Keysight Patch Tap

Data Sheets

The newest addition to our fiber taps is the Patch Tap— for use in your patch panels and fiber distribution frames. The Patch Tap has superior Insertion Loss specifications, bend insensitive fibers, innovative splitter technology, and a totally new deployment strategy. For financial markets it offers lower latency through both low light path length and the ability to integrate into patch panels. The Patch Tap can be integrated into major manufacturers’ patch panels, enabling passive tapping of your network while reducing rack space requirements and light loss budget.   The Patch Tap is available in Multimode and Single mode fiber, in the most common split ratios of 50/50 and 70/30, in speeds from 100G to 1G. The latency of the standard patch taps is around 1.3 nSec whilst the Ultra-Low Latency Patch tap is less than 0.8 nSec.  The design of the Patch Tap is optimized and tested for high-performance fiber networks. Flex Taps are deployed at any inline connection on the network; therefore, no additional overhead or management burden is added to the network devices to copy traffic for the monitoring/security infrastructure. The Patch Tap is compatible with all major manufacturers’ monitoring devices, including protocol analyzers, probes, and intrusion detection systems. The Patch Tap is network protocol agnostic. Each Multimode Patch Tap is capable of 1G, 10G and 25G speeds. Each Single Mode Patch Tap is multi-speed from 1G to 400G speeds.



• For use in your patch panels and fiber distribution frames

• No exterior housing

• Ultra-low latency patch taps with shortest length of 0.14m to achieve lowest possible latency

• Single Mode fiber speeds of 400G/100G/50G/40G/25G/10G/1G

• Multimode fiber speeds of 25G/10G/1G

• 50/50 and 70/30 split ratios

Key Features

• Integrated into the structured cabling systems. 

• No additional segments in the channel link – fits easily into most major manufacturer's patch panels.

• Lower latency than traditional modular taps.

• Integrated tail cable – Ultra Low Latency taps include a 3m long fiber tail to reduce connector losses.

• Fully Passive – Monitoring infrastructure does not impact network availability and reduces operating cost without adding management overhead.

• MACs (Moves, Adds, Changes) won't disrupt live traffic.

• Patch panel vendor agnostic – now you have a choice for integrated taps. No more sole source procurement.
