DMD Specifications (ps/m maximum) The fiber shall meet at least one of the following DMD templates, each of which consists of both an inner and outer mask specification, and the sliding mask specifications shown below. OM1, 2, 3, and 4 Fibre Classifications The larger core means that multiple modes of light travel down the core at the same time, thus the name "multimode." Legacy Fibers Importantly, OM1's 62.5 µm core size means that it is not compatible with other grades of multimode and cannot accept the same connectors. Standard Step index fiber is rare - only POF uses a step index design today. However, the modes tend to disperse over longer lengths that the transmission distance of MMF is limited. These positioning systems are the upper alignment segments of Newport's Single-Mode Fiber Coupler systems, useful for multimode fiber coupling.
