Flex-PON board can support GPON/XG(S)-PON/Combo PON, 3-in-1.
- A. False
- B. True
Answer: B
Explanation:
The statement isTrue. TheFlex-PON boardis a versatile solution designed to support multiple PON technologies, including:
* GPON (Gigabit Passive Optical Network):Suitable for residential and small businessapplications.

NEW QUESTION # 45
Which of the following optical modules are used in commercial case currently?
- A. Class D
- B. Class E
- C. Class C+
- D. Class F
- E. Class B+
Answer: C,E
Explanation:
The correct answers areClass B+andClass C+. These optical module classes are widely used in commercial GPON deployments due to their balance of performance, cost, and reliability.
* Class B+:Supports transmission distances up to20 kmand is commonly used in urban and suburban areas. It provides sufficient power budget for most residential and small business applications.
* Class C+:Supports longer distances (up to40 km) and higher split ratios, making it idealfor rural or remote areas where extended reach is required.
Other options:
* Class D:Not a standard classification for GPON optical modules.
* Class E and F:These classifications do not exist in current GPON standards.
The choice between Class B+ and Class C+ depends on the specific deployment scenario, including distance, split ratio, and environmental conditions.
