Some customers will know that long cable runs inside a building present real threats to Ethernet equipment. These long runs serve as antennas that can couple the energy from nearby lightning strikes into the system. Also, these long cables can develop a significant static charge if they are left unconnected. When plugged back into the equipment, this static charge can produce a very significant ESD event that can damage unprotected Ethernet ports. In North America, some parts of GR-1089 may apply. More and more uses for Ethernet are emerging in remote and often exposed areas such as in “Ethernet in the Final Mile” applications. In North America, this often means that GR-1089 inter-building requirements apply. Other highly exposed applications include Kiosks, campus networks and detached garages. Building security cameras mounted on poles in a parking lot presents challenges as well. Most of these exposed applications also have limited or no temperature control. In these exposed environments, Littelfuse has the protection solutions required for Ethernet connections.
