Product Classic Network Applications

  Application 1: 5G Semi-Active Solution This solution requires the deployment of 5G semi-active equipment on the DU side and AAU side in a DU-AAU scenario. The semi-active equipment between the DU and AAU requires only two core fibers, providing one main and one backup line with 1+1 protection. The eCPRI optical interface of the DU and AAU uses the 25G colored light module.
Application 2: Passive Solution The passive solution requires deploying passive optical fiber expansion equipment between the BBU/DU pool and the RRU/AAU. Only one pair of fibers is needed between the passive optical fiber expansion equipment, and the CPRI interface of the RRU/AAU and BBU/DU uses the optical fiber expansion SFP colored light module.  
Application 3: Active Solution The active solution requires deploying active optical fiber expansion equipment between the BBU/DU pool and the RRU/AAU. Only one pair of fibers is needed between the active optical fiber expansion equipment. There is no need to change the form of the original BBU/DU equipment and RRU/AAU equipment, and it supports mixed transmission of various types of services in a plug-and-play manner.  
Application 4: OLP Optical Protection Scheme The OLP optical protection scheme is used to protect the optical cable line. It requires adding OLP optical protection equipment at both ends of the optical transmission equipment while providing main and backup different routing lines. It can be used with dispersion compensation modules and amplifier modules, supporting dual-fiber bidirectional and single-fiber bidirectional transparent transmission, with standby fiber monitoring function, and switching time less than 20ms in case of failure, achieving fast optical line switching.  
Application 5: OBP Optical Bypass Protection Scheme The OBP optical bypass protection scheme is used to bypass a single site or single device failure, maintaining the connectivity of the entire network. It supports the heartbeat bypass function and amplifier bypass function, with a bypass time of less than 25ms in case of failure, achieving quick bypass during device failure or power outage.
