NCTI RSC II CABLE NETWORK OVERVIEW:Understanding the Feeder System
What is one of the differences between tree-and-branch and hybrid fiber/coax (HFC)
DESIGNS? - Answer✅ Bandwidth in the downstream path.
In the tree-and-branch design, the cable signal in the downstream path leaves the trunk
at the bridge amplifier. There, It makes a transition to the feeder's domain, and the
signal splits. What is the maximum number of output ports the split signal can be routed
to? - Answer✅ Four.
Which of the following statements accurately describes the relationship between coaxial
cable and attenuation? - Answer✅ Attenuation decreases when the size of the
coaxial cable increases.
Temperature can affect attenuation or signal loss. A 10 Degrees Fahrenheit rise in
surrounding temperature causes which of the following? - Answer✅ A 1% rise in a
cable span's attenuation compared to the cable standard loss value.
In the feeder cable, what will a properly fitted and attached connector do? - Answer✅
Keep internal RF signals in and external signals out.
What is the required impedance that a properly fitted and attached connector will
maintain in the feeder cable? - Answer✅ 75 ohms.
Which type of feeder amplifier distributes the signal to the connected feeder cables (up
to four) through a feedermaker? - Answer✅ Bridger amplifier.
Which type of passive device function is such a way as to equally divide the RF signal
so the feeder can run in tow different directions simultaneously? - Answer✅ Line
splitter.
What is the tap's insertion loss? - Answer✅ It is the amount of signal loss between
the tap's input and output ports.
What is isolation? - Answer✅ Isolation is the amount of signal reduction that an active
device has between to output ports.
