On April 14, the science and Technology Department of the Ministry of industry and information technology announced 10 national standards and 64 industry standards for the communication industry. According to the standard development and revision plan, relevant standardization technical organizations have completed the preparation and revision of 10 national standards such as Raman fiber amplifier for communication industry and 64 industry standards such as calculation method for atmospheric and rainfall attenuation of satellite communication link. Before approval and release, in order to further listen to the opinions of all sectors of the society, they are hereby publicized. The deadline is May 14, 2020.
According to the published documents, the 10 national standards of the industry involve Raman fiber amplifier, specification of optical fiber test method, application scenarios and requirements of quantum secure communication, smart city, basic specification of optical amplifier test method, etc.
The names and main contents of 64 communication industry standards involve optical module standards, including: optical module, basic telecom enterprise security, Internet security, content distribution network (CDN) and Internet of vehicles, public cloud services, access network, big data and other industry requirements, test methods and basic specifications. Article 55, 56 and 57 involve the technical requirements, test and detection of optical modules.
The first mock exam the first mock exam of the 55.YD/T 2798.2-2020, the multi wavelength optical transceiver module of optical communication is applicable to the single mode optical fiber, the modulating NRZ or PAM4, the multi wavelength optical transceiver module, and the other modulating optical modules can also be used in reference.
56. YD / T 3356.2-2020100gb / s and above optical transceiver module, which specifies the terms and definitions, technical requirements, test methods, reliability test, inspection rules, marking, packaging, transportation and storage requirements of 4 × 25gb / s LR4 optical transceiver module. It is suitable for 4 × 25gb / s LR4 optical transceiver module.
57.YD/T 2759.2-2020, the first mock exam is a single fiber bidirectional transceiver module 25Gb/s.
