Multimode (MM) fused bidirectional fiber optic star couplers & Optical Splitters are capable of operating over a broad wavelength range (i.e. 850nm and 1300nm). Multimode couplers are typically used for short distance data transmission. Gould multimode fused couplers can be used within fiber optic instrumentation, sensor systems and local area networks. Additionally, Gould multimode and large core couplers are manufactured and tested under fully-filled launch conditions. An underfilled launch may alter coupling ratio.
Our couplers 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 Multimode (MM) 1X2 & 2X2 Fiber Optic Couplers & Optical Signal Splitters can be manufactured using different fiber types such as 50/125um, 62.5/125um, 100/140um, and OFS 100/140/250um 0.2NA Graded Index. Gould’s Large Core HCS (Hard-Clad Silica) 1X2 & 2X2 Fiber Optic Couplers & Optical Signal Splitters are manufactured using different fiber types such as 200/230/500um .37NA SI MM HCS, 200/230/500um .48NA SI MM HCS, and 300/330/650um .37NA SI MM HCS.
