Fiber splitters are comprised of three fibers – two fiber legs on one side that overlap inside a junction with a third fiber at the common end. The fiber type used in each leg is typically the same, but can also be custom configured to have different fiber core diameters or wavelength ranges.

Fiber splitters are good for mixing light from two different locations and delivering it through a single fiber to a spectrometer or sample.  This ability can be used to combine illumination from two different light sources, or to mix light collected from two different sampling points before delivery to a spectrometer.

These assemblies have lower transmission than bifurcated fibers due to the inefficient geometrical overlap between the fiber cores at their junction point.  Split fiber assemblies for small diameter core fibers are not recommended for this reason, as their thicker cladding diameter results in minimal geometric overlap.

lab-grade splitterOff-the-shelf lab-grade fiber splitters are intended for light use, with PVDF zip tube jacketing and basic hex SMA connectors. They offer high quality at an affordable price. Premium-grade bifurcated fibers can be built on a custom basis to meet more demanding needs, as can custom configurations.
