Ridgemount Technologies Ltd offers a unique range of multimode 1xN couplers. The 1×3, 1×4, 1×5 devices support wavelengths at 850nm or 1300nm, providing low insertion loss and high directivity. These components are made by fused biconic taper (FBT) fusing process. They ensure consistent quality, reliability and performance.
Fibre sizes 50/125 and 62.5/125 multimode fibres (OM1, OM2 & OM3) configured to different coupling ratios are available.
All OM3 products are tested using VCSEL lasers at the appropriate wavelength for the application.
