So basically what happens is a single fiber runs from the OLT to a
passive splitter that you will find in some of the old Telstra poles
and pits around the place. A single fiber is used for TX and RX
using different wavelengths. <br></div></blockquote><div><br></div><div>Splitters are in roadside cabinets.
