Which of the following statements are reasonable for ONU deployment in POL scenarios? (Multiple choice)

• A.When deploying ONU, the later expansion needs should also be considered, especially when using information boxes to install ONUs, sufficient space for equipment installation should be reserved for future expansions.
• B.The security of the ONU needs to be considered during deployment, especially the risk of equipment heat dissipation and human damage.
• C.The later maintainability should be fully considered when deploying the ONU, and the location where the ONU is installed should be convenient for maintenance.
• D.The deployment of ONU should also consider aesthetics. If customers have high requirements for aesthetics, installation methods such as under-desk installation and information box embedded in the wall can be optional options.
• E.The installation location and method of the ONU need to consider multiple factors, and choose a more balanced solution among the factors.
• F.The closer the ONU is deployed to the information node, the better. The closer it is to the information node, the better the access features and advantages of the POL. Therefore, for the large-bay office scenario, the ONU is preferentially deployed on the desk surface or below.
