High Isolation EWDM 1x2 for PON
PASSIVE OPTICSFEATURES:ITU Recommended Wavelength Grid
High Isolation
Telcordia GR-1221 Compliant
Low Polarization Dependent Loss
Low Insertion Loss
Flat and Wide Passband
Epoxy- Free Optical Path
Exceptionally Stable and Reliable
RoHS Compliant (Lead Free)APPLICATIONS:
B-PON/ G-PON/ E-PON/ Ge-PON
FTTx

DESCRIPTION:
Go!Foton’s High Isolation EWDM 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 a High Isolation 3-port EWDM device with low PDL, low insertion loss and stableenvironmental performance in a compact size. Because of this revolutionary technology, Go!Foton’s High
Isolation EWDM are one of the smallest packaging sizes available in the market today. All SELMUX products haveeliminated soldering in the manufacturing process so they are completely lead-free and comply with EU
directives on Restriction of Hazardous Substances or RoHS.
