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.
