Isolators & Circulators
The OISM Series 1310/1550 dual stage optical Isolator is a passive device that guides light at 1310/1550 nm in the normal direction while minimizing back reflection and back scattering in the reverse direction for any state of polarization. Employing our proven advanced micro optics design, it features low insertion loss, extremely high isolation, compact structure, and high stability. These Telcordia qualified components have excellent characteristics, making them an ideal choice for application in fiber amplifier systems, pump laser diodes and optical fiber sensors.

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

Technical FAQ
Fiber Type: SMF-28 · Fiber Cover: 900μm Loose Tube, Bare Fiber. 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: 1310, C Band, L Band. 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.
