Passive Double Clad Fibre
The YOFC passive matched double-clad fibre can realize pump source and signal optical transmission within the 1.5μm band. It features a non-polarization-maintaining design suitable for traditional high-power amplifiers, and a panda-type polarization-maintaining design suitable for high-power coherent optical communications.
