Exfo Electro-Optical Engineering Inc. offers the IQS-8510G Packet Blazer for testing 10-Gigabit Ethernet interfaces in optical networks. Housed inside the companys rack-mounted IQS-500 Intelligent Test System, it is designed for manufacturing environments, system verification and laboratory applications. It can characterize local and/or wide-area network physical interfaces with the same test module at all available wavelengths. Patent-pending EtherBert technology provides bit-error-rate testing of Ethernet interfaces. The module tests Ethernet connectivity in its native format for LAN-to-LAN services delivered via ATM, frame relay, next-generation SONET/SDH, switched Ethernet, VLANs, dark fiber and WDM.
