8-core and 12-core MPO fiber optic patch cords, which is more suitable for 40G network cabling?

8-core connection is the best solution for 40G network cabling. The 8-core connection can easily realize 100% full utilization of the optical fiber of the backbone network without any other loss. The 12-core optical fiber connector is plugged into an optical module that only requires 8-core optical fiber, and there are four optical fibers that do not come in handy. Both 8-core connection and 12-core connection will occupy a place in the 40G network of the data center. Which connection method to choose the specific connection method is recommended according to the actual application and demand.
