Dual Band PB-OE
If two consecutive bands have to be attenuated, use a dual band PB-OE module. When more than two
add bands are to be attenuated, multiple VOA modules can be cascaded. The dual ban d PB- OE supports
bands AB, CD, EF, and GH. Use a dual band PB-OE module to equalize signals with at least two bands.
The diagram below show enlarged views of a dual band PB-OE module and single WB-VOA module for
