Matched-cladding Single-mode Fibre for Component (CSF)

YOFC matched-cladding single-mode fibre is particularly developed for optical components. The fibre offers excellent geometric and optic specifications by PCVD process. The fibre adopts special matched-cladding structure and Ge/F co-doped material system to achieve material matching, which makes the fibre can be used for taper couplers. CS1012-A and CS1013-A are suitable for light source coupled single mode output in 580- 850 nm visible band. CS1015-A and other 980/1060 nm fibres have excellent tapering performance. CS1011-A and CS1011-B are specially developed for tapered components in 1310 nm. CS1018-A and CS1018-B are specialty developed for tapered components in 1550 nm. And the macro-bending performance of CS1018-A is better than G.657A2.
Applications
  • Optical fibre couplers, splitters and combiners
  • Optical fibre lasers, EDFAs and DWDM system
  • Pump laser pigtails

Characteristics
  • Tight geometric control
  • Superior mechanical protection by dual acrylate coating system
  • Ultra-low bending loss
  • Low insertion loss
  • Low splice loss
  • Excellent consistency and reliability
