Headquartered and i
5、ncorporated 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 these Committees is open to all
6、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 the rules given in its Standards Operations Manual. SMPTE ST 2091-1 was prepared by Technology Commi

The holder of such patents is prepared to grant a license to its essential patent claims to an unrestricted number of applicants on a worldw
8、ide, non-discriminatory basis and on reasonable terms and conditions (RAND). Introduction This section is entirely informative and does not form an integral part of this Engineering Document. This standard describes an optical connector system based on type LC or type MPO connectors which is targeti
9、ng two areas of application, fixed installations and mobile use in the field. Therefore two performance classes are introduced. Applications with multiple mating cycles in a rather harsh environment require ruggedized connectivity solutions. The connectors specified in this document provide adequate
10、 features to cope with relevant requirements for harsh environments. SMPTE ST 2091-1:2017 Page 3 of 37 pages 1 Scope This document specifies ruggedized fiber-optic connectors based on standardized fiber-optic connectors, intended for use in HDTV and UHDTV broadcasting and video equipment where robus
11、t and reliable solutions are required. The connectors are intended to be used for optical fiber systems such as defined in SMPTE ST 297-1, SMPTE ST 435-3 and SMPTE ST 2036-3. This standard defines dimensional requirements related to reference planes of the underlying connector interfaces as standard
12、ized in IEC 61754-7 and IEC 61754-20. Furthermore structural and performance requirements are included considering optical and mechanical specifications. 2 Conformance Notation Normative text is text that describes elements of the design that are indispensable or contains the conformance language ke
13、ywords: “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 affecting interoperability. Informative text does not contain any conformance keywords. All text in this document is
14、, 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“ indicate requirements strictly to be followed in order to conform to the document and from which no deviation is pe
15、rmitted. The keywords, “should“ and “should not“ indicate that, among several possibilities, one is recommended as particularly suitable, without mentioning or excluding others; or that a certain course of action is preferred but not necessarily required; or that (in the negative form) a certain pos
16、sibility 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 “reserved” indicates a provision that is not defined at this time, shall not be used, and may be defined in the futur
17、e. 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 is one that includes all mandatory provisions (“shall“) and, if implemented, all recommended provisions (“should“)
18、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 of the types of normative information in this document shall be as follows: Normative prose shall be the authoritativ
19、e definition; Tables shall be next; followed by formal languages; then figures; and then any other language forms. 3 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. At the time of publication, the editions

All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent edition of the standards indicated below.

30、s and Acronyms 4.1 Angled Physical Contact (APC) The fiber endfaces are polished with an angle of 5 to 15 relative to the axis vertical to minimize possible back reflections. 4.2 Connector Ruggedized free component of connector system, assembled to multi-fiber patch cords and jacketed cables. 4.3 Mu
31、ltimode (MM) Fiber Optical fiber with a larger core diameter in which the waves of multiple modes can propagate at the wavelength of interest. Due to its lower bandwidth-distance product this type of fiber is suitable for wideband transmission over short distances only. However it simplifies connect
32、ions and allows the use of lower-cost light sources in premises applications. 4.4 Physical Contact (PC) The fiber endfaces are polished with a convex rounded surface to make physical contact in the connector near the fiber core. 4.5 Receptacle Ruggedized fixed component of connector system, acting a
33、s adapter installed in rack- or wall-mounted patch panels to intermate connector terminated fiber cables, or on terminal equipment to provide the interface between active optical devices and cabling circuits 4.6 Single Mode (SM) Fiber Optical fiber with a small core diameter in which the wave of onl
34、y one mode can propagate at the wavelength of interest. This type of fiber is particularly suitable for wideband transmission over large distances. 5 Connector System Three different non-compatible connector systems are being specified: - DUO: system based on the use of two parallel LC terminated fi
35、bers, in terms of a LC duplex connector. - QUAD: system based on the use of four parallel LC like terminated fibers, in terms of two mirrored LC duplex like connectors. - MPO: system based on the use of one MPO like coupler terminating up to 12 fibers in a single row or 24 fibers in two rows. 5.1 St
36、ructural Requirements The interconnection system shall consist of a connector to connector arrangement, i.e. connectors shall be installed at both ends of the cable, while the receptacle acts as a feed-through adapter. Note: In terminal equipment an E/O transmitter, receiver or transceiver, commonly
37、 mounted on a printed circuit board, can be connected to the panel mount receptacle by means of a patch or installation cable with connectors of type LC or type MPO respectively. SMPTE ST 2091-1:2017 Page 6 of 37 pages Figure 1 Elements of the interconnection system 5.2 Types and Classification In t
38、his document the various types are identified as follows: - DUO connector: shall house two type LC connectors with PC polished fiber ends in a duplex configuration. - DUO receptacle: shall house one type LC duplex adapter. - QUAD connector: shall house four 1.25 mm ferrules based on type LC connecto
39、rs with PC polished fiber ends in a double duplex configuration. Note: In a type LC compatible configuration double duplex would mean one duplex with keys up and one duplex with keys down. Keys are not relevant in this type of connector. - QUAD receptacle: shall house two duplex adapters based on ty
40、pe LC, arranged top with keys up and bottom with keys down. Note: Keys are not relevant with regard to mating interface. - MPO connector: shall house a female MPO ferrule with guide holes to accept the alignment pins of the mating connector. - MPO receptacle: shall house an MPO adapter with a key-up
41、/key-down configuration as shown in Figure 17. Note: Key-up/key-down is also referred to as type A configuration enabling connection of the fibers in accordance to polarity Method A as defined in TIA-568-C.0. The use of a key-up/key-down adapter results from the possible use of SM fibers with APC po
42、lished endfaces. Connectors are classified into two performance classes according to the type of use: - MOBILE: Connector for mobile applications and harsh environment, including enhanced means for cable protection. - FIXED INSTALLATION: Connector for fixed installations and less demanding environme
43、nts. Corresponding differing requirements are defined in Section 7.2.
