Passive Optical LAN (POL) is an all-optical enterprise networking solution comprising Optical Line Terminals (OLT) and Optical Network Units (ONU). In office scenarios, Huawei’s Campus OptiX POL solution allows flexibility in deployment. Official HCSA-Sales-Transmission & Access documents confirm that OLTs and ONUs can be sold independently based on customer needs, such as upgrading existing infrastructure or deploying specific components in a phased approach. For example, an office might procure an OLT to centralize management while adding ONUs later to expand coverage. This modularity supports tailored solutions, making the statement TRUE.
