New technologies of Huawei Optical Fiber Access Network

Huawei fiber-optic access networks are quite common. So I have studied the New Technology of Huawei fiber-optic access networks. Here I will share it with you and hope it will be useful to you. Optical fiber replacement for copper cables is itself a solution for saving energy and reducing consumption. In addition, all aspects of the network need green design to build a green end-to-end network.

As mentioned above, the large capacity and long-distance communication advantages of Huawei optical fiber access network must be achieved through the combination of ultra-large capacity olts. At present, the largest capacity OLT in the industry has reached the T-bit specification, A single frame can support a maximum of 10 thousand users. The ultra-large capacity means that the OLT can be placed in the central data center in one step. In combination with the advantages of Optical Fiber distance, it can truly reduce the number of node data centers, in this way, the rental cost and total power consumption of the IDC room are significantly reduced. At the same time, the work that originally needed to go out to the site for maintenance can be completed in the central IDC, saving the trouble of staff moving, and saves energy consumption.

FTTB in China will be one of the mainstream construction models. The promotion of FTTB will further bring access nodes closer to end users, so more communication devices will appear in the corridor of the community. Because corridor applications are closer to residents, there is usually no good heat dissipation condition. Communication devices usually have a large amount of heat dissipation. For effective heat dissipation, they are usually equipped with a big-leaf fan. However, the operation of the large page fan will produce continuous noise pollution, affecting the normal life of residents. In addition, consultation shows that the probability of device repair due to fan damage on the corridor is 20%.

Small troubles bring about big problems. Sending people, leaving cars, and returning to repair all bring unnecessary resource consumption to the society. Currently, no fan is designed for corridor applications. The benefit of fan-less design is that noise pollution is directly eliminated. Secondly, it directly avoids a series of problems caused by device repair due to fan damage, and saves energy. The average power consumption of each fan is 5 W for two fans per device. If 0.1 million fans are used across the network, the whole network can save nearly 4.5 million kilowatt-hours.

In the general trend of network convergence, multi-function, high integration, large capacity, high bandwidth, wide coverage, and green energy conservation have become the basic features of devices, especially for Huawei optical fiber access network layer devices deployed in massive volumes, these features directly affect the operator's network architecture, deployment plan, and even investment plan. As a leader in the IP address and Huawei's optical fiber access network era, Huawei has become the world's leading FTTx solution provider for the most commercial projects among the world's leading carriers, providing users with new high-speed internet and triple-play services Huawei optical fiber access network capabilities.
