Optical module calibration RSSI
This article discusses the relationship between APD and RSSI, and introduces the basic operation of using DS1864 to improve RSSI. APD RSSI introduced that many optical modules use avalanche photodiode (APD) based optical receivers in high sensitivity applications. Abstract: This application note explains how to use the DS1864 SFP laser and diagnostics to improve the calibration of the received signal strength indicator (RSSI) for an optical receiver using an avalanche photodiode (APD). RSSI is a monitoring output that delivers an output current proportional to the average incoming optical power. The AFBR-0553Z evaluation kit is designed to evaluate the AFBR-2529SIZ with optical.
