FOCI Technology

Fiber optic branching components are passive optical devices that include splitters, couplers and wavelength division multiplexers(WDMs). These components are used to split or combine different optical signals in terms of optical power or wavelength.


FOCI’s fiber pigtails/patchcords are assembled under extremely tight quality control procedures.These pigtails/patchcords feature ultra low insertion loss and return loss over a wide range of temperatures, wavelengths, and mechanical stresses.


Multiple distribution of optical signals is crucial as optical networks evolve and expand. A coupler (or splitter) is a passive device that connects 3 or more fiber ends, dividing the input signal between several outputs or combining several inputs into one output. They can significantly enhance your network system by dividing a signal according to a pre-determined ratio to drive multiple devices.


FOCI’s couplers are manufactured using innovative patented FBT(Fused Biconical Taper) design. These couplers feature ultra low insertion loss and backreflection over a wide range of temperatures, wavelengths, and under mechanical stresses. They can also be independent of wavelength to suit your needs.


FOCI’s couplers come with your choice of different packaging options and connector termination. The coupling ratio can be made with uniform or non-uniform coupling ratio.


To ensure our customers the best quality products, FOCI’s couplers are made to conform to Bellcore’s standard TA-NWT-001221 in terms of optical characteristics, mechanical testing and reliability.

Featuring with high optical performance and reliability, PLC splitter modules are widely applied in Fiber to the Home (FTTH) applications. FOCI offers the splitter modules with extremely low insertion loss; several configurations (like 1×4, 1×8, 1×16, 1×32, etc.) and packaging options are available to meet your requirement. FOCI not only provide you the high-quality splitter modules in compliance with rigorous Telcordia 1209 and 1221 reliability qualification requirement, but also volume production at lower cost.y.
