Fiber Isolator FSI-1310P-0.3W-APC
Fiber isolators preserve source purity using the Faraday effect in magneto-optic crystals to reject reflections and permit one-way propagation, preventing backward light from degrading source, usually laser, spectral purity. JCOPTIX single-mode and PM isolators serve advanced communications/sensing, fiber sensors, laser communications, and research/nonresearch settings. Center wavelengths: 1310 nm and 1550 nm; connectors FC/APC. Contact support for customization. Single-mode isolators. Models: FSI-1310S-0.3W-APC, FSI-1550S-0.3W-APC, FSI-1550S-10W-N. Single-mode. High isolation, low insertion loss, high power. Multiple centers/powers. FC/APC. Faraday-effect isolators preserve spectral purity by blocking backward light, which may damage lasers or cause mode hops, frequency shifts, and amplitude changes. JCOPTIX high-isolation/low-loss/high-power units serve communications/sensing. Centers 1310 nm/1550 nm, bandwidth 20 nm, maximum power 0.30 W, FC/APC. A separate 1550 nm model supports 10.0 W without connectors. PM isolators. Models: FSI-1310P-0.3W-APC, FSI-1550P-5W-APC. PM type. High isolation, low loss, high power. Multiple centers/powers. FC/APC. PM fibers and micro-optics suit PM systems or devices requiring polarization preservation. Deliberately introduced birefringence is maintained axially to preserve incident polarization. JCOPTIX units serve gyroscopes, fiber lasers, fiber flow sensors, and material identification. Centers: 1310 nm/1550 nm; both FC/APC. The source calls the 1310 nm, 0.30 W unit a single-mode isolator; the 1550 nm PM unit supports 5 W.

Optical Isolator OIS9012-532 Fiber Optic Isolators U-optic
Dimensions: 12.7 mm × 12.7 mm × 12.7 mm Design Wavelength: 532 nm Material: K9 + Quartz Crystal
The optical isolator consists of a polarizing beamsplitter prism and a zero-order 1/4-wave plate, with the waveplate optical axis positioned at 45 degrees. Transmitted P-polarized light becomes circularly polarized after passing through the waveplate. After reflection and a second pass through the waveplate, it becomes S-polarized light and is reflected by the polarizing beamsplitter prism, providing optical isolation.
