MPO – “Multi-Fiber Push On”
MTP – “Multi-fiber Termination Push-on”
(MPO) is a fiber connector comprised of multiple optical fibers usually available with 8, 12 or 24 fibers for common data center and LAN applications. There two versions of MPO: male (with pins) and female (without pins).
(MTP) is a variant or improved version of MPO but with better mechanical and optical performance. The MTP has a removable housing which allows for re-work and re-polish hence the mechanical performance.
