1550nm Polarization Maintaining 4-Port Fiber Circulator

Polarization Maintaining (PM) Fiber Optic Circulators are irreversible, unidirectional, three-port devices that are widely used in a wide range of optical devices and applications. Our PM optical circulators are available with center wavelengths of 1064, 1310 (O-band), or 1550 nm (C-band). In addition, these PM optical circulators are available with connectorless, FC/PC, or FC/APC connectors. Optical circulators are three-port devices that can only propagate light in one direction. A signal input at port 1 will be output at port 2, and a signal input at port 2 will be output at port 3, with very little loss. Light input at port 2 will be lost when it is output at port 1, and light input at port 3 will be lost when it is output at both ports 1 and 2. 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. High-power fiber circulator is an improved product developed on this basis. Idealphotonics can customize a wide range of wavelengths and can withstand high power, including (850, 980, 1018, 1053, 1064, 1310, 1550, 1650nm, etc. Some wavelength powers can meet 5~10W power and polarization-maintaining (PM) fiber optical circulators.
