20. The network management of Huawei access products supports rogue ONU detection.

21. The OLT product MA5800 supports high-density 48-port GE and 8-port 10GE aggregation boards.

22. Compared with the traditional LAN network, the all-optical campus network has a cost advantage. The cost saving is mainly the saving of the equipment cost, and the cost of wiring is similar to that of the traditional network.

23. In the Internet era, with the development and popularization of cloud platforms, the traffic model of the campus network has undergone great changes. From the original horizontal traffic to vertical traffic, more and more traffic comes from outside the local area network.

24. All-optical network and optical reflector can automatically locate the optical fiber disconnection and fault point, and the fault location accuracy is within 10 meters.

25. All-optical network supports smooth upgrade of bandwidth, from GPON to 10G GPON, and from 10G GPON to 50G GPON, and the passive ODN network does not need to be changed.

26. POL is an enterprise local area network based on PON technology, which provides users with integrated data, voice, video and other weak current services through optical fibers. Through the POL solution, enterprises can combine different systems such as data, voice, video, and wireless access into one optical fiber network, which has incomparable advantages over other technologies.

27. The all-optical campus network solution is a multi-service integrated bearer network based on PON technology, positioned as a high-end access network solution specially developed by Huawei for the enterprise market.

28. PON is the abbreviation of Passive Optical Network, which is a point-to-point access method, that is, a P2P access method.

29. EPON and GPON are the two main PON technologies at present. Compared with EPON, GPON has advantages in terms of bandwidth, optical splitting ratio, standard perfection, etc. The upstream and downstream bandwidth of GPON is twice that of EPON.

30. FTTO is the abbreviation of Fiber-to-the-Office, mainly for commercial users, or the construction of office networks of hospitals, banks and government enterprises, using ONUs with rich interfaces to be deployed in offices to meet broadband, voice, and video.

31. The EA/EG series access products are Huawei's proprietary brand for enterprise access companies, which can better match the business needs of enterprises and effectively reduce operators' cross-selling.

32. POL is an all-optical local area network launched for enterprise network application scenarios, which can be widely used in network construction in education, medical care, buildings, and parks.

33. ODN is an important part of the POL solution, the networking is flexible and convenient, the transmission distance is long, and the optical fiber transmission does not require power supply, but the ODN equipment still needs power supply.

34. The advantages of PON access are low cost and high reliability.

35. Huawei use Huawei's self-developed chips for the access to MA5800 series products.

36. Huawei's all-optical video backhaul technology is mainly GPON.

37. Huawei's all-optical video backhaul technology is mainly GPON.

38. Huawei all-optical video backhaul network equipment includes OLT, P series ONU and T series ONU.

39. Huawei's power distribution network ONU does not support the function of preventing illegal access of terminals.

40. The MA5621 device is an industrial-grade device developed by Huawei for the energy industry. The device has 4kv lightning protection capability.
