“OM5 offers a longer cabling reach than OM4.” The difference is minimal. For all the current and future multimode IEEE applications including 40GBASE-SR4, 100GBASE-SR4, 200GBASE-SR4, and 400GBASE-SR16, the maximum allowable reach is the same for OM5 as OM4 cabling. Based on application testing recently done with 40G-SWDM4 transceivers, it has been proven that OM4 could […]
