Technology route innovation

Ethernet color light brings better choice for campus network upgrade

Minimalist light that continues to innovate and evolve

Ma Wenqiang, Product Director of the Minimalist Optical Solution of Ruijie Networks Wireless Switching Products Division, officially released the Minimalist Ethernet All-Optical 3.X solution at the press conference. The new Minimalist Optical 3.X supports three architectures: optical modification, optical hybrid, and color optical. It has the advantages of easy network expansion, long-distance deployment, and true 10G access to the room, and is suitable for network deployment scenarios in different industries. It proactively introduces Ethernet color optical technology in the park, effectively reducing the wiring cost between the central computer room and each building, and ensuring exclusive bandwidth. On the basis of realizing centralized power supply at the access layer, it can use color optical centralized power supply technology to realize passive power supply between weak current rooms and centralized power supply between strong current rooms, and can also realize long-distance optical fiber transmission and PoE power supply through the optoelectronic separation star host with optoelectronic hybrid cable, eliminating the worries of users in digital transformation.

01Simple Link Ethernet Color Light Technology Convergence Layer Passive

In the process of developing smart parks, the internal lines, architecture and number of devices in the park network will become more complex and diversified due to the development of business. For many parks that have been built for a long time, network upgrades and renovations are often limited by the current architecture, equipment management and space resources. The number of backbone optical fibers is small and resources are tight. Renovation requires re-drilling and wiring, which makes construction difficult and takes a long time.

Minimalist Optics introduces Ethernet color optical technology that combines CWDM and Ethernet full-optical, transmitting 8 pairs of optical signals of different wavelengths in one optical fiber, replacing the previous 8 optical fibers. It can help the park effectively save more than 85% of backbone optical cable resources, and can also greatly optimize the internal equipment management and space of the weak current well/room, avoiding the trouble of re-drilling the well and wiring.

At the same time, the minimalist optical solution under the Ethernet color optical technology adopts a large two-layer architecture as a whole, replacing the original active aggregation of the building with passive transparent aggregation, truly realizing the passive aggregation node and zero maintenance of the weak current room; and through the integration of wavelength division technology and switches, the density of core ports and the total number of interfaces are improved. The core side adopts a hyper-convergence module, and a single port can be connected to 8 indoor switches by connecting one optical fiber . The original 8 optical ports on the core side are replaced with an existing hyper-aggregation module, which greatly reduces the number of ports occupied and the number of jumpers on the core side, making the deployment method simpler and the operation and maintenance work lighter.

02Better experience "breaks through" campus network requirements

•“Colorful Light + Wi-Fi 7” : Through the combination of wired all-optical network and wireless Wi-Fi 7, the backbone network adopts a large two-layer architecture, supports 2.5G/10G into the room, and the terminal matches the new generation of Wi-Fi 7 AP in multiple scenarios, using the all-optical network to provide performance support for high-speed wireless.

•“Colorful light + power supply” : The colorful light + newly launched centralized power supply host created by transparent convergence equipment realizes centralized power supply for access layer equipment, and makes the responsibilities of weak current and strong current management clear; the star host is equipped with an optoelectronic hybrid cable to realize long-distance fiber optic transmission + PoE power supply, which is convenient for expansion according to business needs.

•“Colorful Light + Operation and Maintenance” : The INC network intent commander and built-in intelligent operation and maintenance system EMB equipped with Minimalist Light 3.X create a one-stop management and operation environment for network equipment such as switching, wireless, routing and security for network administrators, and provide a package of services including business startup, network monitoring, and network operation and maintenance, as well as optical link detection and operation and maintenance, terminal status/location visualization and other means to help network administrators achieve efficient operation and maintenance.

03Reliable and secure terminal access is easier

When a terminal accesses the network, it only needs three steps: " apply - allocate IP, configure policy - approve network access ". The approval time is reduced from 30 minutes to 2 minutes. At the same time, access policies and authorizations can be visually configured based on terminal information to ensure network security.

"Colorful" minimalist light helps thousands of industries

At the press conference, Xiong Wei, Technical Director of Education Industry, Hu Bo, Technical Director of Enterprise Industry, and Yuan Minxue, Technical Director of Medical Industry of Ruijie Networks' EBG Strategy MKT and Solutions Department, respectively shared the innovative practices of the minimalist Ethernet all-optical solution for the three major industries of education, enterprise, and medical.

Education Industry

Xiong Wei, technical director of the education industry, used projects of Xihua University, Nanjing University of Technology, and the Affiliated Middle School of South China Normal University to illustrate the application of Ethernet all-optical network construction in colleges and universities and primary and secondary schools:

Starting from the "Digital Xihua" strategy, Xihua University upgraded and renovated 29 buildings with more than 2,000 rooms through a minimalist Ethernet all-optical solution. At present, the school has realized 100G backbone networking, 80G color optical transmission to buildings, and 10G optical equipment deployment in rooms, creating a new campus network that is "integrated", "high-speed", "flexible" and "easy to maintain".

The campus of Nanjing Tech University is built on the mountain, with scattered buildings and weak current rooms and regional convergence. If there is a power outage or other faults, operation and maintenance will be difficult and time-consuming. Once the network is disconnected, it will affect the normal teaching business and daily life of teachers and students. The school relies on Ethernet color light technology and equipment centralized power supply solutions to achieve the separation of data and power supply deployment of equipment. Data goes to the weak current room to achieve full passiveness, and power supply goes to the strong current room, which is managed by the logistics department, greatly reducing the pressure of operation and maintenance and improving network stability.

The Affiliated Middle School of South China Normal University has chosen Ruijie's simplified optical solution for the construction of the new campus network. Now, more than 300 simplified optical access switches and 80 color optical devices are in operation in the school, supporting daily education and teaching. The core side uses hyper-aggregated switches and all-optical networking. The high bandwidth and low latency characteristics meet the development needs of smart campuses in the next 5-10 years; the weak current room side uses Ethernet color optical technology to achieve passive aggregation layer, avoiding the impact of humid climate and frequent typhoons and rainstorms on equipment maintenance; the access side has exclusive 10G/1G bandwidth into the room, and the information points in the classroom are accessed nearby, reducing the pressure on the bridge.

Enterprise Industry

Hu Bo, technical director of the enterprise industry , introduced that the Simplified Ethernet All-Optical 3.X solution has been adapted to multiple scenarios in the enterprise industry in terms of solutions, architecture, and products for the construction of enterprise intelligent campus networks. He shared the three core values ​​of Simplified Optical 3.X in the enterprise industry with the practical case of Trina Solar Co., Ltd.:

• Flexible business support : In response to the flexible production needs of enterprise workshops, the overall solution has made grid deployment in the network and equipment, providing data and power supply over long distances through time hosts and optical-electrical hybrid cables. Adjusting and changing lines only requires jumper wires at the end, and adding new businesses does not require separate deployment of high-voltage/UPS systems, reducing TCO by 20%;

• Industrial-grade stability and reliability : The production environment is complex, and the network equipment has very high requirements for high temperature resistance and dust resistance. In addition, the production area operates 24/7, so the network must be designed with high reliability. Ruijie provides switching equipment with IP50 protection level to meet the requirements of high temperature resistance, dust resistance, and electromagnetic interference resistance in production scenarios, improving business stability by 50%.

Medical Industry

Yuan Minxue, technical director of the medical industry, summarized the adaptation value of minimalist light in core medical scenarios such as medical imaging, smart wards, and outpatient clinics based on the Ethernet all-optical practices in three hospitals: Wuwei Cancer Hospital of Gansu Province, Linyi Traditional Chinese Medicine Hospital, and Jining Hospital of Xiyuan Hospital of China Academy of Chinese Medical Sciences.

• Medical imaging : For Gansu Wuwei Cancer Hospital, instant reading of high-definition images is very important in the treatment of cancer with heavy ion technology. More than 70% of the data in clinical diagnosis and treatment comes from images, and the number of images in a CT or MR examination can reach 500 to 2,000. The file size of high-definition medical images/3D images is as high as several GB. The limitations of traditional network performance have seriously affected the efficiency of medical business. Through Ethernet all-optical deployment and 1:1 bandwidth access, the time from loading to opening a 1G image has been reduced from 5 minutes to 5 seconds, achieving a speed increase of nearly 60 times.

• Smart ward : As the construction of smart ward systems becomes mainstream, the large number of wired, wireless, and IoT access terminals in the wards have gradually increased the demand for internal ward networks. Linyi Traditional Chinese Medicine Hospital adopts a minimalist optical solution deployment, unified carrying of wired/wireless/IoT, and deploys PoE indoor optical switches in the room to facilitate business expansion and nearby access, avoiding the waste of ward resources due to network upgrades and renovations.

• Outpatient clinics : In order to improve the efficiency of medical services and improve the patient experience, frequent drilling and wiring affect the medical business, and the use of hubs and fool switches will bring more troubles to network stability and operation and maintenance. By introducing manageable remote modules into the room, the hospital can quickly achieve nearby expansion access of the indoor network, loop self-healing and remote management, and improve operation and maintenance efficiency by 60%.

•Multiple medical scenarios : Jining Hospital of Xiyuan Hospital of China Academy of Chinese Medical Sciences adopts a minimalist optical solution to achieve access to nearly 30,000 information points, providing business continuity guarantee for the full cycle of health management before, during and after diagnosis, and promoting the improvement of hospital service quality. 3,500 all-optical indoor switches are deployed to help the access side to expand flexibly; the floor aggregation is passive, and only 4 active weak current rooms need to be maintained in the entire hospital, simplifying operation and maintenance; dual 100G links are aggregated to achieve core 200G access to support the sustainable development of smart medical care.

The innovation of the simplified Ethernet all-optical 3.X solution, the development of Ethernet color optical technology and the launch of innovative new products will promote a new round of upgrades in the smart campus network. Ruijie Networks will also continue to iterate the simplified Ethernet all-optical solution to create more innovative and scenario-based network solutions and products for enterprise customers, and play a technological role in promoting the digitalization and intelligentization of various industries.
