Foreword
YD/T 1272 “Optical Fiber Connector” is divided into 3 parts:
— Part 1: Type LC;
— Part 2: Type MT-RJ;
— Part 3: Type SC.
This Part is Part 3 of YD/T 1272.
This Part is the revision to YD/T 895-1997 “Technical Conditions of SC/PC Single-mode Optical Fiber Connector”. The revision refers to EC 61754-4:2002-03 “Optical Fiber Connector Interface Part 4: SC Connector Cluster”, IEC 60874-19-1:2003-01 “Detailed Specifications of SC/PC (Active Dual-core) Multimode Optical Fiber Ala and Alb Standard Terminated Fiber Optical Cord Connector”, IEC 60874-14-5:1997-06 “Detailed Specification of SC/PC Single-Mode Optical Fiber B1 Unadjusted Terminated Fiber Optical Connector”, IEC 60874-14-3:1997-06 “Detailed Specification of SC Single-Mode Optical Fiber Single-Core Fiber Optical Adaptor” and IEC 60875-14-10:1999-09 “Detailed Specification of SC/APC Unadjusted 8° Terminal Single-Mode Optical Fiber B1 Fiber Optical Tail Fiber or Jumper Connector”.
Compared with YD/T 895-1997, main changes of this Part are as follows:
— The scope in chapter 1 contains more connector types than previous standard; this Part applies to type-SC optical fiber connector cluster products.
— Add 3.7 Definition of “active device receptacle”.
— Re-write 4.1 Classifications.
— Delete the relevant provisions in original 4.2.1.4 Color and 4.5 optical fiber and cable.
— Change the previous clause 4.6 to clause 4.5; and redefine optical properties of type-SC connector cluster products.
— Revise 6.3 Measurement and test conditions; add 6.3.2 Single-mode connector measurement and test light source, 6.3.3 Multi-mode connector measurement and test light source, and 6.3.4 Cleaning before measurement.
— Revise the duration in 6.6.1 and 6.6.2, conditions in a) of 6.6.6, load in 6.6.10, load application point in test figure, and load in 6.6.10 by referring to the latest version of relevant standard in IEC60874.
— Revise 8.1.1.
— Section 4.2 “Interface graphics and coordinating dimensions” in this Part adopts IEC 61754-4:2003-03, however, there are revisions; the main changes are as follows:
(1) Add the plug-pin optical fiber’s subsidence schematic diagram; and mark out the subsidence dimension BK;
(2) Make editorial revisions to interface order and combination; and combine the same parts;
(3) Use decimal point symbol “.” to replace the decimal point symbol “, ”;
(4) Delete the “foreword” and “scope” in IEC 61754-4:2003-03, interface descriptive text in chapter 3, chapter 4, chapter 5 and chapter 6, and “Plug, adapter and receptacle’s interaction allocation table”.
This Part is one of series standards of optical fiber connectors; the standards that have been published are listed as follows:
(1) YD/T 717-94 “PC Single-mode Optical Fiber and Cable Connector”.
(2) YD/T 826-1996 “Technical Conditions of FC/PC Single-mode Optical Fiber and Cable Connector”.
(3) YD/T 895-1997 “Technical Conditions of SC/PC Single-mode Optical Fiber Connector”.
(4) YD/T 896-1997 “Technical Conditions of FC/APC Optical Fiber Connector”.
(5) YD/T 987-1998 “Technical Conditions of ST/PC Single-mode Optical Fiber Connector”.
(6) YD/T 1200-2002 “Technical Conditions of MU Single-mode Optical Fiber Connector”.
(7) YD/T 1272 “Optical Fiber Connector”
— Part 1: Type LC.
— Part 2: Type MT-RJ.
— Type 3: Type SC.
This Part replaces YD/T 895-1997 from the date of implementation.

3 Terms and definitions
For the purpose of this section, the following terms and definitions shall apply.
3.1 Type SC optical fiber connector
SC connector is a kind of plug-in connector that is composed based on single-core plug and adaptor. Its feature is adopting rectangular structure and elastic clamp locking mechanism, including a coupling guide-key and an elastic plug-pin in the direction of optical axis. Typical outer diameter nominal value of plug-pin is 2.500mm; plug has a plug-in switch, which may be used for positioning and limiting of relevant position between connector and matching element. Optical center-alignment device of connector is a rigid inner bore or elastic sheath.
For tail-fiber that uses single-mode optical fiber connector, it is called type-SC single-mode optical fiber connector; tail-fiber multimode optical fibber connector is called type-SC multimode optical fiber connector; optical connector of which the plug-pin end-face is spherical is called type-SC/PC optical fiber connector; optical fiber connector of which the plug end-face is beveled spherical is called type-SC/APC optical fiber connector.
3.2 Reference plug, adapter
Plug or adapter that are precision-manufactured or selected for measurement.
3.3 Mating face dimensions
Dimensions of components and parts that determine the plug mating between a set of optical fiber connector elements.
3.4 Concentricity error
The distance between optical fiber mandrel and plug-pin axis.
3.5 Angular alignment error
Angular deviation between excitation beam axis and plug-pin axis.
3.6 Eccentricity of spherical endface top
The distance between convex spherical vertex of plug-pin and plug-pin axis.
3.7 Active device receptacle
Connector plug-receptacle that is used for active-devices, components and modules.
4 Requirements
4.1 Classification
