How do you choose between OM3, OM4, and OM5 multimode fibers for a high - speed data center?


OM3, OM4, and OM5 are all types of multi - mode fibers, but they have different characteristics. OM3 has a bandwidth of 2000MHzkm and is suitable for 10Gbps applications over relatively short distances (up to 300 meters) . OM4 has a higher bandwidth of 4700MHzkm and can support 10Gbps over longer distances (up to 550 meters) and is also backward - compatible with OM3 . OM5 is the latest type, with a bandwidth of 28000MHz*km and is designed to support short - wave wave division multiplexing (SWDM) technology, which allows multiple wavelengths to be transmitted on a single fiber, increasing the data - carrying capacity . When choosing between them for a high - speed data center, if the distance is short (less than 300 meters), OM3 can be a cost - effective option. For distances up to 550 meters, OM4 is a better choice. If the data center plans to implement SWDM technology and requires higher bandwidth for future growth, OM5 is the most suitable .
