Field tool tests carrier Ethernet networks
-- Test & Measurement World, 9/1/2008
The battery-powered, handheld Unipro GbE from Trend Communications is intended for the roll-out of metropolitan, access, and carrier Ethernet networks. The instrument lets you test and verify any Ethernet service from the physical layer to the IP layer, and it incorporates traffic generation, filtering and analysis, IP ping, and trace route.
The Trend Unipro GbE executes RFC 2544 tests and verifies connectivity, frame transportability, and throughput. Advanced tests include verification of auto-negotiation when connecting nodes, VLAN configuration and routing, admission control and congestion avoidance mechanisms, quality of service provided by the network, and service-level agreements.
The tester has two electrical RJ-45 ports and two optical SFP GBICs, which simplify bidirectional traffic monitoring. When the Unipro GbE is used in through mode, it simultaneously works with two transmitters and two receivers, enabling intrusive monitoring. This mode is also useful for general monitoring when no splitter is available.
