Product details
Overview
The FT-1080-4 is a TGG-based optical isolator for 1080 nm non-PM fiber links, rated for 300 mW of continuous-wave power. The terbium gallium garnet rotator delivers stable Faraday rotation at this wavelength, blocking reverse light that would otherwise feed back into the source. Forward insertion loss is kept low while the reverse path is strongly attenuated. Beyond the CW rating, the device also tolerates high peak powers from nanosecond pulses. It fits fiber laser seed stages, sensor interrogators and test instruments where moderate power and reliable isolation matter more than raw wattage.
