6、nization. Headquartered and incorporated in the United States of America, SMPTE has members in over 80 countries on six continents. SMPTEs Engineering Documents, including Standards, Recommended Practices, and Engineering Guidelines, are prepared by SMPTEs Technology Committees. Participation in the

7、se Committees is open to all with a bona fide interest in their work. SMPTE cooperates closely with other standards-developing organizations, including ISO, IEC and ITU. SMPTE Engineering Documents are drafted in accordance with its Standards Operations Manual. SMPTE ST 297 was prepared by Technolog

8、y Committee 32NF. Intellectual Property At the time of publication no notice had been received by SMPTE claiming patent rights essential to the implementation of this Standard. Attention is drawn, however, to the possibility that some of the elements of this document may be the subject of patent rig

9、hts. SMPTE shall not be held responsible for identifying any or all such patent rights. SMPTE ST 297:2015 Page 3 of 26 pages 1 Scope This standard defines an optical fiber system for transmitting bit-serial digital signals. It is intended for transmitting SMPTE ST 259 signals (143 through 360 Mb/s),

10、 SMPTE ST 344 signals (540Mb/s), SMPTE ST 292-1/2 signals (1.485 Gb/s and 1.485/1.001 Gb/s), SMPTE ST 424 signals (2.970 Gb/s and 2.970/1.001 Gb/s), SMPTE ST 2081-1 signals (5.940 Gb/s and 5.940/1.001 Gb/s) and SMPTE ST 2082-1 signals (11.88 Gb/s and 11.88/1.001 Gb/s). 2 Conformance Notation Normati

11、ve text is text that describes elements of the design that are indispensable or contains the conformance language keywords: “shall“, “should“, or “may“. Informative text is text that is potentially helpful to the user, but not indispensable, and can be removed, changed, or added editorially without

12、affecting interoperability. Informative text does not contain any conformance keywords. All text in this document is, by default, normative, except: the Introduction, any section explicitly labeled as “Informative“ or individual paragraphs that start with “Note:” The keywords “shall“ and “shall not“

13、 indicate requirements strictly to be followed in order to conform to the document and from which no deviation is permitted. The keywords, “should“ and “should not“ indicate that, among several possibilities, one is recommended as particularly suitable, without mentioning or excluding others; or tha

14、t a certain course of action is preferred but not necessarily required; or that (in the negative form) a certain possibility or course of action is deprecated but not prohibited. The keywords “may“ and “need not“ indicate courses of action permissible within the limits of the document. The keyword “

15、reserved” indicates a provision that is not defined at this time, shall not be used, and may be defined in the future. The keyword “forbidden” indicates “reserved” and in addition indicates that the provision will never be defined in the future. A conformant implementation according to this document

16、 is one that includes all mandatory provisions (“shall“) and, if implemented, all recommended provisions (“should“) as described. A conformant implementation need not implement optional provisions (“may“) and need not implement them as described. Unless otherwise specified, the order of precedence o

17、f the types of normative information in this document shall be as follows: Normative prose shall be the authoritative definition; Tables shall be next; followed by formal languages; then figures; and then any other language forms. 3 Normative References Note: All references in this document to other

18、 SMPTE documents use the current numbering style (e.g. SMPTE ST 259:2008) although, during a transitional phase, the document as published (printed or PDF) may bear an older designation (such as SMPTE 259M-2008). Documents with the same root number (e.g. 259) and publication year (e.g. 2008) are fun

19、ctionally identical. The following standards contain provisions that, through reference in this text, constitute provisions of this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this standard are enc

20、ouraged to investigate the possibility of applying the most recent edition of the standards indicated below.

26、IEC 61754-20-1. Other application-specific connector types such as SC, ST, FC, MU, etc. may optionally be specified. The Tx / Rx unit or its product documentation should indicate the connector type. Furthermore, the product documentation should include detailed mechanical and optical specifications

27、for the specified connector. 4.1.2 The preferred Tx and Rx unit optical domain connector polish shall be PC. Other application-specific connector polishes such as SPC, UPC and APC may optionally be specified, provided the polish is clearly labeled as described in Sections 4.3 and 4.5 below. The Tx /

28、 Rx unit product documentation shall include detailed specifications for the required optical connector polish. Note: While angle-polish connectors (i.e. APC) and flat-polish connectors (i.e. PC, SPC, and UPC) of the same type (e.g. LC) can be mechanically mated, they are not optically compatible. S

29、ystem designers and system installers are therefore advised to ensure compatibility of cable, connector type and polish throughout the installation.
