HFAN-09.1.0: Impact of Transmitter RIN on Optical Link Performance


Abstract: This document presents a brief overview of how RIN impacts the sensitivity of a fiber optic link followed by a summary of how RIN may be measured as outlined in the Fibre Channel standard. An alternate method is then presented in which RIN is measured in the time domain using a high speed sampling oscilloscope. There are specific advantages to performing RIN measurements in the time domain not achievable when employing a broadband power meter.
