TIA-455-200 - FOTP-200 Insertion Loss of Connectorized Polarization-Maintaining Fiber or Polarizing Fiber Pigtailed Devices and Cable Assemblies
September 19, 2001 - TIA

Intent This Standard specifies a procedure for the measurement of the insertion loss of a fiber optic interconnection on single mode, highly linearly birefringent optical fiber, i.e. either polarization-maintaining fiber (PMF) or polarizing fiber (PZF). The connector can be mounted on the PMF/PZF...

ATIS 0600005 - Acoustic Measurement
December 1, 2017 - ATIS

Executive Summary This standard identifies sound power as the preferred method of measuring the emission of acoustic noise from telecommunications equipment. The main focus is to use sound power to gain repeatability and accuracy over sound pressure methods. This standard will also provide the...

ANSI/ASA S1.26 - American National Standard Methods for Calculation of the Absorption of Sound by the Atmosphere
January 1, 2014 - ASA

This Standard specifies an analytical method to calculate the attenuation of sound as a result of atmospheric absorption for a variety of meteorological conditions when the sound from any moderateamplitude source propagates through the atmosphere. The calculation method of the Standard applies for...
