To meet increasing demands for high-density cabling and wider bandwidth of network applications, many data centers are migrating to the 40G and 100G Ethernet. To prepare for this change, MTP technology is applied to provide an easy migration path. Typically, a fiber optic link needs two fibers for full duplex communications. Thus the equipment on the link should be connected properly at each end. However, high-density connectivity usually requires more than two fibers in a link, which makes it...
