HFC NETWORK
Field Techs are responsible for this part of the HFC Network
What is the Tap to the CPE
How many inches of sag should an aerial drop have per 50 feet?
What is 6 inches
A signal making 1 alternating cycle per second would have a frequency of:
What is 1 Hertz
The 5 factors of attenuation are:
This tool is used to determine length, locate faults & passives on the line
What is Time Domain Reflectometer (TDR)
This component of the HFC Network is where the fiber optic signal is converted to an electric signal that travels through coax
What is the Node
This type of cable is not carried by Charter, we only carry the fittings
What is RG-59
1 mV measured across 75 ohms is equal to:
What is 0 dBmV
Your upstream reading at the output of a balanced 3-way splitter is 49.5 dBmV. What is it at the input?
What is 44 dBmV
This tool can help identify which interior wire is going to which room
What is Toner & Probe
This is where the CMTS is located
This is the minimum distance a span clamp should be installed from a tap
What is 6"
This is Charter's upstream frequency range
What is 5-42 mHz
This unit of measurement reflects signal loss/gain
What is dB
This tool is used on CLI jobs
What is Leakage Detector (dipole/field probe/HL Seeker)
This borough in NYC is where the S hub is located
What is Brooklyn
If cables and power lines run parallel, keep them a minimum of ___ inches apart and if they intersect, keep them at ___ degree angles
The number of alternating cycles per second a signal is making at 550 mHz is:
What is 550 million
57 mHz shows a reading of -7 dBmV at the output of a 2 way splitter. What is it at the input?
What is -3.5 dBmV
This tool can be useful for accessing NIDs and tightening span clamps
What is Can Wrench
This is an active device which decreases attenuation within the plant
What is an Amplifier
To protect drop cable when it enters and exits the ground, the conduit must go at least ___ inches into the ground with an ____ inch deep hole to accommodate the proper bend radius.
What is 3 and 8
The LTE 4G frequency band is:
What is 698-806 mHz
This is the loss of the passive leg on an Integrated Signal Amplifier
What is 3.5 dB
To test for ingress on downstream frequencies using my Viavi meter, I would go to ChannelCheck and scroll down to
What is IUC/Ingress Under Carrier
