Isolators & Circulators
The OISM Series optical Isolator is a passive device that passes light in the normal direction while blocking light in the reverse direction for any state of polarization. Employing our advanced all-glass micro-optics design, it features ultra-low insertion loss, high power handling (up to 10W CW), high isolation, ultra-mini structure, and high stability. The device is RoHS compliant and Telcordia qualified, an ideal choice for applications in fiber amplifiers, pump lasers, and optical fiber sensors.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
Fiber Optical Isolator 10W 1310/1550nm: Laser source protection depends on preserving the optical budget through the complete path. The 1310nm, C Band, L Band, Special wavelength specification sets source and detector compatibility. The fiber/interface entry (SMF-28, Special) must match the connected components.
Fiber Optical Isolator 10W 1310/1550nm: Bidirectional signal routing depends on preserving the optical budget through the complete path. The 1310nm, C Band, L Band, Special wavelength specification sets source and detector compatibility. The fiber/interface entry (SMF-28, Special) must match the connected components.

Technical FAQ
Fiber Type: SMF-28, Special · Fiber Length: 0.25m, 0.5m, 1.0m, 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: 1310nm, C Band, L Band, Special. 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.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
