Couplers that can be used at 980 nm with coupling ratios of 50:50, 75:25, 90:10, or 99:1 are featured below. 980 nm narrowband couplers with a ±15 nm bandwidth offer low insertion loss performance at the center wavelength. Thorlabs offers a wide range of narrowband and wideband single mode 2x2 fused fiber optic couplers, as highlighted in Table 1. Need a product customized? We can customize our products to fit your requirements. G&H proprietary manufacturing technology provides uniquely low excess loss, along with low polarization and temperature. 1x2 Single Mode (SM) Fiber Splitters/Couplers allow for a single fiber input to be split into two outputs or for multiple inputs to be combined into one output. 1x2. Coherent Erbium-Doped Fiber Coupler (EDFC) fibers are designed for advanced optical amplifier systems.
