The 10G XFP multi-mode optical module transceiver supports two types of multi-mode
optical fibers with different cores. Table 6-57 shows 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 fiber is required, you need to purchase it additionally.
