Nowadays the need for high speed data transmission is still growing. In data centers multimode fibers are commonly used, OM4 fibers are in favor because of its large bandwidth. Qualification of these fibers is very important. The optimal choice of measurement components is essential to guarantee proper fiber qualification. This article describes a method to choose the best (commercially) available detector to measure the ‘Effective Modal bandwidth’ (EMB) of OM4 fibers.
