Shenzhen Optico Communication Co., Ltd. is one of the most credible manufacturers and suppliers of 3 port conventional fiber circulator in China. Please feel free to wholesale high quality customized products at competitive price form our factory. If you have any enquiry about free sample, please feel free to email us.
When light is input from port 1, the light is output from port 2 almost without loss;
When light is input from port 2, the light is output from port 3 almost without loss;
When the light is input from port 2, the light will be output from port 1 with great loss;
When the light is input from port 3, the light will be output from port 2 and port 1 with great loss.The fiber optic circulator is a non-reciprocal device, which means that any change in properties caused by light passing through the device cannot be retained when passing through the opposite direction.
