Based on Go!Foton’s patented technology, SELMUXTM 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  it’s high thermal stability, SELMUX series can offer compliance to Outside Plant (OSP) requirement upon request.

Go!Foton’s Coarse Wavelength Division Multiplexing (CWDM) OADMs are based on its unique TFF SELMUX technology that provides a high quality CWDM device with high channel isolation, low polarization dependent loss, flat and wide passband, and stable environmental performance.  Go!Foton’s TFF SELMUX products are epoxy-free in the optical path and are in compliance with RoHS 6/6.
