Single-mode fiber model transmits up to 15 kilometers (9.3 miles). With BLACK BOX(R) Managed Express Switches, Ethernet switching is more versatile--and more affordable--than ever! They combine the versatility of Ethernet and Fast Ethernet autonegotiating ports with the speed and distance of a 100-Mbps or 1000-Mbps fiber connection--and they're priced just right! Add manageability and you have the powerhouse switches that drive your enterprise network. These switches are fully manageable and include support for SNMP and RMON. You can manage them out-of-band through the RS-232 console port or across the network using any Web browser. Managed Express Ethernet Switches feature 802.3p Priority Queuing for quality of service. This enables you to give different priorities to different types of traffic. The 802.1Q Tagged VLAN support improves traffic management, network segmentation, and network security. IGMP snooping and Multicast Filtering enables the switches to support IP multicast traffic and video multicasting or broadcasting. The switches also support switch-to-switch trunking, port-mirroring and monitoring for traffic snooping. The switches' true nonblocking architecture means you get wire-speed packet switching, and their packet-forwarding capabilities boost your network's performance. The 802.3x flow control and backpressure prevents overflow of data frames for better traffic management during times of network congestion. Front-panel LEDs provide at-a-glance status checks for each port. Like all BLACK BOX(R) Switches, Managed Express Ethernet Switches are built tough. They're housed in a lightweight, high-strength, metal case. The RJ-45 ports feature shielded housing. Fixed-Port Managed Express Ethernet Switches Each fixed-port switch comes with seven autonegotiating RJ-45 ports for 10-Mbps Ethernet or 100-Mbps Fast Ethernet links, plus one multimode or single-mode 100-Mbps fiber port. The RJ-45 ports are perfect for short-distance networking between offices, workgroups, and buildings. The fiber port enables you to communicate over a longer distance or through harsh industrial settings. For fiber connections up to 2 kilometers (1.2 miles), choose the LB9030A or LB9031A. For longer distances, the LB9032A transmits or receives up to 20 kilometers (12.4 miles) over single-mode SC fiber.
