Referring to the DELNI Owner's Manual, you will find a table on page 35
which describes the impact that the DELNI has on cable lengths in various
configurations.  Basically, when using a DELNI to provide multiple
connections from a single tranceiver, the DELNI represents 15 meters of
tranceiver cable.  Thus the maximum distance from tranceiver to device is
reduced from 50 meters to 35 meters.

Similar boxes provided by other manufacturers have the same type of
restriction on the length of the tranceiver cable.  It is critical that you
find this specification for any unit you plan to use, and keep it in mind
while designing your network.
