Academician Yu Shaohua, academician of the Chinese Academy of Engineering and deputy director of Pengcheng Laboratory, pointed out in his speech that China is currently at the world's leading level in optical fiber communication systems and network applications, and the market share of Chinese enterprises in the field of optical fiber communication system equipment has ranked first
in the world.
However, in the field of optical communication simulation software, it mainly relies on foreign tools, and there are certain controlled risks
.
At present, artificial intelligence and optical communication are deeply integrated, intelligent analysis is an important trend in the evolution of optical communication simulation, and open source, intelligent, accurate and fast optical communication simulation software is a common demand
in the industry.
This seminar aims to promote the development of simulation software in China's optical communication industry, advocate open sharing, and contribute collective wisdom and strength
to the development of China's optical communication industry.

IFTS is a Python-based intelligent optical communication open source simulation tool, which aims to meet the needs
of scientists, optical communication engineers and researchers in related fields for optical communication simulation tools.
The platform includes functions such as signal origin coding modulation, fiber channel transmission, and receiving demodulation code, and provides a Pytorch-based simulation version with classic and AI dual modes, which allows users to use GPUs for simulation acceleration and naturally supports intelligent algorithm design
for optical communication.

IFTS main features

Compared with the existing mainstream optical communication simulation software, its main advantage is that the transmission, reception and transmission support and embedded AI algorithms, which can achieve fast and accurate simulation, and the underlying code is free and open source
.
The AI model in the simulation platform includes both a general AI algorithm library and an AI-based channel acceleration model
.
The AI algorithm library can support users to design their own AI algorithms and quickly verify
them in the simulation system.
Aiming at the pain point of slow simulation speed of traditional modeling algorithms, IFTS' AI channel acceleration model provides a solution
for fast and accurate channel simulation.
In multiple scenarios, the running time of AI channel models is only 1%
of that of traditional modeling algorithms.
Under different devices and different data length definitions, the degree of time optimization of AI models is different
.
In the best case, the AI channel model is even only one-thousandth of the time of traditional modeling algorithms
.

At present, IFTS can be used by universities for teaching and research, and can also be used by optical communication enterprises to carry out system design and performance optimization
.
Since its pre-release in October 2022, it has been downloaded and used
by more than ten companies, including China Telecom, Huawei, Fiberhome, Pengcheng Lab, Beijing University of Posts and Telecommunications, and Huazhong University of Science and Technology.
Dr.
Li Junjie, chief expert of optical transmission of China Telecom, tried the IFTS platform and commented in his report that "IFTS is a milestone product in the localization of optical communication simulation technology"
.
In the future, IFTS plans to continue to update, complete device effect simulation, add FEC compilation code module, establish a complete AI algorithm library, and realize the digital twin model of the experimental system
.
In addition, IFTS will further improve the online community and establish a platform
for feedback and exchange.
Finally, it is planned to build a powerful domestic optical communication open source simulation platform for free use in the whole industry, and contribute to solving the "stuck neck" problem of optical communication simulation software
