Principle of Three-Terminal Optical Circulator
An optical circulator is a three- or four-port designed such that entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1 but. These non-reciprocal devices route light from one port to another in a unidirectional manner, ensuring efficient signal transmission and reception.

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.

Huawei checks the light and signal reception of optical modules
Log in to the switch through Telnet or console port to check the switch model. This document describes the principles and configurations of the Device Management features, and provides configuration examples of these features. During use, reading optical module information helps understand its real-time operating status, enabling faster troubleshooting of link abnormalities. Run the display transceiver [interface interface-type interface-number | slot slot-id] , to view the information on. How to Configure Optical Ports on Huawei S5720-32P-EI-AC Switch?
