This part of IEC 61746 provides procedures for calibrating multimode optical time domain reflectometers (OTDR). It covers OTDR measurement errors and uncertainties. The test of the laser(s) source modal condition is included as an optional measurement. This standard does not cover correction of the OTDR response.

EN IEC 61300-3-29 identifies two basic measurement methods for characterizing the spectral transfer functions of DWDM devices. The transfer functions are the functions of transmittance dependent of wavelengths. In this standard, optical attenuations are also used. The transfer functions can be used to produce measurements of insertion loss (IL), polarization dependent loss (PDL), isolation, centre wavelength, bandwidth (BW) and other optical performances.

EN IEC 61300-2-42 specifies a test to determine the influence of a side load applied to a cord assembled with a strain relief. The intention is to simulate a static load, due to a length of fibre cable, which would typically be experienced during service. Components should withstand side loads during optical transmission without degradation of the optical performance. Besides a boot, any feature that controls the bending radius of the fibre can be considered as strain relief.

This part of IEC 61753 contains the minimum test and measurement requirements and severity levels that a passive chromatic dispersion compensator (PCDC) using virtually imaged phased array (VIPA) must satisfy in order to be categorized as meeting the IEC standard, category C-controlled environments.

The requirements cover non-connectorized PCDCs used in single-channel transmission and wavelength division multiplexing (WDM) transmission in single-mode fibres(IEC 60793-2-50 B1/B2/B4).

This part of IEC 61300 details a procedure for determining the suitability of a fibre optic device to withstand the environmental condition of high humidity and high temperature which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of high humidity at constant temperature over a given period. Absorption of moisture may result in swelling that would destroy functional utility, cause loss of physical strength, and cause changes in other important mechanical properties. Degradation of optical properties may also occur. Although not necessarily intended as a simulated tropical test, this test can, nevertheless, be useful in determining moisture absorption of insulating or covering materials.

Communication today is digital and therefore sound, pictures, voice, data carried by networks are data expressed in terms of bit, bytes and their multiples (kilo (k), mega (M), giga (G), tera (T)). A bit (binary digit) is the smallest digital unit and has only two values: 0 or 1. A byte includes 8 bits and defines the size of a data file. Transmission capacity of networks and terminals is not expressed by using bytes, but using bit per second (Bit/s). When a data file is transferred in a network two supplementary bits are necessary. It means that 10 bits are required for 1 byte.

For other connectors (e.g. panel mounted connectors), the cable can be replaced by an adequate transmission-line (e.g. airline, stripline). In order to evaluate the effects of mechanical stresses on the connectors, a series of impacts is applied to the connectors while measuring the PIM.
