1053nm 300mW Non-PM Isolator (Faraday Based)

Overview

Built on a Faraday rotator stage, this 1053 nm polarization-insensitive isolator is rated for 300 mW of continuous-wave power. Typical peak isolation reaches 35 dB for the single-stage version and 52 dB for the dual-stage version, with typical insertion loss of 1.8 dB and 2.8 dB respectively. Return loss is 50 dB at both ports and polarization-dependent loss stays within 0.15 dB. The device covers 1053 plus or minus 5 nm, operates from -5 to +50 °C, and ships in a 5.5 by 35 mm package with Hi1060 pigtails. It suits MOPA fiber lasers, test instruments and research setups needing a documented guard device between source and load.
