Coupling Single-mode Fibre(CSF)

YOFC single-mode coupled fibres are particularly developed for fused taper coupler application. Fabricated with patented Plasma Chemical Vapor Deposition (PCVD) process, YOFC coupler fibre offers excellent uniformity, precise geometry and good optical performance. Special optical structure and dual acrylate coating system ensures high mechanical strength and insensitivity to bending. This fibre is also an ideal option for application in near-infrared communication devices and sensors.
Applications

•     Optical fibre couplers, splitters and combiners
•     Component fibre for optical fibre lasers, EDFAs and DWDM system
•     Pump laser pigtails
•     Gratings
•     Fibre sensors and gyroscope
•     Low-loss fused optical devices for C/L band application

Characteristics

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