Things You Must Know About Gigabit Ethernet
1. Understanding Gigabit Ethernet
Today's network managers know that modern demands on a network by its users can shrink
bandwidth dramatically. Faster computers, increased network resources and greater access to the
Internet can create an unbearable strain on networks with lowered bandwidth resources.

- Page 1 Things You Must Know About Gigabit Ethernet 1. Understanding Gigabit Ethernet Today’s network managers know that modern demands on a network by its users can shrink bandwidth dramatically. Faster computers, increased network resources and greater access to the Internet can create an unbearable strain on networks with lowered bandwidth resources.
- Page 2 It used to be hard to believe that any network would require more than 10Mbit throughput. The capacity of a 10Mbit network long outpaced the capacity of most computers and applications. However, with today’s powerful computers, applications and peripherals, we know how quickly the 10Mbit bandwidth is filled up.
- Page 3 Upgrading your network to Gigabit may be the logical choice, but there is still a choice to make regarding the types of Gigabit. Several cabling options are available. 1000BaseT Copper Gigabit over copper may be the easiest, most cost-effective way to achieve Gigabit speeds. It utilizes Category 5 UTP (Unshielded Twisted Pair), or better, cabling, but requires that all 4 wire pairs be used.
- Page 4 issues that arise with Gigabit over copper: Attenuation—Signal loss of the cabling from the transmitter to the receiver. In order to maintain the 100m distance, attenuation increases with frequency; therefore, all 4 pairs are used to maintain a low frequency, thereby keeping attenuation at an acceptable level. Echo—An unwanted signal generated where both the transmit and receive signal occupy the same wire pair.
- Page 5 1000BaseSX Fiber One form of Gigabit over fiber is the 1000BaseSX specification, which employs short-wave light lengths to transmit data. It uses 62.5-micron multimode fiber for operation at 160-200MHz. It has a range of 2 to 275 meters (ISO/IEC 11801 building wiring standard). 1000BaseSX also operates using 50-micron multimode fiber for operation at 400-500MHz and has a range of 2 to 550 meters (ANSI Fibre Channel specification).
- Page 6 Physical Layer chip sets. Some companies might not support Broadcom PHYs because of this (namely, Intel). Asante still supports use of these early Broadcom PHYs, since you can work around the incompatibility by turning off the IEEE 802.3 compatibility in the driver of your Gigabit Ethernet network card.
- Page 7 4. Utilizing Multimedia Features Now that your network will have such increased bandwidth, the next question becomes how to manage a network’s higher priority traffic. Not every user requires sophisticated applications or runs mission-critical programs, nor do they need the highest speed connections to the Internet. Quality of Service Quality of Service (QoS) refers to a network’s ability to provide improved and consistent services, helping to manage network congestion and ensuring that throughput is maintained, even under...
