GENERIC REQUIREMENTS FOR GAS TUBE PROTECTOR UNITS (GTPUs)
出版:Telcordia Technologies

专家解读视频
Gas Tube Protector Units (GTPUs) are meant to stop unwanted surge voltages and currents on the outside plant from reaching terminal equipment used in telecommunications networks. This document details the criteria for GTPUs meant for use on paired conductors at Central Offices (COs) and customer stations, by carrier systems and on the vertical side of the main distributed frame in a CO building. Includes special electrical requirements needed to protect certain 5ESS line cards. The GTPU is capable of giving voltage only or combined voltage and current limiting features. Details GTPUs having backup devices that are air gaps or solid-state components such as thyristor diodes, avalanche diodes, or MOVs. Gives requirements that a GTPU shall have in order to help interference with the operation of telecommunications networks plus to help give surge-limiting that.
