Cable loss/Attenuation
What frequencies attenuate more than the other?
Higher frequencies.
What does CMTS stand for?
Cable Modem Termination System.
What device shows you faults and the distance to them?
OTDR.
PathTrak and Ingress expert is a tool that is called what?
A Spectrum Analyzer.
What is a PI?
Combine AC and RF.
What component attenuates signal across the entire spectrum?
Pads.
In a TDR trace, what type of cabling issue does an downward direction represent?
A short.
What is a Macrobend?
A bend in the Fiber cable.
What is CPD?
Common Path Distortion.
What is the input Voltage of a PS?
120v AC
Cable size, length, Dielectric type, carrier frequency, and temperature is used to calculate what?
Attenuation.
What does OFDM stand for?
Orthogonal Frequency Division Multiplexing
What is a Microbend?
70-75% of noise comes from what?
The Drop system.
What is an SPI do?
Provide power to the plant from the PS.
What component is used to compensate for the lack of cable attenuation?
Cable Sim or SCS.
An impedance greater than 75 Ohms does creates what?
Wave Division Multiplexing does what?
WDM transmits more information without increasing the number of fibers
Why are low value taps susceptible to ingress?
Tx is lower due to low value taps.
What does the inverter module do?
Convert DC to AC power.
What does extremely high levels from an active cause?
Distortion.
What does the Diplexer do?
Separate Forward and Return.
What protocol is used to transfer data over optical fiber?
SONET (Synchronous Optical Networking)
How can you determine when there's noise coming from the hub via PathTrak?
What does the transformer module do?
Step down from 120v to 89 or 63v AC.
