1.1 General<\/b><\/p>\n

This part of IEC 62661 gives guidelines for an optical backplane using optical fibre boards and multi-core right angle optical connectors with low bending loss multimode fibres (hereafter called low-loss RAO) to connect daughter boards to the optical backplane.<\/p>\n

\n

NOTE Low bending multimode fibres are currently under study.<\/p>\n<\/blockquote>\n

1.2 Product definition<\/b><\/p>\n

The structure of an optical backplane specified in this specification is as follows<\/p>\n

    \n
  1. \n

    The optical backplane has the structure to fit to a sub-rack specified in IEC 60297-3-101 with a height of more than 3U (44,45 mm \u00d7 3).<\/p>\n<\/li>\n

  2. \n

    One optical backplane occupies a space of 100 mm (height) and 420 mm (width) in the optical backplane stated in item a).<\/p>\n<\/li>\n

  3. \n

    A multiple number of optical backplanes may be installed to a sub-rack specified in IEC 60297-3-101 if multiple spaces specified in item b) are available, that is, a height of 44,45 mm \u00d7 N (N\u22655).<\/p>\n<\/li>\n

  4. \n

    The backplane installs maximum of 14 front boards (daughter boards) with a pitch of 6HP (30,48 mm).<\/p>\n<\/li>\n

  5. \n

    New Type RAO connectors specified in Annex B are used in the optical backplane.<\/p>\n<\/li>\n

  6. \n

    Multimode optical fibres are used for optical wiring in the optical backplane. More specifically, the optical backplane is made of an optical fibre board specified in IEC 62496-3-1 using low bending loss optical fibres.<\/p>\n<\/li>\n<\/ol>\n

    1.3 Connection arrangement<\/b><\/p>\n

    Connection arrangement for the optical backplane is as follows:<\/p>\n

      \n
    1. \n

      The construction of optical connection specified in this document consists of using the compact right-angled optical board connectors specified in Annex B which are mounted on an optical backplane housed in a sub-rack specified in IEC 60297-3-101.<\/p>\n<\/li>\n

    2. \n

      The slots are assigned the following numerical designations in this specification: the slot on the left end is designated slot number 1, and the slot on the right end is designated slot number 14. The daughter board located at slot 7 or slot 8 is defined as daughter board B, while daughter boards located on any of the other slots are defined as daughter board A. This document specifies an optical dual star connection between daughter board A and daughter board B.<\/p>\n<\/li>\n<\/ol>\n

      1.4 Classification of connections<\/b><\/p>\n

      Connections in this specification are classified as shown in Table 1.<\/p>\n

      Table 1 \u2013 Classification of ferrules<\/b><\/p>\n

      The 16 core MT ferrule and the 24 core MT ferrule used on DS 384 optical backplane are 125 \u00b5m pitch high-density MT ferrules defined by Figure B.5.<\/p>\n

      1.5 Operating environment<\/b><\/p>\n

      The operating environment is specified in Table A.1 of IEC 62496-3:2011, Category C (temperature range of \u201310 \u00b0C to +60 \u00b0C).<\/p>\n
