1×2(2×2) Single Work Polarization Maintaining Fiber Coupler
The polarization maintaining coupler is an optical device designed for polarization maintaining fiber systems. It can maintain the input polarization state while achieving maximum efficiency of light splitting or combining. This product adopts a crystal structure polarization maintaining fiber coupler (PM crystals Coupler), capable of single-axis operation (fast axis blocked, slow axis blocked, or both axes blocked). It supports wavelengths from 1030nm to 2050nm, making it suitable for various fiber lengths and different light splitting ratios. Widely used in fiber optic communication, fiber lasers, and fiber amplifiers.
