Data line surge suppressors for comprehensive
network and PC system protection
|
Data line surges make up an overwhelming majority of all surge
induced damages where the equipment was thought to be already
protected but had a “back door” such as a modem line
unprotected. Network interface cards, in particular, can be destroyed
by relatively mild spikes.
According to Ethernet standards (IEEE 802.3), non-AC network
electrical hazards include: Direct contact between components
and power or lightning circuits, static charge buildup on cables
and component, high-energy transients coupled onto the local
cabling system (those induced by other cables which are installed
in the general proximity of network cables or lightning within
a mile radius) and potential differences (even from building
to building, between safety grounds to which components are
connected.)
