THE ULTIMATE LOW-LOSS MULTI-FIBER CONNECTIVITY CHOICE FOR 400G SYSTEM AND BEYOND
MPO connectors are well-suited for high-density, high-traffic applications including data centers and central offices. XFS' proprietary MPO manufacturing process employs the most advanced polishing technology for producing the MPO connectors with the best optical performance in the industry. We can offer 4, 8, 12, 24 and 48-fiber MPO assemblies, with ribbon, flat and round cable structure options. We can also provide MPO assemblies with IP (waterproof) connectivity.

Fiber Height is a critical factor for connection performance; it needs to be controlled within a certain range, and the distance between the shortest and the longest fiber as well as the variation in adjacent Fiber Heights have to be minimized to ensure good coplanarity of all fibers. XFS has set much tighter tolerances on Fiber Height than IEC to have the most consistent Fiber Heights for a perfect connection.
Core Dip is major factor in determining insertion loss and return loss of multimode MPO connector. It is a recessed area of a fiber core located at the top of the fiber. Core Dip appears during polishing process because core is usually softer than cladding material and it is easier removed. Core Dip prevents proper physical contact and needs to be minimized. XFS’ MM MPO connector has less than one-third of Core Dip value than industry average.
Geometry Limit can be used to quantitatively assess the acceptability of an MPO’s end-face. This term is a calculated merit function, which relates X-slope angle, coplanarity, and fiber tip radii in comparison to the defined ferrule compression force. For a specific MPO’s end-face condition, lower calculated values for GL indicate a better geometry. XFS has set a far more strict GL than IEC to ensure its MPO connector has the best end-face geometry and optical performance.

XFS (12c MPO)
For end-face quality, IEC guidelines allow a few defects that are small in size. XFS’ fiber optic connector is one of the very few in the industry to deliver connectors with zero defects on the ENTIRE FERRULE END FACE. Thus the connector’s light extraction efficiency is optimized.
