ISO/IEC 11518-9:1999

This part of ISO/IEC 11518 specifies a physical level interface for transmitting digital data at 800 Mbit/s or 1 600 Mbit/s serially over fibre-optic cables across distances of up to 10 km. The signalling sequences and protocol used are compatible with HIPPI-PH, ISO/IEC 11518-1, which is limited to 25 m distances. HIPPI-Serial may be integrated as a host's native interface, or used as an external extender for HIPPI-PH ports Specifications are included for: ? the encoding and serialisation of the parallel data; ? the sequence of signals required for link reset; ? the timing and optical requirements of the serial signals; ? 32-bit (800 Mbit/s, 100 MByte/s) and 64-bit (1 600 Mbit/s, 200 MByte/s) operation; ? simplex and dual simplex operation.
