Southwest China is one of the seven natural geographical zones of China and central China. It faces central China in the east, northwest China in the north, including Chongqing Municipality, Sichuan Province, Guizhou Province, Yunnan Province and Tibet Autonomous Region. The southwest China is mainly mountainous, with complex topographic structure and rich in natural resources.

This project is a cooperation with a research institute in southwest China, which is a comprehensive research institute based on developing cutting-edge science and technology of national defense. The cooperation with the research institute fully shows the professionalism and reliability of XYT’s transmission equipment.In order to solve the needs of the research institute's special network upgrade, The active wave transmission solotiondesigned by XYT considers from saving user expenses, At the same time, it also ensures the applicability of the system, Convenience of remote network pipe system, simplicity of equipment operation and maintenance, and reliable durability of equipment operation; XYT’s equipment is highly integrated in design, Each equipment room is clearly structured, Fully standardized, Easy for system integration and network expansion; Core business can directly connect and other characteristics (transparent transmission); After the early technical scheme communication and discussion, feasibility study, To the mid-term bidding, Finally, under the layers of assessment and screening, The institute eventually chose Fiber Beitong, And signed a strategic cooperation with XYT in August 2021, The upgrade was successfully completed in October.

requirement analysis

1. To transform and upgrade the original network for the maintenance channel, it can provide 4-core optical fiber for multi-business transmission.

2. Put forward telephone network, IPTV, monitoring network, network (inside, external), video conferencing, network management, and meet the follow-up independent expansion.

3. Transmission has been unable to carry the rapidly growing IP business, and cannot monitor the operation of network equipment in real time.

4. Link bandwidth should be improved to ensure the stability, security and reliability of production data; to ensure the smooth delay of dynamic monitoring video retransmission and low no lag.

5. Each station is far away and difficult to maintain. It must strengthen the station line protection function and improve the network stability.

6. Remote management system must be realized to improve maintainability and reduce maintenance costs.

Business challenges and difficulties

1. Because of the limited optical cable resources, can provide 4 cores, needs to be completed in business expansion in a short time.

2. The distance between stations is remote. The special network should realize the line protection function. In the case of the main optical road failure, the network switch to the standby optical road automatically to maintain the transmission of the optical signal.

3. The original equipment is gradually aging, and the function cannot meet the service requirements of the existing users for various new business. Neither the original equipment cannot be upgraded, which can be upgraded through the equipment ofSharetop.

4. The epidemic has spread across the country and is under great pressure. The company and technical engineers need to ensure the successful upgrading and transformation of the special network under strict compliance with the national epidemic prevention policies and systems.

Solution and advantages

1. The scheme adopts a highly integrated active wave division device network, which occupies less space and has faster debugging.Each site can realize the upload and download business, and each device is equipped with an independent internal network IP, which can realize the remote full-site visual management.

2. Adopt DWDM (dense wave split board card), telephone, IPTV, network (internal, external), industrial control, video conferencing, network pipe, video monitoring expansion at the same time, only occupy optical fiber two-core optical fiber, to reserve more fiber core resources for users.

3. Each site is equipped with an OTU business board, which can monitor the luminescence of each wave light separation module on the side of the line, realize rapid fault positioning, accurate site maintenance, and greatly save time and cost.

4. Add sites with high line loss and EDFA fiber amplifier to achieve long-distance communication.

5. The main stations shall be equipped with OLP optical line protection board card to realize the main standby road switching protection of the site.

6. Strictly abide by national epidemic prevention rules and regulations, and do not relax in epidemic prevention and control.Wear masks in public places and conduct nucleic acid tests regularly.

Scheme topology

Flexible use of WDM upgrade and capacity expansion solution network structure, streamline the number of customer sites, save investment; stronger business interference and interference ability; low switching delay, zero packet loss, no line loss, guaranteed delay; card scheduling, production scheduling, video business scheduling, priority to key business; two-way authentication to effectively prevent network attacks and protect core data security.

Implementation form

1. 4U active wave subsystem for central sites A, B, and stations C, D, E, F and G, with NMU network management system to realize equipment monitoring and management.

2. Insert the OTU service wavelength conversion board on both the 4U and 2U chassis to convert the gray and light module wavelength into the color light module wavelength.

3. According to the characteristics of the wave division multiplexer that can synthesize two or more light carrier signals with different wavelengths of one wavelength, we transmit the color light module through the wave division.

4. Before receiving the signal, we use the OLP optical line protection board card.It can automatically switch to the standby light road in the case of the main light road failure, to maintain the transmission of the light signal.The real-time transmission of the line is guaranteed.

Scheme acceptance and summary

The special network upgrading and transformation project of the institute was undertaken by Shenzhen Sharetop Technology Co., Ltd. Under the direct leadership and support of the institute, the work of scheme communication and design, project bidding, equipment installation and commissioning, and operation acceptance was completed.The project is responsible for the installation and debugging of the installation and debugging.Items include machine frame, DWDM wave split multiplexer, jumper, EDFA magnifying board card, OLP light protection board card, OTU board card, dispersion board card, etc.

The 4-core optical cable shall be provided by Party A himself, and Party B shall be responsible for the installation and commissioning.The project wiring is strictly in accordance with relevant requirements, and all lines are clean, beautiful, reliable, standardized and in accordance with national regulations.The switching delay is low, 0 packet loss, no line loss, the delay is guaranteed; card scheduling, production scheduling, video business scheduling, priority to key business, and the system works normally 24 hours a day.

Since its establishment in 2012, Shenzhen Sharetop Technology has been focusing on the field of optical transmission, providing customers with optical transmission products and solutions, as well as after-sales installation and debugging services.In recent years, government and enterprise units have responded to the call of national digital transformation and upgrading to upgrade and expand their intranet.XYT follows the pace of the country, and has formulated more applicable and more scenario optical transmission solutions for various industries for all types of government and enterprises to help government and enterprises carry out digital transformation and upgrade and expansion of backbone optical transmission lines.In recent years, the products ofSharetop Technology have been widely used in systems such as State Grid, Water Bureau, National Energy Administration, Public Inspection and other government and enterprise units.
