                                         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
