タツタ電線 List of Products and Services

An "Optical Fiber Coupler" is a particularly representative optical fiber component used for branching and merging optical signals, as well as for combining and splitting wavelengths. Our company manufactures and sells fused fiber couplers, which are produced by heating and melting two optical fibers and then fusing and stretching them. We have focused on the development of optical fiber couplers for non-communication bands, and we own various light sources across different wavelength ranges, including LD, SLD, ASE, and SC light sources. We can accommodate a wide range of wavelengths from 405 to 2200 nm. Additionally, depending on the wavelength range and application, phenomena that do not pose issues in communication applications may arise, leading to unexpected troubles. Our track record and knowledge in resolving these issues are our strengths. 【Features】 ■ Used for branching and merging optical signals, as well as for combining and splitting wavelengths ■ Manufactured by heating and melting two optical fibers and then fusing and stretching them ■ Capable of accommodating a wide range of wavelengths from 405 to 2200 nm *You can download the English version of the catalog. *For more details, please feel free to contact us.

"FBG" refers to a fiber optic device that forms a diffraction grating within the core of the optical fiber, giving it the function of an optical filter. Since it can select the transmitted light within the fiber optic core, it serves the role of an optical filter by separating transmitted light and reflected light. Our company is one of the few manufacturers in Japan that provides consistent support from prototyping to mass production, and we also offer customization. For manufacturers who are challenging and developing new applications, we provide appropriate products in small quantities based on our accumulated know-how, ensuring reliability and quality. 【Specifications (Excerpt)】 ■ Center Wavelength ・530nm to 2100nm (applicable to single-mode fibers at each wavelength) ■ Center Tolerance ・Center Wavelength ±0.2nm ・Wavelength Range Compatible with Chirp: 1000nm to 1100nm, 1500nm to 1600nm *You can download the English version of the catalog. *For more details, please feel free to contact us.
