Isolators & Circulators
1310/1550nm PM Single-Stage Optical Isolator
1310/1550 polarization maintaining single stage optical isolator is a passive device that maintains polarization while guiding light at 1310/1550 nm in the normal direction, and minimizes 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, high power handling, extremely high isolation, high extinction ratio, compact package and high stability. These Telcordia qualified components have excellent characteristics, making them an ideal choice for application in fiber amplifier systems, optical fiber sensors and instrumentation.

System integration
Integration and compatibility
Use these checks to connect 1310/1550nm PM Single-Stage Optical 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: PM1550 · Fiber Cover: 900μm Loose Tube
- 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: 1310, C Band, L Band, S 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.
