COPPER SFP CONNECTIVITY
Hydra2 network connections can
be made via copper SFP modules.
Copper connections require shielded
F/UTP Category 5e or Category 6
cables with shielded RJ45 mating
connectors. Core connections should
only be made using optical/fibre SFP
modules.
It is important to note that Copper
SFPs must support LOS (Loss of
Signal) detection - these are not
standard for copper SFPs, but are
commonly available, Calrec supplied
copper SFPs do support LOS.
