In regards to MT ferrule geometry measurements, Minus Coplanarity (or Minus-Side Coplanarity) is one way to describe how “flat” or “co-planar” an array of fibers is. To ensure minimum optical performance requirements of the telecom world, it is important to ensure that all fibers in a mated pair of connectors will have good contact.
It is intuitive that if all fibers of both ferrules are exactly on the same horizontal plane, then all fibers will likely mate well when connected.
