II. Core Product Applications
This product focuses on rate bridging between 100GE and 25GE ports, enabling interconnection of different rate ports without modifying existing equipment. It is widely used in three core scenarios, balancing practicality and economy:
-
Base Station Scenario: Compatible with Nokia AirScale base stations, converting the 100GE QSFP28 ports built into the base stations to 25GE SFP28 ports, connecting to 25G optical modules or peer 25GE transmission equipment. It helps with high-speed transmission of base station signals, meets the needs of 5G base station expansion and upgrading, and greatly reduces upgrade costs without replacing core base station equipment.
-
Data Center Scenario: Builds a rate bridge between 100GE core switches and 25GE servers/storage equipment, solving the problem of incompatible interfaces of different rate equipment, optimizing the data center network architecture, and improving data transmission efficiency. It is suitable for expansion and equipment update scenarios of small and medium-sized data centers, protecting existing 25G equipment investment.
-
Transmission Network Scenario: Used for interconnection between 100G transmission links and 25G transmission links, adapting to the rate connection of backbone networks and metropolitan area networks. It can realize seamless connection of different rate networks without re-laying links, reducing network upgrade and maintenance costs, and ensuring the stability and compatibility of transmission links.
