10 Gigabit LR Single-Mode Fiber Tap (9 Micron 50/50 Split)

Permanent Inline Monitoring and Analysis on Your 10 Gig Single-mode Fiber Network

Permanent Inline Monitoring and Analysis on Your 10 Gig Single-mode Fiber Network

The USRobotics 10 Gigabit Fiber Taps provide an easy method to rapidly and effectively deploy analysis tools to observe and monitor traffic non-intrusively between two devices on a fiber network. By design, fiber taps are totally passive, fault-tolerant, and invisible to the network which means they will not affect network performance or integrity and can be trusted for permanent installations on a fiber network that require a dedicated port mirror.. These rock solid devices are ideal for real-time monitoring and analysis of any traffic between critical network devices such as switches, routers and firewalls and continue to pass errors that aren't seen using SPAN ports. Topology independent, the taps can be used for ATM, Gigabit, OC3-OC48, or SONET protocols and are available for both Single-mode and Multimode fiber networks.


Monitoring & Analysis

  • Captures and delivers a copy of all traffic to any analysis tool
  • 100% visibility into the network - including VLAN tags
  • View all traffic on both sides of full duplex links
  • Reduces degradation of switch performance due to port mirroring
  • View Layer 1 and 2 errors such as runts and CRC errors not seen when performing network monitoring using SPAN ports
  • Full duplex monitoring
  • Best method to measure network link's performance
  • Great for network analysis and troubleshooting, IDS and monitoring applications

Network Stability

  • 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
  • Minimize traffic delay
  • Fault-tolerant design

Secure & Reliable

  • Passive access means no interference of network traffic
  • Invisible on the network - no IP address means additional security
  • No single point of failure
  • Network traffic will continue to pass uninterrupted

Excellent Compatibility

  • 50/50 split ratio
