Fiber Optical Taps Features

A Flexible and Scalable Solution for 100% Visibility

Built using fiber optics, Flex Tap fiber taps deliver 100% visibility into network traffic and permanent, passive access points while preserving top network performance.

Flex Taps enable effective network performance, avoiding degradation and disruption. Each versatile Flex Tap is compatible with all protocols and monitoring devices, and you can deploy them at any inline connection on the network without increasing overhead or management workflows. Flex Taps consist of a base chassis unit that can accommodate up to 36 LC links or 12 MTP-based modules.

Passive fiber taps, such as Keysight Flex Taps, are very secure once integrated into a network. They remain live and resist hacking and disablement. A key aspect of selecting a tap is calculating a light budget to ensure that a passive tap does not cause any dropped packets on the monitored network.
