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). China Telecom Page 13 of 29 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. China Telecom Page 17 of 29 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 small circle of Φ30mm is marked on the tail fiber. 7.1.3 Standard connectors When testing the optical performance of SC optical field connectors, the standard connectors used shall meet the requirements of 4.3 in YD/T 1272.3- 2005. When testing the optical performance of LC-type optical field connectors, the standard connectors used shall meet the requirements of 4.3 in YD/T 1272.1-2003. 7.1.4 Preparation before measurement Before measurement, use lint-free fiber paper or absorbent cotton to wipe and clean the pin body and the end surface and the inner surface of the adapter sleeve. Use absolute alcohol to scrub if necessary. 7.1.5 Specimen The samples for mechanical performance test and environmental performance test shall be the samples that pass the insertion loss and return loss test after the on-site assembly test. 7.2 Appearance and size inspection The appearance of the assembled optical field connector shall be smooth, clean, free of oil and burrs, without scars and cracks, with bright colors, and good consistency. Each component combination needs to be flat. The insertion and removal of the adapter needs to be smooth and easy. The connection is strong. The switch works normally. Measure the length of the assembled fiber optic field connector with a caliper. The length shall meet the requirements of 5.1.1. 7.3 Insertion loss measurement The insertion loss of the optical field connector is measured according to one China Telecom Page 19 of 29 In the formula: The unit of P1 and P0 is mw, and the unit of insertion loss is dB. 7.4 Echo wave loss measurement Measure according to the method specified in 6.5 of YD/T 1272.3-2005. The indicators shall meet the requirements of Table 2b. 7.5 High temperature Perform high temperature measurement of optical field connectors as follows: a) Conditions - Temperature: +85°C; - Duration: 96h. b) Procedures - Pretreat the specimen at room temperature. Measure the insertion loss value and echo wave loss value of the specimen as the original value before the test; - Place the specimen in a thermostatic oven with an accuracy of ±2°C. The temperature is 85°C. Keep constant temperature for 96 hours. During the test, test and record the insertion loss and echo wave loss of the specimen. After the test is over, take the specimen out and place it in a room temperature environment for 2 hours. Test and record the insertion loss and echo wave loss values. c) Test results - The test results of insertion loss and echo wave loss of the specimen during and after the test shall meet the requirements of Table 2.......Source: https://www.ChineseStandard.net/PDF.aspx/QCT2299-2010 |
