Lightel’s (N+1)×1 Polarization Maintaining (PM) pump combiners are designed to combine one or more pump laser beams using multimode fiber and one signal beam on PM fiber into one PM output optical fiber with dual cladding. The device features high Polarization Extinction Ratio (PER) and pump efficiency and is available in (1+1)×1, (2+1)×1, (6+1)×1 and custom configurations.
Features
- High PER
