Isolators & Circulators
2 μm High Power Fiber Isolator
This 2 µm passive device transmits high power light from input fiber into output fiber while blocking the unwanted light from back reflection and scattering. Leveraging our proprietary magneto-optic technology and advanced micro-optic techniques, it offers compact size, high power handling, low loss, and exceptional reliability at a competitive cost. For optical power levels below 20W, heatsink fins are utilized for thermal management, while a proprietary passive liquid cooling system ensures reliable heat dissipation for power levels exceeding 20W. We provide polarization-independent, polarization-maintaining, and custom-designed versions with integrated filter and power monitor, with support for a broad wavelength range and compatibility with specialized fibers.

System integration
Integration and compatibility
Use these checks to connect 2 μm High Power Fiber Isolator to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SMF28, SM1950, PM1950, PM 1550, 10/130DCF · Fiber Cover: Bare fiber, 900um tube, Armor cable
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 1940, 2000, 2050
- Check the Isolators & Circulators passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
