A micro-reflection signature consists of what pair of characterizing elements? relative level of the reflected signal compared to the main signal, and the delay of the reflected signal When setting proactive network maintenance (PNM) severity metrics for main tap ratio (MTR), how much level change is typically worthy of attention? 3 dB

- Understanding and Troubleshooting Linear Distortions: Micro-reflections . . .
Micro-reflections • Damaged or missing end-of-line terminators • Damaged or missing chassis terminators on directional coupler, splitter, or multiple-output amplifier unused ports • Loose center conductor seizure screws • Unused tap ports not terminated; this is especially critical on low value taps, but all
- Broadband: What is a Micro-Reflection? | Archives - Cablefax
Simple: A micro-reflection falls into a class of impairments known as linear distortions, and can cause amplitude ripple (standing waves), group delay ripple, inter-symbol interference, and degraded modulation error ratio (MER) What, then, is meant by a reflection’s time delay?
- What are Micro Reflections in a DOCSIS cable plant? Micro Reflections . . .
This video shows you what can cause micro reflections in the return path of a cable plant and describes how an echo cavity is produced
- A Lesson on Transmission Line Theory - Broadband Library
The definition of a micro-reflection according to the PNM Best Practices Primer: HFC Networks (DOCSIS® 3 1) is “A short time-delay echo or reflection caused by an impedance mismatch A micro-reflection’s time delay typically ranges from less than a symbol period to several symbol periods ”
- A micro-reflection signature consists of what pair of characterizing . . .
Let's recall that a micro-reflection signature primarily comprises two characterizing elements: amplitude and time delay Amplitude refers the intensity or size of the reflected signal, whereas time delay signifies the duration taken by the signal to come back following an impedance mismatch or irregularity within a transmission line
- Pre-equalization based pro-active network maintenance process model
The process model for characterizing and isolating the location of the fault is defined using the following processes 1) Network performance monitoring and data collection 2) Evaluation of performance metrics for impairment identification 3) Impairment characterization 4) Mapping of end device to physical path (end device to from HE path)
- Method and apparatus for determining micro-reflections in a network
There are two significant causes of micro-reflections in an upstream HFC plant, impedance mismatches and diplex filters Significant micro-reflections can degrade upstream HFC plant
