10/100 Copper Ethernet Aggregation Tap

With 1 network Connection and 2 Monitor Connections

24x7 Real-time Secure Access and Dual monitoring with 1 device

24x7 Real-time Secure Access and Dual monitoring with 1 device

USRobotics new 10/100 Copper Aggregation Tap provides a reliable solution for 24x7 capturing of full-duplex Ethernet links in a combined single stream of data on a network link. This tap faultlessly combines and processes both the TX and RX streams of data into a single data stream that allows any connected monitoring device (analyzer, IDS, probe) to receive a full-duplex stream of data with only one NIC. With two monitor ports, the combined stream of data can be sent to two separate network tools for simultaneous monitoring and analyzing. In addition redundant power solutions ensure network up-time even when the main power source is unavailable making this aggregating tap the ideal solution for secure, stable network traffic.


Monitoring & Analysis

  • Captures and combines traffic from both sides of the network conversation and delivers a copy of the combined traffic to the analysis tool(s)
  • Two monitor ports allow two devices to simultaneously monitor the same link
  • 100% visibility into the network - including VLAN tags
  • View all traffic on both sides of full duplex links
  • View Layer 1 and 2 errors such as runts and CRC errors
  • Full duplex negotiation
  • Reduces degradation of switch performance due to port mirroring
  • Best method to measure network link's performance

Network Stability

  • Maintain network stability with a memory buffer that manages traffic bursts preventing data overloads and dropped packets
  • Ideal for 24x7 permanent access - eliminating the need to connect tools each time a link needs to be monitored
  • Non-intrusive way to connect a network tool
  • Fault-tolerant
  • Non-directional totally passive inline tap
  • Minimize traffic delay through the tap


  • Invisible on the network
  • No single point of failure*

Simple installation

  • Plug and play
  • Comes with convenient built-in rackmount or use an optional 1U rack mount kit for up to 3 devices.
  • 10/100 BaseT compatible

Reliable Power

  • Redundant power supply insures seamless monitoring even if the main power source is unavailable
  • In the event of a power failure, the tap will continue to pass network traffic uninterrupted
  • Supports Power over Ethernet (PoE) on pairs 4, 5, 7 and 8
