Description:

Go!Foton’s High Isolation Coupler is ideal for FTTx and B-PON / G-PON applications.  This coupler is based on Go!Foton’s new SELMUXTM patented technology which optimizes glass, epoxy and Filter-on-Lens (FOL) technologies to create integrated couplers with high isolation in a compact size.  Because of this revolutionary technology, Go!Foton’s High Isolation Couplers are one of  the smallest packaging sizes available in the market today.  All SELMUX products have eliminated soldering in the manufacturing process so they are completely lead free and comply with EU directives on Restriction of  Hazardous Substances or RoHS.
