IEC 60793-2-30:2015(E9 is applicable to sub-categories A3a, A3b, A3c, A3d, A3e, A3f and A3g. These fibres are used or can be incorporated in different information transmission equipment, other applications employing similar light transmitting techniques as well as fibre optic cables. Three types of requirements apply to these fibres:<br /> - general requirements, as defined in IEC 60793-2;…

IEC 61300-3-35:2015 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61300-3-35:2015 describes methods for quantitatively assessing the end face quality of a polished fibre optic…

IEC 61300-3-35:2015 describes methods for quantitatively assessing the end face quality of a polished fibre optic connector or of a fibre optic transceiver using a fibre-stub type interface. Sub-surface cracks and fractures are not considered in this standard. In general, the methods described in this standard apply to 125 μ cladding fibres contained within a ferrule and intended for use with…

IEC 60143-1:2015 applies both to capacitor units and capacitor banks intended to be used connected in series with an a.c. transmission or distribution line or circuit forming part of an a.c. power system having a frequency of 15 Hz to 60 Hz. The primary focus of this standard is on transmission application. The series capacitor units and banks are usually intended for high-voltage power systems.…

IEC 62343-1-2:2015 contains the recommended minimum initialization test and measurement requirements and severities for optical tuneable chromatic dispersion compensators (TDC). This second edition cancels and replaces the first edition published in 2007. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition…

IEC 60793-2-30:2015 is applicable to sub-categories A3a, A3b, A3c, A3d, A3e, A3f and A3g. These fibres are used or can be incorporated in different information transmission equipment, other applications employing similar light transmitting techniques as well as fibre optic cables. Three types of requirements apply to these fibres: - general requirements, as defined in IEC 60793-2; - specific…

ISO 11151-1:2015 specifies requirements for laser components used in the ultraviolet, visible, and near infrared spectral ranges, from wavelengths 170 nm to 2 100 nm, and facilitates the supply of spare parts by specifying preferred dimensions and tolerances, thereby reducing the variety of types, by standardizing the specifications and removing barriers to trade, and by establishing an agreed…

ISO 11151-2:2015 specifies requirements for laser components used from near-infrared to mid-infrared, from wavelengths 2,1 µm to 15,0 µm, and facilitates the supply of spare parts by specifying preferred dimensions and tolerances, thereby reducing the variety of types, by standardizing the specifications and removing barriers to trade, and by establishing an agreed designation for item orders.…
