Single Mode fiber optic circulator
Introduce
Single Mode fiber optic circulator are irreversible, unidirectional three-port devices with widespread applications in numerous optical devices and various scenarios. Our single-mode optical circulators have center wavelengths of 1064, 1310 (O-band), or 1550 nanometers (C-band). Furthermore, these single-mode fiber optic circulators are available with or without connectors, or with FC/PC or FC/APC connectors. An optical circulator is a three-port device where light propagates in only one direction. If a signal is input from port 1, it will exit from port 2; if a signal is input from port 2, it will exit from port 3, with very low output loss in both cases. However, if light is input from port 2, the loss when exiting from port 1 is very high; similarly, if light is input from port 3, the loss when exiting from ports 1 and 2 is also very high. Optical circulators are irreversible optical devices. Due to their 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.
