Observer nTAP 40Gb Optical

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

  • Copies traffic from one full-duplex optical link to one optical monitoring device
  • Connects to the full-duplex link under test and an analyzer equipped with a dual-receive capture card

Install Observer nTAPs on 1, 10, or 40 Gb single or multi-mode optical links. Or select our newest offering, the Observer High-Density Optical nTAP (HDOT) to mix and match these network speeds or 100 Gb in any combination across 24 modules in a 1U rack.

Use optical nTAPs to send identical copies of critical traffic to network analyzers, remote monitoring appliances, forensics tools, and similar devices capable of supporting dual, non-aggregated data streams. For further flexibility, Observer Copper-to-Optical and Optical-to-Copper Conversion nTAPs are available.

Which nTAP do I need? Tap vs Span

Place a One-Channel 40 Gb Optical nTAP between two devices of interest on a full-duplex optical link. Then attach an optical monitoring device to the nTAP. To successfully analyze the full-duplex link, the monitoring device must be equipped with a dual-receive capture card.
