How to measure crosstalk in an optical circulator
To effectively measure crosstalk in a laboratory, use a wide-band-width oscilloscope with 20 GHz measuring bandwidth. Crosstalk in an ISL29501 application can simply be defined as a signal that reaches the detector that was not reflected from a target. This can be from parasitic electric and magnetic fields on the circuit board, decoupling and internal paths within the chip. Abstract—This paper presents the results of a crosstalk anal-ysis of four optical wavelength division multiplexed (WDM) cross-connect (OXC) topologies.
