CATV
What is Community Antenna Television?
Most modern cable plants utilize both fiber optic and RF components, and are described as these types of networks.
What are HFC (Hybrid Fiber Coax) Networks?
This is the first layer of the OSI 7-Layer model.
What is the Physical Layer?
This is what OSHA stands for.
What is Occupational Safety and Health Administration?
Over-the-air signals “leaking” into the cable network through loose connectors and compromised shielding is known as this.
What is ingress?
CMTS
What is Cable Modem Termination System?
This takes commercial power and combines it with RF onto the hardline.
What is a power inserter?
This protocol uses hexadecimal digits, and arose out of the concern that the number of internet connected devices would outpace the number of available IP addresses.
What is IPv6?
After visually inspecting the work area for hazards, you should check the pole and all attachments, such as down guys, for this before touching anything else.
What is foreign voltage?
This impairment is typically caused by the presence of water in the cable or in a passive device, causing a gradual decrease in signal strength, especially at higher frequencies (high doesn’t swim).
What is rolloff?
DOCSIS
What is Data Over Cable Service Interface Specification?
If you need to connect a tap directly to a splitter with no hardline between the two, just use one of these.
What is a housing to housing (or pin to pin) connector?
If you are not using a static IP address, then your device likely uses this server to receive an IP address.
What is a DHCP (Dynamic Host Configuration Protocol) Server?
Your safety glasses should have this ANSI rating.
What is Z87.1?
Caused by impedance mismatches within the cable plant, this type of standing wave is most commonly seen as a single notch RF impairment that often spans multiple channels.
What is a suckout?
ANSI
What is American National Standards Institute?
These can be found in amplifiers, and separate the forward and return paths.
What are diplex filters?
This is the largest Wide Area Network in the world.
What is the Internet?
This class of safety vest should be worn when working near traffic exceeding 50 miles per hour.
What is class 3?
Seen as gain at specific frequencies, and usually caused by grounding problems in actives. Easily recognized as an upward change in amplitude that peaks and then reduces in amplitude.
What is resonant peaking?
TDMA
What is Time Division Multiple Access?
To power the module, most signal amplifier power packs convert AC in the plant into this.
What is 24 VDC (volts direct current)?
TCP/IP is short for this.
What is Transmission Control Protocol/Internet Protocol?
Information on workplace chemicals, such as ingredients, proper storage, dangers, first aid, etc., can be found in these.
What are MSDS (Manufacturer’s Safety Data Sheets)?
This nonlinear impairment is caused by corrosion creating an oxide layer that behaves like a diode, and will commonly appear as an elevated noise floor across the spectrum of a digital network.
What is CPD (Common Path Distortion)?
