Fiber Optic Polarity 101: A-B Polarity
A duplex patch cord with A-B polarity carries a "straight-through" position, as seen in the example below. When facing an open port in the "Keyup" position, "B" will always be on the left and "A" will always be

Fiber Polarity Basics for Duplex Applications
Fiber polarity is the direction that light signals travel from one end of a fiber optic cable (link) to the other. A link''s transmit signal (Tx) must match its corresponding receiver (Rx) at the other
