Passive monitoring access for 100% visibility

Get total traffic visibility for 10/100/1000 monitoring and security devices by placing Net Optics 10/100/1000BaseT Taps on critical network links. 10/100/1000BaseT Taps support passive monitoring of 10/100/1000 links at 10, 100, or 1000 Mbps. This Tap is ideal when a passive Tap is required for use with a variety of copper monitoring devices.

For superior reliability, the 10/100/1000BaseT Tap features Link Fault Detect (LFD), which gives the devices connected to the Tap critical information about link status. If either side of the bi-directional link fails, the Tap immediately communicates the fault to both devices, reducing the time required to activate a redundant path.

Transparent Access

The 10/100/1000BaseT Taps establish permanent passive access ports without introducing a point of failure or disturbing other network connections. The 10/100/1000BaseT Tap either auto-negotiates communication or uses an external DIP switch to set fixed speed and duplexing parameters. These passive Taps deliver full-duplex monitoring with zero impact on network traffic around the clock.

Security and Visibility

Without an IP address, monitoring devices are isolated from the network, dramatically reducing their exposure to attacks. However, the monitoring device connected to the Tap still sees all full-duplex traffic as if it were in-line, including Layer 1 and Layer 2 errors.

Simply Plug It In

Full-duplex monitoring is a snap when each side of the signal is sent to a separate NIC on the monitoring device. All network and monitoring cables necessary for plug-and-play deployment are included with the Tap.


For extra up time protection, Net Optics 10/100/1000BaseT Taps offer redundant power connections. Should the primary power source fail, the Tap automatically switches to the backup power source. Power LEDs on the front of the Tap indicate the current power source.
