What Is MPO Connector?_
MPO (Multi-fiber Push On) is a high-density fiber optic connector that terminates 8, 12, 16, or 24 fiber strands in a single connector. MPO/MTP trunk cables are the standard method for deploying high-count fiber in GPU data centers, enabling rapid installation and reducing the number of individual cable pulls. Proper polarity management is critical.
Technical Details
MPO connectors use a precision-molded ferrule with fiber arranged in a row (or rows) at 250 μm pitch. The MTP variant (manufactured by US Conec) adds features like removable housing and enhanced spring loading for better performance. MPO connectors come in three polarity types (A, B, C) that must be matched consistently throughout the link to ensure correct signal routing. In GPU data centers, MPO-12 and MPO-24 are most common, deployed as pre-terminated trunk cables between patch panels. The trunk cables are then broken out through MPO-to-LC cassettes for individual server connections. Proper cleaning and inspection of MPO ferrule end-faces is critical due to the multi-fiber interface.
