25 Ports Layer 3 Data Center Switch with 24x 10G SFP+ ports

Lightem LT25-24SFP+ 10 Gigabit data center switch. It provides 24x 10G SFP+ optical ports, 1x 10/100/1000M RJ45 electrical ports. With high bandwidth and low latency, pipe network. It located in density of the next generation of data center and cloud computing network access, can also be used for large Internet cafes, the core of enterprise network, metropolitan area network, or gathering.


  • 480G backplane bandwidth
  • 24 10Gb optical ports, the highest density (1U TOR), meet the demand of high-density 10G server access.
  • Hardware routing, wire-speed 3rd layer switching packet forwarding rate of 360.092Mpps
  • Able to be managed via Web, SNMP, etc
  • Support XModem protocol, use TFTP/ZMODEM for software upgrading and BootRom upgrading
  • Support SFP+, simultaneously downward compatible XFP
  • Support flexible port configuration
  • Automatically detect and control broadcast storm, support IGMP packets detection, effectively limit the flooding of broadcast packets.
  • Support Ethernet interface taking 1M as the step length for rate limiting
  • Provide DOS, DDOS, spoofing and virus defense
  • Support IEEE802.1x, provide port-based user authentication, network shield, safety control, and policy control technology
  • Restrict the maximum number of hosts connected with the port, multi-binding Ethernet interface , increasing bandwidth and system redundancy
