1310/1550nm polarization maintaining three (four) port fiber ring resonator
Polarization maintaining (PM) fiber optic circulators are irreversible unidirectional three port devices that have wide applications in a large number of optical equipment and many occasions. Our polarization maintaining optical circulators have center wavelengths of 1064, 1310 (O-band), or 1550 nanometers (C-band). In addition, these polarization maintaining fiber circulators are available with or without connectors, FC/PC connectors, or FC/APC connectors. Optical circulators are three port devices, and light can only propagate in one direction. If the signal is input from port 1, it is output from port 2; And if the signal is input from port 2, it will be output from port 3, with very low output loss. When light is input from port 2, there is a significant loss when output from port 1. Similarly, when light is input from port 3, there is also a significant loss when output from ports 1 and 2. Optical circulators are irreversible optical devices. Due to its high isolation and low insertion loss, fiber optic circulators are widely used in advanced communication systems, such as add/drop multiplexers, bidirectional pumping systems, and dispersion compensation devices. High power fiber ring resonator is an improved product developed on this basis. Xiaoxiao Photon can customize a wide range of wavelengths and can withstand high power, including (850, 980, 1018, 1053, 1064, 1310, 155...)
