Optical Module RSSI Test

Optical Module RSSI Test

To indicate this on the module, the RSSI pin outputs a DC voltage value that varies with received RF strength. This application note explains how to use the DS1864 SFP laser and diagnostic IC to perform enhanced receive signal strength indicator (RSSI) calibration for optical receivers that use an avalanche photodiode (APD). The invention discloses a calibration and test method of burst mode light receiving power RSSI of an xGPON OLT optical module, belonging to the technical field of calibration and test of burst mode light receiving power RSSI, which comprises the following steps: s1, using a phase-locked loop. Measuring the signal strength at the receiving antenna is one way to determine the quality of a communication link.
