Filter Tap Coupler
DiCon's Filter Tap Coupler is constructed using DiCon
Cylindrical Filter WDM packaging technology. The component
uses a thin film filter mounted between a pair of GRIN lens
collimators. DiCon's Filter Tap Coupler is housed in a compact,
environmentally stable package that offers superior resistance
to humidity and temperature and is suitable for mounting
within a line interface or amplifier gain module.
