Go!Foton’s B-PON/FTTP Coupler is ideal for FTTx and B-PON / G-PON applications. This coupler is based on SELMUXTM patented technology which optimizes glass, epoxy and Filter-on-Lens (FOL) technologies to create a high quality 3-port EWDM device with low PDL, low insertion loss and stable environmental performance. Go!Foton’s SELMUX series are all epoxy-free in the optical path and are completely lead free that comply with RoHS 6/6.
