Fused Fiber Optic Components: Single-Mode Couplers
Applied in many fields, including avionic and space communications, biomedical instrumentation, fiber laser systems, industrial micromachining, interferometry, LIDAR, medical diagnostics, optical coherence tomography (OCT), sensing, and telecommunications, G&H's Single-Mode Couplers play a vital role in aligning and marrying individual cable fibers.
G&H manufactures a comprehensive line of fused fiber couplers for visible and NIR wavelengths using single-mode and polarization maintaining fiber. Fused fiber components possess low insertion loss and high extinction ratio, and are manufactured to exacting standards for quality and reliability.
