Panduit NKFEI 1-Port Coupler Module with F-Coaxial Connector, Electric Ivory

this is the 43rd lecture in the fo a series of lectures on fiber optics in this lecture we're going to talk about the polarity of MPO ray connectors and we're going to talk about how you can manage the polarity of these connectors using pandu it's pan MPO connector as you probably know the MPO connector is designed as an array connector with 12 fibers in a row as shown here or multiple rows of 12 fibers although the standard allows for up to six rows or 72 fibers it's very unusual to see anything other than one or two rows 12 or 24 fibers and one of these connectors when you mate two of these connectors the Farrell's are aligned by alignment pins one connector will have pins the other connector will have holes and when they mate that's supposed to align the fibres accurately enough to have low loss MPO connectors are also keyed the key is there because when you make two connectors you h
