Gigabit Ethernet is the IEEE 802.3 Ethernet standard extension, the transmission speed of 1000 megabits per second (ie 1Gbps). Initially used in large campus network, can make existing 10Mbps Ethernet and 100Mbps Fast Ethernet link. It can replace the 100Mbps FDDI network, ATM technology is a strong opponent. Between switches support Gigabit Ethernet, full duplex switch with terminal connection between the support half-duplex shared network connection, using repeaters and CSMA / CD collision detection mechanism.
Special A d ve rtising Section Gigabit Ethernet: How Far Will It Go? By Julien Gorbach Is The Distance Issue A MAN-Made Problem? For users looking to use Gigabit Ethernet beyond the LAN, there’s good news and bad news. The good news is that the technology says you can. The bad news is that the specification says you can’t. Gigabit Ethernet products just started to seriously emerge this year and almost all were designed for LAN- based GbE use. But a variety of vendors have started toying with Metropolitan Area Network (MAN) and even some WAN usage. For businesses where it makes sense, the distance limits are little more than irrelevant technicalities. The possibility of Gigabit Ethernet extending beyond the 5-kilometer IEEE limit puts it into direct competition with ATM for those lucrative MAN implementations. At the heart of this “MANly” distance issue are the precise technical means by which the data is sent through the fiber. Fast Ethernet uses LED (Light Emitting Diode) to send messages within its pipe, while Gigabit Ethernet opts for laser because only laser can flash fast enough for Gigabit speed. IEEE has therefore established a new set of standards, specify- ing the distance limitations for transmission ge Continued on pa GE 3 October 1,1998 Network Computing GE 1 Special A d ve r tising Section along single mode and multimode fiber.
