IEC 62300-2004 pdf – Consumer audio/video equipment digital interface with plastic optical fibre.
1 Scope This International Standard specifies the principal electrical and optical parameters for a consumer audio/video equipment digital interface that uses plastic optical fibre (POF). NOTE A description of the principal features of such an interface is given in Annex C. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60050-731, International Electrotechnical Vocabulary (IEV) – Chapter 731: Optical fibre communication IEC 60793-2-40, Optical fibres – Part 2-40: Product specifications – Sectional specification for category A4 multimode fibres IEC 60825-1, Safety of laser products – Part 1: Equipment classification, requirements and user’s guide IEC 60825-2, Safety of laser products – Part 2: Safety of optical fibre communication systems IEC 61754-21, Fibre optic connector interfaces – Part 21: Type SMI connector family for plastic optical fibre 1 3 Terms, definitions and abbreviations 3.1 Terms and definitions For the purposes of this document, the terms and definitions contained in IEC 60050-731 apply. 3.2 Abbreviations BER Bit error rate D-VCR Digital video cassette recorder E/O Electrical to optical HDTV High definition television O/E Optical to electrical PECL Positive shifted emitter coupled logic PMD Physical media dependent POF Plastic optical fibre RMS Root mean square
4 System consideration 4.1 Area of application This digital interface covers audio and/or video and accompanied data systems for consumer audio/video equipment and multimedia systems in bi-direction, mainly used for audio equipment, TV-set, D-VCR, etc. 4.2 Operating environment The environmental conditions for the digital interface are mainly defined in other standards for the individual units. Where no range is given, the interface shall operate at least within the temperature range 0 °C to 50 °C and in a relative humidity range of 25 % to 75 %. 5 Configuration of digital interface and characteristics to be specified 5.1 Configuration of digital interface The basic configuration of this digital interface is shown in Figure 1. The reference points 1 and 4 apply to the electrical input and output of the electro-optical and opto-electrical converter respectively. The optical matching values specified in this standard apply at the reference points 2 and 3. The overall characteristics of a POF are specified in Annex A for a wide-band POF and in Annex B for the optical connectors. NOTE Some applications based on this digital interface are illustrated in Annex C.
