DWDM波分系统是一种最新的光通信技术，它采用了ITU-T G.694.1推荐的频谱网格，以实现高密度、高速率的波分多路复用（WDM）应用。这一推荐标准是ITU-T G系列推荐标准中关于传输系统和媒体、数字系统和网络的一部分。这些推荐标准旨在为光通信领域提供统一的规范，以便不同厂商和系统之间的互操作性和兼容性。根据ITU-T G.694.1推荐的频谱网格，DWDM波分系统可以实现在光纤上进行密集的波长分集，从而大大提高传输容量和效率。这种高密度的频谱分配使得系统能够实现更多的通道并行传输，满足不断增长的数据传输需求。此外，ITU-T G.694.1标准也规定了光系统的特性，包括波长范围、频谱间隔、波长精度等，确保了系统的性能和稳定性。除了频谱网格的规范，ITU-T G.694.1还包括了关于光传输系统的其他特性和要求，如光纤的损耗、色散、非线性等参数的规定。这些规范为DWDM波分系统的设计、实施和运维提供了重要的指导，保证了系统在不同环境和应用场景下的可靠性和稳定性。总的来说，ITU-T G.694.1推荐标准为DWDM波分系统的发展和应用提供了指导和支持。这一最新的技术将为未来的光通信网络提供更高的带宽和更大的灵活性，满足不断增长的数据传输需求，推动数字化社会的发展。作为国际通信标准组织的一份子，ITU-T G.694.1的推荐标准将在全球范围内推动DWDM波分系统的应用和发展，促进全球通信基础设施的升级和优化。DWDM波分系统的应用将促进不同国家和地区之间的互联互通，为数字化经济和社会的发展提供重要支撑。同时，ITU-T G.694.1的推荐标准也将为行业内的各个参与者提供了一致的规范和指导，促进了行业的良性发展和竞争。在未来，我们期待DWDM波分系统在光通信领域发挥更大的作用，为人们的生活和工作带来更多的便利和可能性。ITU-T G.694.1这一推荐标准的出台必将推动DWDM波分系统技术的广泛应用和发展，为全球通信行业的可持续发展和进步贡献力量。

ii Rec. ITU-T G.694.1 (10/2020)

FOREWORD

The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of

telecommunications, information and communication technologies (ICTs). The ITU Telecommunication

Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical,

operating and tariff questions and issuing Recommendations on them with a view to standardizing

telecommunications on a worldwide basis.

The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes

the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.

The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.

In some areas of information technology which fall within ITU-T's purview, the necessary standards are

prepared on a collaborative basis with ISO and IEC.

NOTE

In this Recommendation, the expression "Administration" is used for conciseness to indicate both a

telecommunication administration and a recognized operating agency.

Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain

mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the

Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other

obligatory language such as "must" and the negative equivalents are used to express requirements. The use of

such words does not suggest that compliance with the Recommendation is required of any party.

INTELLECTUAL PROPERTY RIGHTS

ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve

the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or

applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of

the Recommendation development process.

As of the date of approval of this Recommendation, ITU had not received notice of intellectual property,

protected by patents, which may be required to implement this Recommendation. However, implementers are

cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB

patent database at http://www.itu.int/ITU-T/ipr/.
