Protective Telecommunications Enclosure Systems and Methods

A method of producing a high-altitude electromagnetic pulse (“HEMP”) protected enclosure for holding an electronic device, comprising:

• building a test HEMP protected enclosure of an enclosure design;
• performing an acceptance testing procedure on the test HEMP protected enclosure;
• determining whether the test HEMP protected enclosure meets a HEMP protection level that includes a shielding effectiveness of at least 80 dB attenuation at 1 GHz, with a residual peak current of less than 10 A, a rate of rise less than 1.0e+0.7, and a root action of less than 1.6e−01 in response to a signal incident on the HEMP protected enclosure, the signal simulated by an input waveform into a short circuit having a risetime of less than 20 ns and a full width half maximum (“FWHM”) of between 500 and 550 ns;
• and
• producing a plurality of HEMP protected enclosures of the enclosure design if the test HEMP protected enclosure meets the HEMP protection level;
• wherein the test HEMP protected enclosure comprises a cabinet having an interior space to house the electronic device, the cabinet having cabinet width dimension of about 26 inches and a cabinet depth dimension of about 38 inches, a cabinet width dimension of about 65 inches and a cabinet depth dimension of about 30 inches, or a cabinet width dimension of about 26 inches and a cabinet depth dimension of about 20¼ inches.
