Visibility on Tap — Optical Fiber Taps

Problem: Sacrificing Performance For Security

These days, organizations demand reliable, continuous visibility into network traffic. But network monitoring and security tools can lead to network performance degradation and disruption if not used carefully.

This presents a unique challenge to today’s enterprises, government agencies, and service providers: how to achieve total traffic visibility for network monitoring and security tools without introducing points of failure in the network.

Solution: A Flexible and Scalable Solution For 100% Visibility

Built using fiber-optics, our Flex Tap fiber taps deliver 100% visibility into network traffic and permanent, passive access points while preserving top network performance. That’s because each tap in the Keysight Flex Tap™ family is modular and can support network speeds of up to 400Gbps, and is 100% passive.

At the same time, Flex Taps allow you to effectively monitor network performance, avoiding issues of degradation and disruption. Flex Taps are also versatile: each is compatible with all protocols and monitoring devices, and can be deployed at any inline connection on the network without increasing overhead or management workflows. Flex Taps consist of a base chassis unit that can tap to 36 LC links, or 12 MTP based modules.

Passive fiber taps such as Keysight Flex Taps are very secure as once inserted in a network. They are always live and cannot be 'hacked' and disabled. A key aspect of selecting the right tap for the job is the calculation of a 'light budget' that confirms that a passive tap will not lead to any dropped packets on the network being monitored.
