Finisar Introduces 2nd Generation PCI Express Analyzer

INTEL DEVELOPER FORUM -- Finisar Corporation (NASDAQ: FNSR), a leading provider of network monitoring and analysis solutions announced today the availability of a 16-bit bus analyzer pod for its industry leading RX-252 analyzer. The RX-252 analyzer is a product from Finisar's recent acquisition of Data Transit Corporation in August 2004. The new x16 pod is capable of capturing traffic from a 16 wide lane. This new version analyzer has advanced features, including more memory channels and cross-sequence triggering. It is designed specifically for high-speed, multi-lane, multiple protocol serial buses such as the PCI Express x16 and Wide Port SAS also introduced earlier this year.

"Finisar consistently pushes the envelope with devices that press the limits of today's PCI Express equipment," said Bob Otis, Vice President of Engineering, Finisar Network Tools. "The scalable RX-252 Series is a system that delivers the test capabilities required by today's PCI Express vendors and provides test solutions in lockstep with performance demands."

The RX-252 is an extremely high-performance analyzer with 252 memory channels. The 252 memory channels enable the analyzer and the control PC to keep up with the significantly greater data throughput found in buses like Wide Port SAS and PCI Express x16. To the end user, this means all data traffic is captured and saved, eliminating the possibility of lost or dropped packets.

The x16 pod and RX-252 analyzer can capture traffic in one direction but can also be configured with another x16 pod and RX-252 analyzer to capture traffic in both directions. Protocol information from both directions can be displayed together simultaneously on a control PC.

Finisar is showcasing the Bus Doctor RX-252 Analyzer at Booth 1039 at the Intel Developer Forum September 7th through the 9th in San Francisco.
