[. . . ] Network Aggregation Plan 2-3 NETWORK PLANNING Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, and a 1000BASE-LX (SMF) link can run up to 5 km. This allows the Gigabit Ethernet Switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN. A 1000BASE-SX SFP can be used for a high-speed connection between floors in the same building, and a 1000BASE-LX SFP can be used to connect to other buildings in a campus setting. The figure below illustrates this switch connecting multiple segments with fiber cable.

Figure 2-3. Remote Connection with Fiber Cable 2-4 APPLICATION EXAMPLES Making VLAN Connections This switch supports VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment. VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs. Untagged VLANs can be used for small networks attached to a single switch. However, tagged VLANs should be used for larger networks, and all the VLANs assigned to the inter-switch links. The switch also supports multiple spanning trees which allow VLANs groups to maintain a more stable path between all VLAN members. This can reduce the overall amount of protocol traffic crossing the network, and provide a shorter reconfiguration time when any link in the spanning tree fails.

Making VLAN Connections Note: When connecting to a switch that does not support IEEE 802. 1Q VLAN tags, use untagged ports. 2-5 NETWORK PLANNING Application Notes 1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub. As a general rule the length of fiber optic cable for a single switched link should not exceed 550 m (1805 ft) for multimode fiber or 5 km (16404 ft) for single-mode fiber. For longer connections, you can use a 1000BASE-ZX SFP transceiver, which supports runs of up to 100 kilometers. However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment. 2-6 CHAPTER 3 INSTALLING THE SWITCH Selecting a Site TigerSwitch 10/100/1000 units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location. [. . . ] The successor IEEE 802. 3 standard provides for integration into the OSI model and extends the physical layer and media with repeaters and implementations that operate on fiber, thin coax and twisted-pair cable.
