Gould’s Single Mode Wavelength Flattened (Broadband/Wideband) Fused Fiber Optic Couplers & optical signal splitters are small and insensitive to operating wavelengths, suitable for use in instrumentation, DWDM systems, trunk/loop branching, and CATV distribution. Their low optical loss and high directivity make them an excellent choice for systems with power constraints.
These high quality fiber optic components are manufactured using the fused biconical taper process on fully software controlled automatic fabrication stations. The process consists of placing two or more fibers adjacent to each other, then fusing and stretching them to create a central coupling region. A fused coupler is a structure formed by two independent optical fibers. Please visit our Fused Biconical Taper (FBT) page for more information.
Gould Fiber Optics uses our patented GlasSolder process for making a glass to glass bond between optical fibers and silica substrate. This technique produces a uniform “solder” bead that affixes the fiber to the substrate to provide exceptional longevity in mechanical and environmental stability.
Gould’s Single Mode Wavelength Flattened (Broadband/Wideband) Fused Fiber Optic Couplers & optical signal splitters are manufactured using Corning SMF-28® Fiber and available in various coupling ratios such as 20/40/40, 30/35/35, 33/33/33, 40/30/30, 50/25/25, 60/20/20, 70/15/15, 80/10/10, and 25/25/25/25 with operating wavelengths 1310 and 1550 nm. Other coupling ratio & wavelength options are available upon request. Available connector options are ST, FC, SC, LC, FC/APC & SC/APC.
