What are the polarities of duplex fiber jumpers?
To help the industry select and install the right components to maintain proper polarity, TIA-568-C standards recommend the A-B polarity scenario for duplex patch cords. The A-B duplex

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
The FOA Reference For Fiber Optics
Since most fiber optic links use two fibers transmitting in opposite directions to create a full duplex link, you need to ensure that transmitters are connected to receivers and vice versa.

Stop Drawing Fiber Polarity—Start Mapping It with Symbols Instead
Two of our fiber experts carefully explain these upcoming changes, walk you through the new symbols and describe in detail what these changes mean for you and your fiber projects.
Polarity Basics
The fiber holes in the body of the connector are numbered in order (from left to right). Each of the connectors is marked with a white dot in order to designate the positions when plugged in.
Fiber Polarity: Everything you Need to Know
When looking at the fiber end-face, fiber positions are numbered from left to right starting with P1. The P1 position is also commonly marked with a white dot on the side of the connector
