Fiber Optic Coupler Patents

Fiber optic coupler patents cover methods of fabrication, splitting ratios, connector designs, and protective housings for optical fibers. Key Patents and Technologies1.

Fusion-

Stretching Fabrication (US5069518A) This patent describes a method for fabricating fiber optic couplers by fusing two optical fibers along their longitudinal sections and stretching them independently under controlled tension and temperature. This process allows the propagation constants of the fibers to vary, enabling precise control of the splitting ratio over a wide wavelength range, which addresses limitations of conventional couplers that have substantial wavelength dependence (US5069518A). 2.

1xN Fiber Optic Couplers (EP0895105) This patent focuses on couplers that distribute light from a single input fiber to multiple output fibers. The invention addresses equal spacing of output fibers to achieve uniform coupling ratios. It uses a preform of concentric glass tubes to position output fibers accurately, which is critical for commercial production of 1xN couplers where N can vary (EP0895105).

3. Protective and Hardened Fiber Optic Connectors (US12111502) This patent covers fiber optic connectors and adapters designed for high-speed data transmission. It includes ferrules, adapters, and dual fastening arrangements to align and secure optical fibers, ensuring minimal signal loss.

Protective housings and strength layers (e.g., aramid yarn, steel) safeguard fibers from mechanical and chemical damage, enhancing durability in field applications (US12111502). 4. Patented Technologies and Commercial Applications Several companies, including Fujikura, US Conec, and REICHLE & DE-MASSARI AG, hold patents for fiber optic couplers and related connector systems.

These patents cover multi-fiber connectors (MTP®, MXC®), alignment systems, and cleaning technologies that improve optical performance and reliability in network installations (US Conec patents).

Summary

Fiber optic coupler patents primarily focus on: Fabrication methods: Fusion-stretching, preform assembly for 1xN couplersPerformance optimization: Controlling splitting ratios and wavelength dependenceConnector and adapter design: Ferrule alignment, dual fastening, and protective housingsCommercial implementations: Multi-fiber connectors and optical network components These patents collectively advance the precision, reliability, and scalability of fiber optic couplers for telecommunications, data centers, and high-speed optical networks.
