Huawei OLT aggregates various terminals and provides high-density ports, which can reduce network nodes, sites, and equipment rooms. This simplifies network architecture, reduces device investment and O&M costs, and improves network deployment efficiency. PON/10G PON/GE/10GE in the same platform can help operators carry out smooth network evolution and protect their investments. Building a network that supports unified access for home, enterprise, and mobile back-haul services can reduce network construction costs, enrich the user experience, increase end-user loyalty, and improve the average revenue per user (ARPU). Huawei OLT is widely deployed around the world, serving more than 85 operators.
