What Is the Basic Principle of FTT5G?

Hello friend！

FTT is deployed on the base station side and the core network side to form a tunnel. Let the data travel in the tunnel. This feature ensures the information security (encrypted information) of terminal data during transmission between the base station and the core network.

An OLT and an ONT are mainly applied to a 5G access network and are generally deployed on a node between a base station and a core network.

PON is mainly applied to 5G fronthaul networks and uses WDM-PON technology. 

Wavelength Division Multiplexing PON, or WDM-PON, is a non-standard type of passive optical networking, being developed by some companies. The multiple wavelengths of a WDM-PON can be used to separate Optical Network Units (ONUs) into several virtual PONs co-existing on the same physical infrastructure. Alternatively, the wavelengths can be used collectively through statistical multiplexing to provide efficient wavelength utilization and lower delays experienced by the ONUs.
