Performance Monitoring
The patch panel uses Optical Test Access Port (TAP) devices to enable passive
access and monitoring in the fiber-optic network. The TAPs enable network-based
intrusion detection system sensors to operate efficiently without interruption.
They send traffic data to a monitoring device by splitting the network signal,
without introducing delay or changing the content or structure of the information
contained in the packets. An OSA (Optical Spectrum Analyzer) or PM (Power
Meter) can be used for optical power monitoring and optical analysis.
shows the manufacturer-specified TAP split ratios for the TAP coupler
optical power in the patch panel. The split ratio denotes the ratio of the TAP input
signal to the output signal.
