A new LAN networking mode based on PON technology POL
POL passive optical LAN is applying PON technology to replace traditional integrated wiring in the local area network. The distinguishing feature of the PON passive optical network is that it realizes a point-to-multipoint architecture. It uses passive optical fiber splitters to enable a single optical fiber to Serve multiple endpoints.
Implementing the overall policy of "Optical Advance and Copper Retirement" has led to the replacement of some copper cables with optical cables in the market infrastructure construction. At the same time, traditional switches and other network equipment have gradually been replaced by PON equipment, forming a new POL (passive all-optical network). ) solution. POL applies the PON technology originally used for the last mile of the metropolitan area network to the integrated cabling of the local area network, connecting the optical fiber directly to the user's work area.
POL extends the PON technology originally used in fixed communication networks to local area networks, expanding the application scenarios of PON and enabling PON to play its advantages in more fields:
1. All-optical industrial network
FTTM stands for "Fiber To The Machine", and is also known as "F5G All-Optical Industrial Network". Simply put, FTTM uses optical fiber to replace traditional copper wires, extending the optical fiber to the end machine, and realizing the true "all-optical industrial network" throughout the process.
As a typical technology of F5G (fifth-generation fixed communication network) technology for industrial scenarios, FTTM will help the entire industry to reduce costs increase efficiency, and promote high-quality economic development. Optical networks have the advantages of high bandwidth, low latency, low loss, easy operation and maintenance, and anti-interference. These advantages can meet the network needs of enterprises in the process of intelligent manufacturing transformation and upgrading while ensuring the security, convenience, and ease of use of their networks.
2. Data Center Interconnect
To meet the needs of cross-regional operations, user access, and off-site disaster recovery, more and more organizations and enterprises are deploying multiple data centers in different regions. At this time, it is necessary to interconnect multiple data centers. The interconnection of data centers will be an inevitable trend in the development of my country's intelligent era in the future. Moreover, the interconnection of data centers, especially the interconnection between cities, will also be the most important application scenario of F5G in the future.
In the intelligent era, the digital transformation of the industry and new businesses have brought massive data. More and more Internet giants, lCPs, and enterprises are beginning to seek DCI (data center interconnection) solutions to provide stable, reliable, and ultra-wide connections for their data centers. While considering bandwidth requirements, they also need to consider minimalist deployment, intelligent operation and maintenance, and security issues. Therefore, intelligent, ultra-wide, and minimalist data center interconnection is imperative and is the key cornerstone for the achievement of enterprise data center strategies. This aspect happens to be the specialty of F5G passive optical LAN (POL) technology.
3. All-optical campus
F5G all-optical park gives a new definition: F5G all-optical park is a park network built with single-mode optical fiber as the medium, using 10G GPON (compatible with GPON) and Wi-Fi 6 as the fifth-generation fixed access technology. It mainly includes optical line terminal OLT, passive optical distribution network ODN, optical network unit ONU, etc. It can uniformly carry multiple services such as data, voice, video, etc., and has the characteristics of simple architecture, easy evolution, intelligent operation and maintenance, and high reliability.
F5G all-optical park is mainly used for enterprise access customers. It provides various interfaces and various forms of ONU equipment according to customer needs. In addition, the intelligence and automation of the park have brought about a significant increase in the types of services. Park transportation, access control, security, monitoring, Wi-Fi coverage, voice, and other services have put forward high requirements on the network service carrying capacity. Compared with the home broadband scenario, the F5G all-optical park has higher security operation, and maintenance requirements and provides more terminal forms and installation methods.
In addition to the above three common application scenarios, POL can also be applied to other scenarios. TC has been deeply studying POL for many years and has perfect and mature solutions, which can provide networking solutions for different scenarios. Combined with TC's many years of practical experience, POL solutions can be made more practical and convenient for operation and maintenance!
