Method A uses straight-through MPO array cables to map the fibers the same way on each end of the link. They are connected by Type A adapters or cassettes, which have a "key-up/key-down" orientation. Polarity in fiber optic networks refers to the alignment of transmit (Tx) and receive (Rx) signals between interconnected devices. Of course in practice I usually just see people flip polarity randomly until it starts working. Or use Bi-Directional optics so you don't have to worry about polarity :) yeah, flipping them is. One of the most common faults when a newly-installed fiber network does not work is the fibers are not.
