Problem: 
What does the polarity test, on the Viavi 40G Certifier fiber testing, actually test?
Solution: 
Enterprise area fiber connections are usually duplex connections. The Polarity check is testing to ensure that the transmit fiber on one end is the received fiber on the other end and vice versa.
