Black Box LGB5124A-R2 24-Port Gigabit Managed Ethernet SFP Fiber Switch

This advanced, fully-manageable Layer 2 switch gives you networking versatility. It features 24 high-speed fiber ports: (20) 100-/1000-Mbps SFP fiber ports and (4) dual-media 100-/1000-Mbps SFP/twisted-pair ports. This all fiber switch gives you the flexibility to select a variety of ranges with SFP transceivers. This switch offers advanced switching and security features normally found in more expensive switches. You'll get extensive management capabilities, greater bandwidth control and QoS for switching in VoIP and other real-time, high-performance applications.

 To provide more bandwidth to a specific application or segment, combine ports using the switch's 802.3ad Link Aggregate Control Protocol (LACP) capabilities. With this bandwidth aggregation feature, the combined ports create a multilink trunk for load sharing. The switch supports 12 groups with 8 ports per group.
