Optical to Copper Conversion nTAP

Copy traffic from one full-duplex optical link to one copper monitoring device

  • Copies traffic from one full-duplex optical link to one copper monitoring device
  • Connects to the full-duplex link under test and an analyzer equipped with a dual-receive capture card
  • Compatible with network analyzers, security monitoring devices, forensics tools, remote monitoring appliances, and RMON probes

Install Observer Conversion nTAPs on 10 Mb, 100 Mb, or 1 Gb links for quick, anytime access to network traffic. When analyzers and similar monitoring devices communicate over different topologies than the network, Optical-to-Copper or Copper-to-Optical nTAPs bridge the gap. Conversion nTAPs make copies of network data, sending one back to the network and the other out for analysis.

For single-receive devices, Observer Aggregator Conversion nTAPs merge full-duplex links into single streams for transmission to up to two single-receive analysis devices. Industry-leading buffer sizes offer less likelihood of lost packets than SPAN ports to ensure critical traffic reaches analyzers, remote monitoring appliances, and forensics tools.

nTAPs are passive, full-duplex devices, offering complete visibility to monitoring devices regardless of traffic level. They work with the leading management tools for quick and easy deployment. nTAPs are transparent for monitoring critical links, and provide continuous network data flow even if power fails. nTAPs are scalable, modularized, space efficient, and economical.

Which nTAP do I need? Tap vs Span

Place an Optical to Copper nTAP between two devices of interest on a 1Gbps full-duplex optical link. Then attach a 1Gb copper monitoring device to the nTAP. To successfuly analyze the full-duplex output from the TAP, the monitoring device must be equipped with a dual-receive capture card.
