Spirent adds 40G/100G test capabilities
-- Test & Measurement World, 10/1/2009 2:00:00 AM
Spirent Communications has added a 40/100-Gbps module to its TestCenter chassis-based network tester. The HyperMetrix 40/100 Gigabit Ethernet module uses two TestCenter slots, and it accepts a CFP optical transceiver module as its network interface.
Like other HyperMetrix modules, the 40G/100G module provides protocol testing for layers 2 through 7, and this module also adds testing for layer 1, the physical layer. At layer 1, the module provides lane-skew measurements between the lanes of the optical interface (a 40-Gbps link contains ten 10-Gbps lanes and a 100-Gbps link contains ten 10-Gbps lanes).
You can test a network element with the HyperMetrix module by adding skew to the lanes to find where a link is lost. The module can generate PRBS test patterns for testing bit-error rate on an optical link.
Above the physical layer, the HyperMetrix can generate and analyze layer 2 Ethernet traffic and layer 3 (Internet Protocol) traffic. At the upper layers, it can test HTTP and FTP traffic as well as streaming audio and video with QoE video metrics.
You can run tests through a Windows-based application, and you also can automate your tests through a Tcl scripting interface.
