j-PFL Passive Fiber Series

j-fiber’s portfolio of passive fibers provides for maximum pump power efficiency and high-performance output power transmission in fiber laser applications. j-PFL have been designed to perfectly match with the diameter and NA of our j-fiber series of ytterbium doped double-clad active fibers. Based on our own preform design and make, we also provide customized passive fiber solutions to any of our client’s active fiber specifications.
