ETHERNET nTAP PRODUCT FAMILY Monitor mission-critical network links transparently and economically Network Instruments nTAPs ensure complete visibility into your high-speed network links without compromising network performance or risking costly downtime. Regardless of your link type, device type or analysis tool, there is an nTAP solution that fits your needs and your budget. nTAPs are ideal for enterprise organizations using analysis tools such as network analyzers, protocol analyzers, intrusion detection or prevention systems, forensic appliances, remote monitoring appliances, RMON probes, and security monitoring devices. The nTAP product family offers flexibility with a variety of configurations for both copper and optical fiber. The security and convenience of nTAPs makes them preferable to inline connections for network analysis and intrusion detection applications. Because an nTAP has no address on the network, it cannot be the target of a hack or virus attack. nTAPs are economical to install, allowing you to leave them permanently deployed. A permanent connection allows you to connect and disconnect the monitoring or analysis device from the nTAP without having to break the full-duplex signal. TAP into Network Performance and Visibility Error View One of the key advantages an nTAP has over a switch port mirror is its ability to provide access to all network traffic, including errors found in the physical layer from both sides of a full-duplex link. Latest Technology By utilizing the latest chipsets, nTAPs offer a more compact design and increased reliability, offering the next generation of passive analysis. Network Transparency nTAPs support redundant failover links on your network. If one side of the link should fail, the nTAP is made transparent so that the other side can take appropriate action such as switching to a redundant link. This provides additional support for managing network connections. Unique Offerings Unlike competitive offerings, the nTAP product family includes an auto-negotiating 10/100/1000 Copper nTAP and a 10/100/1000 Copper to Optical Conversion nTAP for greater flexibility in your current and future needs. Meets International RF Emission Standards nTAPs are certified by both the FCC and CE organizations for worldwide use. For emissions, CE marks and additional compliance information, please visit www.networkinstruments.com. nTAPs for Copper Links nTAPs are available to monitor copper links up to gigabit speed. Conversion nTAPs allow you to analyze copper links through an optical or copper analysis interface.
nTAPs for Optical Fiber Links Optical nTAPs use prisms to split the signal from a full-duplex connection between the network and the analysis device. Optical nTAPs offer a choice of 50/50, 60/40, 70/30, 80/20 and 90/10 signal split ratio, so you can choose how the signal strength will be distributed between the original destination and the analysis port.
Using a SPAN port vs. an nTAP for Gigabit Analysis For network environments that demand full-duplex gigabit analysis now, or in the future, a SPAN port is inadequate. An nTAP can guarantee that your analysis device receives both sides of the full-duplex data stream. An nTAP enables complete visibility into your full-duplex links • Unlike the SPAN port or port mirror mechanisms on a switch, nTAPs cannot drop packets • nTAPs do not affect switch performance • nTAPs assure up to 2000 Mbps of data delivery into the analysis device
