Understanding Optical Signal-to-Noise Ratio

Thursday, 15 March, 13:15-14:15
Theater III, Hall B2

Session Description 

While bit error rate determines the quality of a signal, it is the optical signal-to-noise ratio (OSNR) that demonstrates if a system will meet the established BER values, even for systems operating at speeds of 40 Gb/s and higher, and complex DWDM, ROADM, and coherent fiber optic communication systems. This session will explore what OSNR is, how it is tested, the how various ITU, IEC, and other standards apply when testing next generation fiber optic communication systems.
