Categories: , Tags: , , , ,

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.


Telcordia GR-1221 Compliant
Low Insertion Loss
 RoHS Compliant (Lead Free)
Epoxy-Free Optical Path
Low Polarization Dependent Loss
Flat and Wide Passband
Exceptionally Stable and Reliable
