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.
