ZTE has established comprehensive end-to-end all-optical network coverage within the realm of optical communications. In the sphere of optical transmission, ZTE has set a global benchmark by achieving single-wave 1Tb/s optical signal transmission utilizing hollow-core fibers. It has also accomplished on-site network testing for 1.6T metropolitan coherent products and introduced the world's inaugural full-frequency OTN (Optical Transport Network), which has been deployed in both pilot and commercial settings.

In the domain of optical access, ZTE has successfully developed a trial commercial prototype for the third-generation time-division coexistence technical solution of 50G PON (Passive Optical Network). Regarding optical terminals, the annual shipment volume of FTTR (Fiber to the Room) solutions has surpassed 10 million units, and ZTE holds the top position globally in terms of PON CPE (Customer Premises Equipment) shipment volume. Furthermore, the company is actively engaged in researching cutting-edge technologies such as 2T+ and CPO (Co-Packaged Optics).
