Subpicosecond skew in multimode fibre ribbon for synchronous data transmission

For the first time we demonstrate skew of less than 0.25ps / m across a 10-wide graded index multimode fiber ribbon. This sub-picosecond skew extends practical applications of multimode fiber ribbon to include synchronous parallel transmission with an aggregate data-rate distance product of greater than 10Gb / s ⋅km .
