1 Product Introduction
The RG-SF2920U series switches are simplistic optical switches released by Ruijie Networks for all-optical network
scenarios.
The switches adopt a new hardware architecture design to implement dual-network deployment on one switch, reduce
noise, save energy, and support flexible installation. They are equipped with built-in power supplies and feature reliability
and stability. They are suitable for indoor scenarios.
With Ruijie's modular OS, the RG-SF2920Useries switches support the simplistic optical Ethernet solution, and implement
lifecycle management, security control, plug and play, and intelligent O&M through software-defined networking (SDN).
