The 10G XFP multi-mode optical transceiver supports two types of multi-mode optical fibers
with different cores.
lists the relationship between the core, the modal/bandwidth,
and the transmission distance. During configuration, the length of optical fibers is restricted by
the transmission distance. In addition, the optical fiber with the 50-um core and 2000-MHz*km
modal/bandwidth is a special type, which is not delivered by Huawei. If this type of optical fibers
are required, you need to purchase it additionally.
