Note:
In light of item 5 in Annex of 2002/95/EC, “Pb in the glass of cathode ray tubes, electronic components and
fluorescent tubes.” and item 13 in Annex of 2005/747/EC, “Lead and cadmium in optical and filter glass.”,
the two exemptions are being concerned for Source Photonics transceivers, because Source Photonics
transceivers use glass, which may contain Pb, for components such as lenses, windows, isolators, and
other electronic components.
