Solutions
We provide professional optical fiber communication solutions tailored to different industries and application scenarios.
FTTN (Fiber to the Node)
The FTTN (Fiber to the Node) solution involves laying optical fibers to node cabinets several miles away from users, then transmitting network signals to user terminals via traditional copper cables. It is an ideal choice for meeting the broadband upgrade needs of urban areas or communities, and is suitable for access requirements in small and medium-sized regions.
