Double/Single-clad Passive Fibre(GDF)

YOFC double/single-clad passive fibre is optimized precisely to match the DC-YDF series, with low splice performance. The fibre is widely used in industrial, medical, military and other fields.
Applications

• Pulse / CW fibre laser / amplifier

• Materials processing

• Pigtail

• Fibre combiner

• FBG

Characteristics

• Precise geometry

• Low splice loss

• Low NA core to maintain excellent beam quality
