17 Jun 2021 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 fused fiber components 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 through to 2.2 µm wavelengths using single-mode (SM), polarization maintaining (PM), multimode (MM) and double clad (DC) fiber.
G&H’s fused fiber components are characterized by low insertion loss and high extinction ratio, and are manufactured to exacting standards for quality and reliability across PM, SM, MM, and DC fiber component lines.
A small selection of the G&H portfolio of fused fiber optic components are displayed below.
