This is a polarization maintaining isolator with a dual stage configuration and operating at 1550nm wavelength. This fiber optic isolator has input and output polarization maintaining fibers. It is often used to block light traveling in the backward direction, preventing instability and damage to a laser system caused by back reflection.

Employing proprietary micro optics design, this polarization maintaining optical isolator features low insertion loss, high optical power threshold, perfect isolation with high extinction ratio. It comes in a compact packaging that ensures stable and reliable performance.

The outstanding performance parameters of this dual stage fiber optic isolator renders it the perfect choice for application in fiber amplifier systems, amplified spontaneous emission systems and optical fiber sensors.
