5、OPS SMPTE REGISTERED DISCLOSURE DOCUMENT RDD 16-2008 Page 2 of 14 pages Overview This Registered Disclosure Document (RDD) describes a connector intended for use connecting a broadcast camera to its camera control unit (CCU). This connector has been used in heavy-duty environments at broadcasting fa

6、cilities in Japan, other Asian countries and Central America. However, this connector has not been used in the United States of America yet. When this connector starts to be used in the United States of America in the future, the proponent will consider submitting it to SMPTE for formal standardizat

It defines hybri

9、d connectors, which contain a combination of electrical contacts and fiber-optic contacts for single-mode fibers. This document also contains nominal dimensions, which ensure nondestructive mating of the electrical and optical interfaces, and functional operability of the electrical interface. Funct

10、ional operability of the optical interface is dependent upon fiber preparation and termination and is, therefore, not guaranteed by this document. In addition, this connector has three following characteristics in structure. a) Ball-lock mechanism: If metal residue or small particles of dust contami

11、nate the end face of the fiber, the optical power may decrease, and the risk of a communication error increase. The Ball-lock mechanism used is intended to decrease the occurrence of metal residue created by connecting or disconnecting. b) Position with Shell-key guide groove and Optical ferrule wit

12、h regard to Jack connector: The Shell-key guide groove is located on the outside of the jack connector so that if metal residue is created by the mating process, there is very low probability of it contamination the optical ferrule which is covered by Shell. (As shown in Figure 2) c) Protective mech

13、anism for waterproof with regard to Plug connector The Waterproofing plane is located inside the extremities of the outer shell, so that it is protected in the event that the connector is dropped in an unmated condition. (As shown in Figure 1) The connector described in this document is intended for

14、 use primarily with the hybrid fiber optic camera cable described in SMPTE 311M; however, this connector may be used independently to meet other requirements. 2 Conformance Notation Normative text is text that describes elements of the design that are indispensable or contains the conformance langua

15、ge 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 affecting interoperability. Informative text does not contain any conformance keywords. All text in this docume

16、nt 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“ indicate requirements strictly to be followed in order to conform to the document and from which no deviation

17、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 that a certain course of action is preferred but not necessarily required; or that (in the negative form) a certai

18、n 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 “reserved” indicates a provision that is not defined at this time, shall not be used, and may be defined in the

19、future. The keyword “forbidden” indicates “reserved” and in addition indicates that the provision will never be defined in the future. RDD 16-2008 Page 4 of 14 pages A conformant implementation according to this document is one that includes all mandatory provisions (“shall“) and, if implemented, al

20、l 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 of the types of normative information in this document shall be as follows. Normat
