- Datacom applications - Short to medium range distance
Graded index multimode fibers are designed primarily for short and medium distance transmission in datacom networks. They are optimized for the 850nm and 1300nm windows. Their large numerical aperture as well as their large core diameter facilitate coupling of large sources. When bandwidth needs or attenuation budgets are not significant factors it is interesting to use low cost LED operationg at 850nm or VECSELs.
