MPO Trunk Cables feature MPO connectors on both ends. MPO (Multi-Fiber Push On) is a multi-fiber connector that features 8, 12, or 24 fibers in a single ferrule, enabling high-density implementation of newer high-speed LAN and data center applications. MPO fiber optic cable assemblies provide over 12 times the fiber density in the same footprint as ordinary LC or SC cables. These high-density MPO patch cords offer significant space savings, while simplifying network installations.
MPO Connectors:
Each MPO fiber optic cable assembly must specify a type and gender of the MPO connectors. Most popular MPO connectors have 8, 12, 16, or 24 pins. For example, 12-fiber MPO patch cables are generally used for 10G or 40G applications, while 8-fiber and 24-fiber MPO patch cables are used for 100G applications. There are also newer kinds of 16 and 32 MPO connectors available for 400G and 800G applications.
To achieve ideal alignment with other MPO cables and equipment, MPO connectors utilize two alignment pins on one connector and two holes on the opposite connector. These are also referred to as “male” (with pins) and “female” (without pins) genders.
MPO Cable Application Configurations:
MPO Polarity:
To ensure data is being transmitted correctly across fiber links, the transmit signal (Tx) at one end of the cable must match the equivalent receiver (Rx) at the other end. MPO polarity scheme’s objective is to assure this continuous connection, which gets slightly more complicated when dealing with multi-fiber components. Industry standards call for three different MPO polarity methods: Method A, Method B, and Method C.
