  1. A 10Gbps SMPTE 292M compatible optical interface July.13.2005 Sony Corporation

  2. Basic Concept for the interface • Shares same structure as 1.5Gb/s SDI. • A low delay real-time interface with timing reference signals up to 10Gb/s. • Transmission length up to 2 km. • Adopts existing transmission module. • Uses “XFP” designed for 10Gb-E or Fibre channel • Primary payloads. • 4k2k D-Cinema image • 1080/50P and 1080/60P HDTV image • Up to 5 channels of 1.5Gb/s SDI

  3. Real-Time Synchronous Interface • Clock Frequency • Fck = 74.25 MHz144 = 10.692GHz • Complies with S274M digital representation. • Locked to 74.25MHz Image Sampling clock. • 7.2 times Fck with S292M ( 1.5Gb/s SDI ) • I/O stream for the interface is 1.5Gb/s SDI. • SMPTE 292M or SMPTE 372M can be embedded. • 1.5Gb/s Timing Reference Signals are completely maintained through 10Gb/s SDI.

  4. Description Specification Dimension 78188mm Power Consumption 2 W(Transceiver) LASER wavelength 1,310 nm Transmission module for 10Gbps • XFP MSA v3.1 XFP is used for • OC192/STM-64 9.95 Gb/s • 10 Gigabit FC 10.5 Gb/s • ITU-T G.709 10.7 Gb/s • IEEE802.3ae 10.3 Gb/s (10 Gigabit Ethernet ) And… • 10Gb/s-SDI 10.69Gb/s

  5. Trend of XFP market price  This forecast is derived from one of Japanese manufacturer.

  6. Applications beyond 1.5Gb/s • Applicable image formats

  12. Experimental Hardware  Every component used in the hardware is a commercial product.

  13. Transmission performance • 24h transmission test with 2km fiber was completed with no error.

  14. Summary • Practical optical interface for 10 Gb/s image transmission was confirmed by experiments. • All Formats defined in S274M ( e.g. 4:4:4, 1080/60P ) and 4k2k D-Cinema image can be transmitted. • Error free transmission over 2km has been confirmed. • No exclusive component is needed for the interface. • Estimated hardware cost would be around twice as much as current 1.5Gb/s SDI. Is the interface worth standardizing?
