1. The L could just as well stand for long distance 1000BASE LX supports longer distances than shorter wavelength standards up to 550 meters 1804 ft full duplex over multimode fiber and up to 5000 meters 16 404 ft full duplex over single mode fiber At half duplex 1000BASE LX goes up to 316 meters 1000BASE SX The S in 1000BASE SX stands for short 1000BASE SX uses short wavelength lasers operating in the 770 to 860 nanometer range to transmit data over fiber It has the advantage of being less expensive than 1000BASE LX but operates only over multimode fiber at distances up to 316 meters half duplex or 550 meters full duplex 1000BASE CX The C stands for copper and 1000BASE CX operates over copper twinax cable at distances of up to 25 meters This standard never caught on largely because of the short distance it covers In addition twinax cable is only slightly less expensive than fiber optic cable and is difficult to install Gigabit over CAT5 1000BASE T The relatively new IEEE 802 3ab standard approved in June 1999 defines running Gigabit Ethernet over Category 5 copper wiring The importance of this is that now you can run IEEE compliant Gigabit Ethernet over existing copper cable at distances of up to 100 meters This results in a significant savings over the cost of fiber because not only is copper twisted pair less expensive to install it s also often already installed2. The 802 3ab specification works with any existing Category 5 cable as long as it s been tested and certified However Gigabit Ethernet uses all four twisted pairs within the cable unlike 10BASE T and 100BASE TX which only use two of the four pairs 1000BASE T works by transmitting 250 Mbps over each of the four pairs in 4 pair Category 5 UTP cable And although the 100 meter maximum defined by 802 3ab might not sound like much compared to fiber it s the same distance limit as Fast Ethernet on Category 5 cabling But what can do with it At a billion bits per second Gigabit Ethernet has the potential to blow through virtually any bandwidth bottleneck continued on page 6 lt gt BLACK BOX NETWORK SERVICES Technically Speaking continued from page 5 above the LAN based hubs The Gigabit per second speed opens Gigabit Ethernet makes it possible to blast packets through a fat pipe where all LAN traffic can flow freely even the most congested links Gigabit Ethernet can be used Gigabit over copper will probably find its place in server to build enormous switched networks and move traffic through connections and intrabuilding backbones areas that are still them at blinding speed It s a perfect choice for delay sensitive largely the domain of Category 5 cabling Instead of adding applications such as voice and video expensive fiber to create a Gigabit Ethernet backbone companies L r Gigabit Ethernet makes sense when y

4. BASE T is interoperable with 10BASE T through the use of 10 100 Mbps devices Plus the cost of adding these 100 Mbps network islands to your Ethernet is minimal especially when compared to the cost of a full blown network upgrade How do add 100BASE T to my Ethernet LAN You can add a 100BASE T island to your 10BASE T network with a 10 100 Mbps Ethernet hub or a 10 100 Mbps Ethernet switch If you use a hub to incorporate Fast Ethernet into your network the hub will simply provide a link between the 10 Mbps network and the 100 Mbps network islands However hubs have no addressing features and do not differentiate among destinations for information packets In this case the network is simply extended and you may experience inefficiencies in data transfer between the two sides Switches are usually a far more effective choice for building Fast Ethernet islands because they have addressing features that retime filter forward and drop network packets When you use switches your network is actually segmented into separate collision domains The rules of the game There are a few rules to remember when you re incorporating Fast Ethernet into existing 10 Mbps networks 1 Make sure you use the same 100BASE T standard on your network For example if you re connecting a PC with a 100BASE TX NIC to a hub the hub must also support 100BASE TX Also some implementations of 100BASE T aren t interoperable For example 100BASE TX won
5. Category 3 4 and 5 cable and functions quite well in noisy environments giving the standard an element of flexibility in UTP Fast Ethernet applications not shared by 100BASE TX or 100BASE FX The distance limitations for the 100BASE T4 standard is the same as 100BASE TX 100 m 328 ft Why replace 10BASE T Ethernet Fast Ethernet hasn t come close to completely replacing 10BASE T Ethernet but in some cases 10BASE T simply can t keep up with new multimedia applications and large files that have become a large part of many corporate networks continued on page 4 blackbox com lt gt BLACK BOX NETWORK SERVICES 9 25 2012 10858 724 746 5500 blackbox com Technically Speaking continued from page 3 And with increased network density data throughput suffers greatly Some earlier solutions to lagging network throughput looked promising For example using full duplex switches on a 10 Mbps network known as switched Ethernet effectively increased data rates to 20 Mbps However many high bandwidth applica tions and large data files have since outgrown switched Ethernet The solution In light of these issues adding 100 Mbps network segments or islands to existing 10BASE T networks has become a popular method of improving network throughput and some features of Fast Ethernet make this option an attractive one First because the data is constructed the same way for both 10BASE T and 100BASE T 100

8. at exactly is Gigabit Ethernet anyway and how can you use it First of all Gigabit Ethernet is a true Ethernet standard and is compatible with both 10 and 100 Mbps Ethernet Because it uses the same frame formats and flow control methods as earlier Ethernet versions networks readily recognize it The primary difference is that Gigabit Ethernet almost always runs in full duplex mode rather than the half duplex mode commonly found in 10 and 100 Mbps Ethernet Full duplex means a lot more bandwidth A single Gigabit Ethernet switch port can handle traffic from as many as 20 half duplex fast Ethernet links or up to 200 half duplex Ethernet ports When Gigabit Ethernet first appeared fiber was crucial to running Gigabit Ethernet effectively Since then the IEEE 802 3ab standard for Gigabit over Category 5 cable has been approved enabling short stretches of Gigabit speed over existing copper cable The First Gigabit Standards 1000BASE X 1000BASE X refers collectively to the 1000BASE LX 1000BASE SX and 1000BASE CX Gigabit Ethernet standards ratified in 1998 1000BASE LX and 1000BASE SX are fiber standards 1000BASE CX is an early copper standard that enabled Gigabit Ethernet to run over twinax cable 1000BASE LX The L stands for long and it uses long wavelength lasers operating in the range of 1270 to 1355 nanometers to transmit data over fiber optic cable 1000BASE LX supports both single mode and multimode fiber
