Isolators & Circulators
Fiber Optical Isolator 800-1060nm, up to 5W
The OIST Series fiber optical isolator is a passive device that guides lights at 850/980/1060 nm in the forward direction while blocking light propagating in the reverse direction. Our proprietary magnetic-optics technology and proven advanced micro-optics design perfected over 25 years features low insertion loss, high isolation, compact structure, high power handling, and high stability. The platform can accommodate various fibers of polarization independence, polarization maintenance, multimode, and double cladding. The available configurations include 5W CW optical power handling, dual-stage high isolation, and integrated output power monitoring tap. The tap monitor is placed before coupling into the output fiber. The excellent characteristics of this product make it an ideal choice for applications where a high-performance isolator is needed.

System integration
Integration and compatibility
Use these checks to connect Fiber Optical Isolator 800-1060nm, up to 5W 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: HI1060, HI780, SM800, HI980, PM780, PM850, PM980 · Fiber Cover: 0.9mm tube, Bare fiber, Special
- 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: 1060, 850, 980, 940, 780 · Operation Wavelength (nm): 780 / 780 / 850 / 940 / 980, 1030, 1060 / 980, 1030, 1060
- 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.
