Step-index Multimode Fiber 105/125 VIS-IR, 200/240 VIS-IR

j-fiber’s Step index Multimode fibers have been specifically developed for high performance and stability in demanding laser, medical and industry applications, featuring high fiber strength and superior fiber geometry. j-fiber step index fibers VIS-IR are based on j-plasma performs, have a step index profile, an undoped core and a fluorine doped cladding. They are available in two fiber design options, 105/125 VIS-IR and 200/240 VIS-IR and various numerical apertur levels.
As an option the fiber is also available with high OH content for UV-VIS range application.
