1 Scope
This Standard specifies the classification, general requirements, performance
requirements, test standards and methods, marks, packaging, transportation
and storage requirements of field-mountable optical fiber connectors (optical
field connectors for short, or quick connectors for short).
This Standard applies to the single-mode fiber optic field connector series
products.

3 Noun terms and abbreviations
3.1 Noun terms
3.1.1 field-mountable optical connector
A field-mountable optical connector (optical field connector for short) is a fiber
optic connector that is directly terminated at the construction site and
terminated by mechanical splicing or thermal fusion splicing.
Optical field connectors can be widely used in the occasions of fast termination
and interconnection of optical fibers or cables. They possess the same
connection performance as standard SC/LC connectors. They are compatible
with standard SC/LC connectors and sockets.
3.2 Abbreviations
The following abbreviations apply to this Standard:
FTTH Fiber To The Home
ODN Optical Distribution Network
4 Classification of optical field connectors
4.1 Classify by connector structure
According to the connector structure, it can be classified into the following types:
a) Plug type: including SC type, LC type, FC type;
b) Socket type: including straight (SC type, LC type, FC type), curved (SC
type, LC type, FC type).

field connectors shall be within 3 minutes.
5.2.2 Assembly success rate
The one-time assembly success rate of the optical field connector shall not be
less than 95% (for example, if 100 samples are assembled, the assembly failure
of up to 5 samples is allowed).
5.2.3 Repeatable assembly
The pre-installed optical mechanical splicing and straight-through optical field
connectors shall have repeatable assembly. Ensure that after an assembly
failure, it can be reworked and assembled again. And when repeated assembly,
it shall be easy to turn on.
Repeated assembly refers to turning on the assembled connector, remaking
the fiber end face according to the assembly procedure, and reassembling the
connector. Repeatable assembly shall be more than 5 times.
5.3 Working environment requirements
The environmental requirements for optical field connectors are as follows:
a) Working temperature: -40°C~+85°C;
b) Storage temperature: -40°C~+85°C;
c) Relative humidity: ≤95% (at +30°C);
d) Atmospheric pressure: 62kPa~106kPa.
5.4 Material requirements
The materials used for optical field connectors shall meet the following
requirements:
a) The refractive index of the refractive index matching material needs to be
close to the core. The material shall be stable and reliable for 25 years;
b) The combustion performance of plastic parts used in optical field
connectors shall meet the requirements of GB/T 5169.5-2008. The
duration of applying the test flame is 10s;
c) They shall comply with RoHS standards, no pollution to the environment,
and comply with relevant environmental protection standards;
d) When the finished product is damaged, its parts are not allowed to cause
harm to people.

measurement is carried out under the standard atmospheric pressure
conditions specified in GB/T 2421.1-2008. The accuracy of the measuring
instruments and meters shall meet the requirements and be calibrated regularly.
7.1.2 Test light source and tail fiber
LD light source is used for measurement. Its peak wavelength is
1310nm/1550nm.
The tail fiber connected to the light source shall be a single-mode fiber. To
eliminate the influence of the cladding mode on the measurement, a s...
