Gould’s Single Mode Wavelength Independent (dual window /dual band) 1X2 and 2X2 fiber optic couplers (WICs), Taps & optical splitters can be used to split light from one fiber to two or combine light from two fibers to one and provide high performance across a broad wavelength region (from 1270nm to 1600nm). WIC couplers are ideal from use in two color OTDRs, full duplex transmission on a single fiber, multi-color sensors, and trunk/loop branching. These small devices are insensitive to the operating wavelength and provide low optical loss with high directivity
Gould Fiber Optics has developed a GlasSolder process for making a glass to glass bond between optical fibers and silica substrate. The patented technique produces a uniform “solder” bead that affixes the fiber to the substrate to provide exceptional mechanical and environmental stability.
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’s single mode Fused wavelength Independend Couplers and Splitters are manufactured using Corning SMF 28 and available in various coupling ratios such as 50/50, 40/60, 30/70, 20/80, 10/90, 05/95 & 1/99 with dual operating wavelength bands 1310±40 & 1550±40, 1310±50 & 1520±40 and 1310±50 & 1530±50 with a band width range from 80 to 100nm. Other coupling ratio & wavelength options are available upon request. Available connector options are ST, FC, SC, LC, FC/APC & SC/APC
