Singlemode 1310 1550nm Fused WDM

Fused WDM

Fiber Optic Fused WDM Coupler (Wavelength Combiner/Splitter, Wavelength Selective Coupler or Dichroic Coupler) is based on Fused Biconical Taper (FBT) technology, it is used to combine and separate optical signals transmitted on different wavelengths. Compare to the filter type WDM (FWDM device), fused WDM offers low insertion lose and much lower price and it is widely used in optical transmission network and network status monitoring.

KINSOM’s Fused WDM couplers are available in a wide variety of configurations, wavelength ranges, housing and connector options, and can therefore be readily specified in a wide variety of applications, enabling rapid design cycles and new project builds. KINSOM also offers modular assemblies that integrate other components to form a full function module or subsystem. These Optical Fusion Couplers are particularly well suited for harsh environments and meet or exceed Telcorida GR-1209-CORE and GR-1221-CORE reliability requirements.
