Question #105
Which of the following definitions about POL is correct?
- A . Passive Optical LAN, is the application of PON technology in the enterprise campus environment
- B . Procurement on Line, Purchasing Online System
- C . Port of Loading, the loading port where goods are initially shipped
- D . Point of Load
Correct Answer: A
A
Explanation:
POL (Passive Optical LAN) refers to the application of Passive Optical Network (PON) technology in enterprise campus environments. It is a modern networking solution that replaces traditional copper-based Ethernet networks with fiber optics, offering higher bandwidth, longer reach, and lower maintenance costs. POL is widely used in scenarios such as education, healthcare, hospitality, and smart cities.
The other options―Procurement on Line, Port of Loading, and Point of Load―are unrelated to optical networking and refer to entirely different concepts.

Question #106
What’s the minimum protection switching time of Link-layer Type B Switching?
- A . 50ms
- B . 3s
- C . 3min
- D . 1min
Correct Answer: A
A
Explanation:
The minimum protection switching time for Link-layer Type B Switching in GPON is50ms. Type B protection involves protecting the fiber link between the OLT and the splitter by providing redundant fibers. In the event of a fiber failure, the system switches to the backup fiber within 50ms to ensure minimal service disruption. This fast switching time is critical for maintaining high availability and reliability in GPON networks.
3s, 3min, 1min: These times are far too long for protection switching in modern optical networks, which require near-instantaneous recovery to meet SLA (Service Level Agreement) requirements.
