Fused fiber couplers and WDMs
Fused fiber couplers enable accurate splitting and monitoring of optical signals in single mode fiber. Casix high performance components are available in a wide variety of tap ratios, wavelength ranges, packaging sizes and connector options.
Fused fiber WDM (Wavelength Division Multiplexing) couplers are used to combine and separate optical signals transmitted on different wavelengths. Casix fused fiber WDMs are available in common NIR and telecom wavelengths. They are an ideal solution for combining pump and signal wavelengths in fiber lasers and amplifiers or for combining telecom signals.
