For many people optical fibre is all the same and one fibre can carry the worlds data simultaneously. We can confirm this is not the case, not only is there Multimode and Singlemode but choices of each. The table below represents the range of applications and maximum working distances. However despite its detail OM4 isn't listed! This is a relatively new class of fibre that is high end multimode and pushes data carrying capability even further on the cheaper electronics.
