DESCRIPTION:
Based on Go!Foton’s patented technology, SELMUXTM series is introduced to cover all TFFbasedcomponents using an allglass platform for improved performance, such as lower insertionloss 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 Coarse Wavelength Division Multiplexing (CWDM) Mux and DeMux Modules are based on itsunique 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 inthe optical path and are in compliance with RoHS 6/6.
