1030nm 50mW PM Faraday-Based Isolator

Overview

The FT-1030-9 is a Faraday-based PM isolator centered at 1030 nm with a 50 mW continuous power rating, built on PM980 fiber. Minimum extinction ratio reaches 20 dB with both axes working and 22 dB in fast-axis-blocked configurations, preserving polarization purity for PM laser chains. Single- and dual-stage options allow isolation to be matched to the application. Return loss of 50/50 dB and operation from -5 to +50 °C suit demanding laboratory conditions, while the 5.5 x 35 mm package keeps the footprint small. It is intended for fiber lasers, test instruments, fiber sensors and research systems built on polarization-maintaining fiber.
