ISO IEC 9314-4:1999 pdf download – lnformation technology – Fibre distributed data interface (FDDI)- Part 4: Single-mode fibre physical layermedium dependent (SMF-PMD).
This part of ISOIEC 9314 specifies the Single-mode fibre Physical Layer Medium Dependent (SMF-PMD) requirements for the Fibre Distributed Data Interface (FDDI).
FDDI provides a high bandwidth (100 megabits per second) general purpose interconnection among computers and peripheral equipment using a fibre optic waveguide as the transmission medium. The FDDI may be configured to support a sustained transfer rate of approximately 80 megabits (10 megabytes) per second. The FDDI may not meet the response time requirements of all unbuffered high speed devices. The FOOl establishes the connection among many stations distributed over distances of several kilometers in extent. Default values for FDDI were calculated on the basis of 1000 physical connections and a total fibre path length of 200 kilometers (see the MAC Standard — ISOiIEC 9314-2 or ISOJIEC 9314-8).
The FOOl consists of:
1) The Physical Layer Medium Dependent (PMD) is specified in four alternative standards:
a) ISO/lEG 93 14-3 (FDDI PMD) corresponding to multimode fibre (MMF) wtiich actually means FDDI MMF-PMD.
b)This standard ISOiIEC 9314-4 (SMF.PMD) which contains the requirements for single- mode fibre (SMF) physical connections between stations.
C) ISO/IEC 9314-9 (FDDI LCF-PMD), an alternative lower cost multimode fibre (LCF) for shorter distances.
d) ISO/lEG 93 14-10 (FDDI TP-PMD), a copper twisted pair (TP) alternative,
An FDDI ring can be made up of all these alternatives. (For some restrictions see 6.4). The PMD provides all services necessary to transport a suitably coded digital bit stream from station to station. The SMF-PMD specifies the point of interconnection requirements for FDDI stations and cable plants at both sides of the Media Interface Connector (MIC) for conforming stations utilizing single-mode fibre.
SMF-PMD includes the following:
i) The optical power budgets for Iwo (2) categories of Active Output and Active Input Interfaces using single-mode fibe optic cables and optical bypass switches
ii) The MIC Receptacle mechanical mating requirements including the keying features
ill) The slngle.mode fibre optic cable requirements
iv) The services provided by PMD to PHY and SMT
2) A Physical Layer Protocol (PHY). which provides connection between multimode or single- mode PMD and the Data Link Layer (DLI). PHY establishes clock synchronization with the upstream code-bit data stream and decodes this incoming code-bit stream into an equivalent symbol stream for use by the higher layers. PHY provides encoding and decoding between data and control indicator symbols and code-bits, medium conditioning and initializing, the synchronization of incoming and outgoing code-bit clocks, and the delineation of octet boundaries as required for the transmission of information to or from higher layers. Information to be transmitted on the interface medium is encoded by the PHY into a grouped transmission code.
3) A Data Link Layer (DLI), which controls the accessing of the medium and the generation and verification of frame check sequences to assure the proper delivery of valid data to the higher layers. DLL also concerns itself with the generation and recognition of device addresses and the peer-to-peer associations within the FDDI network. For purpose of the PHY, references to DLL are made in terms of the Media Access Control (MAC) entity, which is the lowest sublayer of DLL.
4) A Station Management (SMT), which provides the control necessary at the station level to manage the processes underway in the various FODI layers such that a station may work cooperatively on a ring. SMT provides services such as control of configuration management, fault isolation and recovery, and scheduling procedures.
This part of ISO/IEC 9314 Is a supporting document to ISO/IEC 9314-1 which should be read In conjunction with it.
The SMT document ISOiIEC 93 14-6 should be consulted for information pertaining to supported FDDI station and network configurations.
The set of FDDI standards specifies the interfaces, functions and operations necessary to insure interoperability between conforming FODI implementations. This part of ISO?IEC 9314 is a functional description. Conforming implementations may employ any design technique which does not violate interoperability.
