The Fast Ethernet Alliance, formed in August to try to persuade the US Institute of Electrical & Electronic Engineers to adopt Union City, California-based Grand Junction Networks Inc’s proposal for doing 100Mbps Ethernet, has published its first interoperability specification. The 100Base-X specification was announced in July and was developed by members of the group, including 3Com Corp, Grand Junction, Intel Corp, National Semiconductor Corp, Sun Microsystems Computer Corp, and SynOptics Communications Inc. It will be presented for consideration to the IEEE this month, but the alliance says that it is being made available free of charge to anyone that is interested.
