode optical fiber has a calculated effective bandwidth EBc greater than 6000 MHz-km when used with multimode transverse sources.
