800 Megabyte-per-second Fiber Creates New High Speed

Networking Opportunities

Geneva, Switzerland - April 21, 2000:

GENROCO, Inc. (GEN-ROCO) (OTC Bulletin Board: "GRCI"), a Wisconsin-based provider of high performance storage area network (SAN) hardware and software, and CERN, the European Center for High Energy Physics Research here, demonstrated the world's first implementation of the 800 megabyte per second Gigabyte System Network (GSN) with an optical interface.

"Having optical GSN is important not only for large GSN users, such as CERN, but also for smaller network installations that can not manage the burdens of copper," said Arie van Praag of CERN. "This demonstration proves that GSN works well over optical fiber, opening the doors for more mainstream GSN installations."

Until today, only expensive copper GSN cabling has been available which, in addition to being bulky, is limited to carrying data a maximum of 40 meters. The new, compact optical fiber nearly doubles the distances at one quarter of the cost. Furthermore, optical fiber is known for its lack of emissions, flexibility, ease-of-use, and compatibility with most computer network configurations. The demonstration employed Siemens Paroli optical modules between two GENROCO TURBOfibre(R) TBH-864 GSN bridges, running data transfers error free for several days.

The demonstration is part of a joint venture between CERN and GENROCO for creating leading edge network technology. GENROCO recently announced the TURBOstor(R) Gigabit Ethernet (GigE) to Fibre Channel (FC) bridging and routing switch, which utilized developments that came out of the collaboration last year. The two organizations are currently working on bridging GSN and FC to OC48 in order to create wide area SANs.
