Fiber optic isolators are passive optical components that are used to isolate returned or back reflected optical signals, thereby preventing laser output degradation. They can be found in virtually all fiber optic network systems, Erbium-Doped Fiber Amplifiers, and WDM systems, where they protect critical components from back reflection.
FOCI’s isolators are manufactured using an innovative patented design. These isolators feature ultra low insertion loss and backreflection over a wide range of temperatures, wavelengths and mechanical stresses.
FOCI’s isolators come with your choice of different packaging options to suit your needs.The isolation can be either polarization dependent or independent. Connectorization can also be specified to meet your requirements.
FOCI’s couplers are manufactured using innovative patented FBT(Fusing Biconical Taper) design. These couplers feature ultra low insertion loss and backreflection over a wide range of temperatures, wavelengths, and under mechanical stresses. They can also be independent of wavelength to suit your needs.
To provide our customers the best quality products, FOCI’s isolators are maed to conform to Bellcore’s standard
