100GHz Polarization Maintaining 1x2 DWDM Filter
100GHz Polarization Maintaining 1x2 DWDM Filter is a compact three-port PM DWDM filter designed to add, drop, separate, or combine selected ITU DWDM channels in polarization-maintaining fiber optic systems. With one common port and two branch ports, it can extract a specific DWDM wavelength from a multi-wavelength PM optical path or add a selected channel into the main transmission path while allowing other wavelengths to continue through the reflect port. Designed for 100GHz channel spacing, this PM DWDM filter provides low insertion loss, high channel isolation, stable extinction ratio, and reliable polarization-maintaining performance with PM1550 fiber. It is suitable for wavelength division systems, fiber optic amplifiers, PM fiber communication systems, coherent optical systems, fiber lasers, and polarization-sensitive test setups. Custom pass channel wavelengths, optical power levels, pigtail lengths, fiber jackets, and connector options are available.
