The PTN (Packet Transport Network) product series offers a comprehensive range of solutions designed to meet the demands of modern transport networks. Developed with a switching capacity ranging from 3G to 960G, these products cover the entire network section application, from the core to the access layer. With the integration of native MPLS-TP (Multi-Protocol Label Switching - Transport Profile) technologies, the PTN products are fully compliant with the latest standards defined by IETF and ITU-T, making them an ideal choice for networks characterized by explosive packet traffic, flexible traffic scheduling, and the high reliability traditionally associated with SDH (Synchronous Digital Hierarchy) networks.
