What is PD IEC/TS 62661-2-1 - Optical backplanes about?
PD IEC/TS 62661 is a series on optical backplanes. Optical backplanes are a group of electrical connectors in parallel with each other so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus. PD IEC/TS 62661-2-1 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.
Who is PD IEC/TS 62661-2-1 - Optical backplanes for?
PD IEC/TS 62661-2-1 on optical backplanes is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use PD IEC/TS 62661-2-1 - Optical backplanes?
The optical circuit board are in which optical connectors are mounted in parallel and the connectors are mutually connected by optical waveguides, which are physical lines of optical signals such as but not limited to, an optical fibre, planar polymer waveguide, planar glass waveguide, and other optical circuit boards, which are called daughter boards, are assembled on the board vertically to construct a book-shelf like structure.
PD IEC/TS 62661-2-1 specifies the structure of an optical backplane which are the structure to fit a sub-rack specified in IEC 60297-3-101 with a height of more than 3U (44,45 mm × 3), one optical backplane occupies a space of 100 mm (height) and 420 mm (width) in the optical backplane stated in item a). Multiple numbers 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 × N (N_5). The backplane installs a maximum of 14 front boards (daughter boards) with a pitch of 6HP (30,48 mm). New Type RAO connectors specified in Annex B are used in the optical backplane. Multimode optical fibres are used for optical wiring in the optical backplane. More specifically, the optical backplane is made of an optical fibreboard specified in IEC 62496-3-1 using low bending loss optical fibres. Using PD IEC/TS 62661-2-1 you can specify 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).
