38、x C (informative) Interface applications C.1 Principal features The digital interface specified in this standard uses wide-band POF that includes both the multi-layer type and the graded index type. These features provide an optical signal speed of up to 500 Mbit/s and a single hop distance of up to
39、 50 m. By using this interface, the high- speed digital signals which include audio/video signal and multimedia data are transmitted simultaneously. It is further possible to realize consumer audio/video equipment platform and/or multimedia system with low cost and high performance. This digital int
40、erface has five features that are important in consumer audio/video equipment. It is possible to transmit the high speed digital signal without introducing any electromagnetic interference. This interface overcomes the transmission limitation of an electrical interface. The optical connector of the
41、interface is so small that it is convenient to mount in consumer audio/video equipment, such as D-VCR, STB, HDTV, and so on. Wide-band POF and an optical transceiver of the interface operate up to 500 Mbit/s and the single hop distance is up to 50 m. This feature applies to such as IEEE P1394b/S400.
42、 This interface has upward compatibility for an industrial optical interface based on POF. Typical applications are discussed in Clauses C.2 and C.3. C.2 Connection between D-VCR and TV The basic connection between D-VCR and TV using the interface is shown in Figure C.1. In this application, the req
43、uest control signal is transmitted from TV to D-VCR and the digital video stream is transmitted from D-VCR to TV through POF. 4 POF Tx/Rx (E/O) (O/E) Rx/Tx (O/E) (E/O) D-VCR TV 3 2 1 IEC 1470/04Figure C.1 Connection between D-VCR and TV using the interface Page10 EN62300:2005C.3 Connection between a
44、 CD player and an audio amplifier The basic connection between CD player and audio amplifier using the interface is shown in Figure C.2. In this application, the request control signal is transmitted from an audio amplifier to a CD player and the digital audio stream is transmitted from the CD playe
45、r to the audio amplifier through POF. After that, the audio signal is regenerated by a speaker. 4 POF Tx/Rx (E/O) (O/E) Rx/Tx (O/E) (E/O) CD player Audio amplifier 3 2 1 IEC 1471/04Figure C.2 Connection between a CD player and an audio amplifier using the interface Page11 EN62300:2005 Annex ZA (norm
