The ChannelMap
function provides an intuitive map of
the cabling under test. You can use this function to
quickly survey connections and the lengths of fibers in a
channel.
This function is optimized for resolving connections as
close as 1 m apart on multimode fiber and 2 m apart on
singlemode fiber. Reflective events that do not appear to
be connectors are not shown on the map. Loss events are
also not shown.
Since the ChannelMap function identifies only
reflections, it is not appropriate for finding
fusion splices or angled physical contact (APC)
connectors.
