DESCRIPTION:
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 NSG’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’sunique 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.
