Based on Go!Foton’s patented technology, SELMUX™ series is introduced to cover all TFF-based components using an all-glass platform for improved performance, such as lower insertion loss and higher thermal stability, with a competitive cost structure. Because of its high thermal stability, SELMUX series can offer compliance to Outside Plant (OSP) requirement upon request.

Go!Foton’s DWDMs, are based on Go!Foton’s patent pending technology. This technology puts Go!Foton as one of  only a few companies with a unique process for tuning the center wavelength in the DWDM spectrum.  Based on NSG’s unique SELFOC technology, the process eliminates the severe manufacturing burdens placed on the thin film filter, thus simplifying center wavelength tolerances and reducing cost. Go!Foton’s SELMUX products are epoxy-free in the optical path and are in compliance with RoHS 6/6.
