LIEKKI® Coreless Passive Fibers

LIEKKI® coreless passive fibers are designed and manufactured to be used as end caps in fiber amplifiers and lasers. The fibers contain no core and consist only of a silica cladding which is coated by a dual layer low index acrylate. LIEKKI® coreless passive fibers are ideal for reducing back reflections from fiber ends and preventing fiber damage at the end face in high power applications.

Features

• Compatibility:
  Matching with industry standard cladding geometries 125, 250, 400, 480, 500, 600 and 900 µm
  Round, silica cladding for easy cleaving, splicing and handling

• Reliability:
  Double cladding fiber coating proven to operate up to 150˚C and in extreme humidity

Applications

• Fiber end caps for fiber lasers and amplifiers

• Reduction of back reflections

• Prevention of fiber end facet damage in high power applications
