Passive Fiber

Everfoton's Double/Single-cladding Passive Matched Fiber is used for the processing,assembly, and connection of optical devices related to fiber lasers. This series of optical fiber can accurately match the double-cladding active fiber and significantly improve the splicing eficiency with the double-cladding active fiber. The multi-mode fiber with large core and high NA can be used for pumping source output and power output.

Precise geometry control
Low NA to ensure single-mode output
Lower splicing loss
