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
Main drafters of this Part. Liang Chenhuan, Xu Qiushuang.

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 l......
