Benet
is solution provides protection on the driver side
without impairing the VDSL2 signal.
Objective
VDSL2 uses frequencies of up to 30 MHz
to provide data rates exceeding 100 Mbit/s
simultaneously in both upstream and
downstream directions. is solution
protects these ports against lightning surge
and AC power contact threats.
