B. Coaxial cable
C. Fiber optic cable
D. Telephone line
Fiber optic cable supports extremely high data rates and long-
distance transmission with minimal signal loss, making it ideal for
broadband backbone infrastructure.
2. What is the primary function of an Optical Network Terminal (ONT)?
A. Amplify radio signals
B. Convert optical signals to electrical signals
C. Encrypt network traffic
D. Route IP packets
An ONT converts incoming fiber-optic light signals into electrical
signals usable by customer equipment.
3. Which tool is used to measure optical power in fiber systems?
A. Multimeter
B. Tone generator
C. Cable tester
D. Optical power meter
, An optical power meter measures the strength of light signals in fiber
optic networks to verify proper signal levels.
4. What does OTDR stand for?
A. Optical Transmission Data Relay
B. Optical Time Domain Reflectometer
C. Optical Telemetry Data Router
D. Output Transmission Diagnostic Recorder
An OTDR is used to test fiber optic cables by sending light pulses and
analyzing reflections to locate faults.
5. Which connector type is commonly used in fiber optic broadband
installations?
A. RJ45
B. BNC
C. SC connector
D. F-type
SC connectors are widely used in fiber optic networks due to their
reliable performance and ease of use.
6. What is the purpose of grounding in broadband installations?
A. Increase signal speed
B. Improve data encryption
C. Protect equipment from electrical faults and surges
D. Reduce bandwidth usage
Proper grounding protects technicians and equipment from electrical
hazards and lightning-induced surges.
7. Which protocol is commonly used for internet communication?
A. FTP
B. SMTP
C. TCP/IP
D. HDMI
TCP/IP is the foundational protocol suite enabling reliable internet
communication.
8. What does latency refer to in a broadband network?
A. Data storage capacity
B. Signal strength
C. Delay in data transmission
, D. Cable length
Latency measures the time it takes for data to travel from source to
destination.
9. Which device distributes network traffic within a local area network?
A. Modem
B. Switch
C. Repeater
D. Splitter
A switch connects devices within a LAN and forwards data only to the
intended recipient.
10. What is the function of a modem in broadband systems?
A. Increase signal encryption
B. Modulate and demodulate signals
C. Store data packets
D. Filter viruses
A modem converts digital signals to analog and back for
transmission over certain media.
11. Which safety equipment is required when working with fiber
optics?
A. Rubber gloves only
B. Steel-toe boots
C. Safety glasses
D. Ear plugs
Safety glasses protect technicians from harmful fiber shards during
installation and splicing.
12. What is signal attenuation?
A. Signal amplification
B. Loss of signal strength over distance
C. Signal encryption
D. Packet routing
Attenuation refers to the reduction in signal strength as it travels
through a medium.
13. Which device regenerates weakened signals in a network?
A. Router
B. Modem
