Bill: Careful here. The gigabit Ethernet standard carries 1,000 Mb/sec over 4 CAT5 copper pairs (250Mb/sec per pair) at 100m. This is about as far as copper will go, i.e. you will not see 10 Gigabits/sec over copper. Note also that the BRCM chip is based on an open IEEE standard (802.3ab) and INTC/LEVL, LU and perhaps CNXT will soon have similar chips. In fact, BRCM has announced this chip at 2 other times (in October and then in January) even though it was not working in either case. Maybe the third time will be a charm.

Gigabit Ethernet: The Difference Is In the Details (excerpt from article link below) Sizing up gigabit Ethernet is all about coming to terms with the IEEE spec - and learning how this bit-blaster can actually slow down corporate networks Gigabit Ethernet? Heed the hype and the high-speed technology sounds like the answer to most net managers' prayers. Simple and familiar--and a pipe fat enough to handle any app: switched workgroup, corporate intranet, real-time multimedia, whatever. Filter out the industry buzz, however, and gigabit starts sounding more like gigabut. True, the technology looks a lot like the Ethernet and fast Ethernet corporate networkers know and love. And at 1 billion bits per second, it has the potential to blow through virtually any bandwidth bottleneck. The rest is here: data.com

Bill, for those who may not be aware, that BRCM product is designed for LAN use, up to distances of 100 meters using Category 5 Cabling. It's based on the IEEE 802.ab spec, which is different from the 802.3z GE specification which is only good for pushing Cat 5 copper up to 25 meters. The BRCM feat is truly noteworthy, and incredibly breakaway. It's good for a four fold increase in distance when using Cat 5. Given the hostilities that exist in that region, it's really saying something, but who is ready to use GE at the desktop at this time, save for some CADD stations and modeling machines? Up until now, GE has been a protocol for server farms, storage area nets, risers and campus backbones, but it's not going to be an item on many desktops for a long time to come, where most office automation suites are concerned. Specialized apps only, for the time being. FWIW, Frank Coluccio

Bill: Regarding BRCM's Interop demonstration of Gigabit Ethernet over copper, apparently the third time was not a charm. According to what I heard, only one of the 4 transceivers worked and at a distance of only 50m. BRCM is a fine company, but they need to develop a more conservative and businesslike approach towards issuing press releases. Otherwise, they are leaving themselves open to lawsuits of all types if the slightest disappointment ever occurs. Best regards, Bernard Levy
