The 1550nm 3-port High Power PM Optical Circulator-30W is a compact, high performance light wave Polarization Maintaining component that routes incoming signals from Port 1 to Port 2, and incoming Port 2 signals to Port 3. So, fiber optic circulators act as signal routers, transmitting light from an input fiber to an output fiber, but directing light that returns along that output fiber to a third port.They are ideal for high power fiber laser and instrumentation applications.
The 1550nm 3-port High Power PM Optical Circulator-30W is a compact, high performance light wave Polarization Maintaining component that routes incoming signals from Port 1 to Port 2, and incoming Port 2 signals to Port 3. So, fiber optic circulators act as signal routers, transmitting light from an input fiber to an output fiber, but directing light that returns along that output fiber to a third port. They perform a similar function as an isolator, protecting the input fiber from return power, but also allowing the rejected light to be employed.
The fiber optic circulator utilizes proprietary designs and metal bonding micro-optics packaging. They’re characterized with low insertion loss, high isolation, high power handling, high return loss, excellent environmental stability and reliability. They are ideal for high power fiber laser and instrumentation applications. It is widely used in combination with fiber gratings and other reflective components in WDM systems, wavelength add/drop, Fiber Amplifier, Fiber Laser application.
If you do not see a standard circulator that meets your needs, we welcome the opportunity to review your desired specification and quote a custom circulator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.
