10/100/1000 Copper to Optical Conversion nTAP

Copy gigabit traffic from a full-duplex copper link for a copper or optical monitoring device


  • Copies gigabit traffic from a full-duplex copper link for a copper or optical monitoring device
  • Connects to the full-duplex link under test, and a copper or optical analyzer equipped with a dual-receive capture card

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 a 10/100/100 Copper to Optical Conversion nTAP between two devices of interest on a 100 Mbps or 1000 Mbps copper link. Then attach either a copper or optical monitoring device to the nTAP. Only one analyzer connection can be utilized at a time. To successfully analyze the full-duplex link, the monitoring device must be equipped with a dual-receive capture card.
