OverviewBD-S2228/S2228F/S2228PoE is a modularized hi-performance workgroup-level or enterprise-scale switch,with 24 Fast Ethernet ports(24 100M SFP slots for S2228F),plus maximum 4 gigabit ports. BD-S2228/S2228F/S2228PoE can connect all (Fast) Ethernet devices so that your investment is protected.The hi-speed connection it provides among workgroups can boost the capability of server clusters, andsolves the bottleneck caused by increasing users and limited bandwidth, making network resourcesmore readily available to you. More importantly, all of the advantages are brought to you by BAUDCOMat low costs and with easy maintenanceApplication� Hi-performance, network manageable inter-workgroup or enterprise-edge switchingFeaturesPerformance� 36 Gbps switch fabric, hardware routing, wire-speed L2 forwarding rate: 9.5 Mpps� 80-km transfer by Gigabit optical fiber, direct connection to WANSecurity and reliability� IEEE 802.1x and other methods for user authentication� Powerful ACL supports L2-L7 data filtering� QinQ support.

FAQ
Q: Can the 24port SFP ethernet switch support SFP DOM/DDM function(power monitoring etc)?
A: The SFP switch have two kinds SFP ports,one is 100M SFP (24ports) which can not support DOM/DDM function,another is 1000M GSFP (2ports) which can support DOM/DDM function.
Q: Can the SFP ethernet switch support QinQ function?
A: The SFP switch support QinQ VLAN function.
