Overview:
It is critical for today’s networks to maintain
maximum reliability and uptime. Overvoltage surges caused by indirect lightning,
power line transients, and ESD can wreak havoc on a network that is not properly
protected. Short circuit and overload conditions can cause safety issues for the
equipment and the users. With some simple design considerations for protecting
network and telecommunications ports, the equipment makers can ensure that
application standards are met and equipment is protected against these types of
faults. Proper fuse and PTC selection as well as selecting the optimal TVS Array
will be discussed. High speed networks now require TVS diode arrays with
ultra-low capacitance, high surge capability, and very fast clamping speed. Low
dynamic resistance of these TVS diode arrays become more critical as PHY
chipsets are inherently very weak to surge and ESD events.

What
attendees will learn:

  • Identify pertinent standards and/or regulatory requirements for network
    protection
