The course is organized in a modular form and is divided into four modules: optical fiber communication system, SDH technology and equipment, OTN technology and equipment, and optical fiber communication development.

Module 1: optical fiber communication system. This module mainly introduces the basic components of optical fiber communication system, including optical fiber, light source, optical detector, optical device and optical fiber communication system model.

Module 2:SDH technology and equipment. This module mainly introduces the technical principle of SDH, the introduction of common equipment of SDH, SDH networking and service configuration, SDH self-healing protection, etc., and there are six skills and practical tasks: SDH networking, service configuration, channel protection configuration, multiplexing segment protection, clock configuration and official configuration.

Module 3:OTN technology and equipment. This module mainly introduces the principle of DWDM system, the basic principle of OTN, the introduction of typical OTN equipment and the application of OTN network, and includes five technical and practical tasks: signal flow and optical fiber connection, optical power adjustment, OTN system optical power adjustment, OTN optical layer protection configuration, OTN electric layer protection configuration.

Module 4: the development of optical fiber communication. This module mainly introduces the latest developments and technologies of the development of optical fiber communication, and then introduces the latest developments of the industry, and also gives a reference for the follow-up learning direction.

Every week, the teaching team will lead a new unit of learning, gradual progress, coupled with rich learning resources, we can choose the right time to learn and communicate.

1. For the students majoring in communication, they can have the principle of optical communication system, the knowledge of optical transmission equipment, and the ability of maintenance of optical transmission equipment through the study of the course.

2. Teachers engaged in relevant teaching should make use of the rich materials and resources in the curriculum to provide conditions for teaching reform and mixed teaching.

3. For optical fiber communications network and equipment, engineering design and other related positions, improve vocational skills, participate in vocational skills competition.

This course is a communication major course, learners should have basic knowledge related to communication major, such as "introduction to communication systems", "communication principles" and so on.

1. How should I study?

The MOOC course is essentially a complete online course, which requires students to have certain online conditions and be able to watch teaching videos smoothly. All important information about the course will be published in the form of an announcement and a copy will be sent to the registered email address of the student. Please check it in time.

Special reminder: please submit the unit test, unit assignment and final exam on time. Please submit your homework in advance if you have problems with network speed. Do not wait until the last few minutes to hand in your homework, which will cause the submission to be unsuccessful. Cut!

2. What should I do if I encounter problems in the process of learning?

If there are any questions to be discussed in the course discussion area, the course platform will become an area for everyone to communicate and learn, and the teacher team will also participate in it.
