USROBOTICS USR4503 10/100/1000 Copper Aggregation Tap will tap a single network link and make copies of traffic

USR4503 Gigabit Copper Aggregation Network Tap

10/100/1000 Copper Aggregation Tap with 1 Network Connection and 2 Uni-Directional Monitor Connections

Full Duplex Gigabit Access For Single Interface Monitoring

The USR® 10/100/1000 Copper Aggregation Tap eliminates SPAN port contention, oversubscription, and configuration errors with full duplex monitoring, simple installation, and reliable access to your Gigabit Ethernet segments. This tap faultlessly combines and processes both the TX and RX streams of data into a single data stream allowing any connected monitoring device (analyzer, IDS, probe) to receive a full-duplex stream of data with only one NIC. Improve visibility with two monitor ports sending identical copies to separate network tools for simultaneous monitoring and analyzing. For dual-receive tools, a half-duplex option is available for individual TX and RX streams. Ideal for security applications or anywhere you need non-intrusive dedicated access to your network links for advanced or consolidated monitoring.


Monitoring & Analysis

  • Full duplex monitoring, even with single interface monitoring tools
  • Half duplex monitoring allows two monitoring ports to see full line rate traffic
  • Regeneration to multiple tools provides access to the same links for system redundancy, testing and advanced monitoring applications
  • Improved visibility into the network - including VLAN tags
  • Ideal for Intrusion Detection System (IDS) applications

Network Stability

  • Fault-tolerant
  • Ideal for 24x7 permanent access - Deploy tools or utilize tap ports immediately without network traffic interruptions or the need for maintenance windows
  • Eliminate SPAN port contention, oversubscription, and configuration errors
  • Improve overall switch performance by removing port mirror degradation while freeing valuable ports


  • Unidirectional and invisible to other devices on the network making it impossible to access or infiltrate connected monitoring and analysis tools

Aggregating Data

  • Monitor all network traffic from two different sources
  • Improve network troubleshooting by viewing both sides of a full duplex conversation
  • Combine both directions of a full duplex data stream in a single trace filei
  • Allows flexibility of monitoring devices, including the option to revert to traditional full duplex dual channel data capture, utilizing single NIC probes for advanced monitoring or hardware reduction

Simple Installation

  • Plug and play means simple and fast deployments
  • Auto handelt Einstellungen für Netzwerkgeschwindigkeiten von 10/100/1000 Mbps aus
  • Einzelner Netzwerkausfall für permanente Installation
  • Wird mit einer praktischen Halterung für den Rack-Einbau geliefert, die zusammen mit dem optionalen 1HE-Rack-Montagesatz für bis zu 3 Geräte verwendet werden kann.
  • Plug and Play bedeutet einfache und schnelle Bereitstellungen
  • Auto negotiates settings for 10/100/1000 Mbps network speeds
  • Single network break for permanent installation

  • Redundant power supply option ensures seamless monitoring even if the main power source is unavailable*
  • Inline design allows network connectivity in the event of a power failure

*To eliminate power as a single point of failure two power supplies must be used. The second power supply must be connected to a different external power source circuit than the first power supply. Additional power supplies may be sourced using the specifications provided.
