The American company Lightel was founded in 1999 and has its headquarters in Seattle, Washington. Lightel produces coupler workstations for the manufacture of fibre-optic components using the fused biconical taper (FBT) method.

With hundreds of coupler workstations installed worldwide, Lightel sets the benchmark in almost all coupler manufacturing companies. In addition to standard fibres with a diametre of 125 µm, thicker fibres and polarisation-maintaining fibres can also be processed.  

Lightel uses its own expertise in the area of coupler workstations for the production of a variety of fused coupler-based components. This includes fibre-optic splitters for multi-mode, single-mode, and PM fibres, wavelength-division multiplexers (WDMs), and high-power combiners.

This product range is supplemented by filter-based optical components, such as CWDM and DWDM filters, optical isolators, circulators, optical attenuators, and polarisation beam splitters and combiners.
