NEW QUESTION # 72
To prevent the optical power at the receive end of an OTU board from being excessively high, you must configure a fixed attenuator according to the actual optical power. The fixed attenuator is usually configured at the transmit end.
- A. FALSE
- B. TRUE
Answer: A
Explanation:
The fixed attenuator is usually configured at the receive end, not the transmit end, to prevent the optical power at the receive end of an OTU (Optical Transport Unit) board from being excessively high. High optical power at the receiver can cause signal distortion or damage the receiver module. Configuring the attenuator at the receive end ensures that the incoming signal power is within the optimal sensitivity range of the receiver.
Configuring attenuators at the transmit end is generally ineffective because it reduces power output before transmission, potentially reducing reach. This approach aligns with HCIP-Transmission best practices for optical power management and receiver protection.
NEW QUESTION # 73
When the line board scheduling granularity is ODUflex, which of the following protections can be supported?
- A. SW SNCP protection
- B. ODUK ring network protection
- C. ODUk SNCP protection
- D. Tributary SNCP protection
Answer: C
NEW QUESTION # 74
Which of the following is not a trigger condition for the automatic switching of client 1 +1 protection?
- A. The OTU board reports the OTUk_LOF alarm.
- B. When SD is disabled, the OTU board reports the ODUk_PM_DEG alarm.
- C. The OLP or DCP board reports the R_LOS alarm.
- D. The OTU board cannot be detected.
Answer: B
Explanation:
Among trigger conditions for automatic switching in client 1+1 protection, (A) is false. When SD (Signal Degrade) is disabled, the OTU board does not report an ODUk_PM_DEG alarm as a trigger for switching.
Other triggers like the OTU board not detected, OTUk_LOF alarm, and R_LOS alarm reported by OLP or DCP boards are valid triggers for switching. This behavior prevents unnecessary protection switching when SD monitoring is disabled, which helps avoid service disruptions. HCIP-Transmission explains these nuances in protection switching logic to optimize network resilience and reliability.
NEW QUESTION # 75
The unprotected chain consists of four network elements: NE1.NE2.NE3 and NE4. Create an end-to-end VC4 path NE1-NE4. Add NE5 between NE2 and NE3 for capacity expansion. The original configuration remains unchanged. No service is configured on NE5.
In this case, the unprotected chain becomes NE1-NE2-NE5-NE3-NE4, how many VC4 paths can be searched out?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
NEW QUESTION # 76
Which of the following statements about the TMK1UNS5 board is false?
- A. It supports the transmission of OTN services with a total bandwidth of not higher than 200 Gbit/s.
- B. It is a universal line board that supports hybrid transmission of OTN, SDH, and packet services.
- C. It supports regeneration mode, which can be used at an electrical regeneration site in the system to implement the electrical regeneration of corresponding optical signals.
- D. It supports hybrid transmission of ODU0, ODU1, ODU2, ODU2e, ODU3, ODU4, and ODUflex signals.
Answer: C
Explanation:
The TMK1UNS5 is a universal OTN line board that operates in 100 G and 200 G line modes and supports hybrid OTN/SDH/packet mapping (including ODU0, ODU1, ODU2/2e, ODU3, ODU4, and ODUflex) as well as FEC, OSC, and 1+1 protection. Its published "Functions and Features" do not include an electrical 3R regeneration mode, so it cannot be used as a regenerator.
NEW QUESTION # 77
When light passes through a passive optical component, the optical power decreases. This decrease is called an insertion loss.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
When light passes through a passive optical component, the decrease in optical power is termed insertion loss.
This is a fundamental concept in optical transmission where every component like connectors, splices, splitters, or filters adds some level of power attenuation. Managing insertion loss is crucial to maintain overall system performance, especially in long-haul or dense WDM systems where accumulated loss can degrade the signal. HCIP-Transmission emphasizes the importance of measuring and minimizing insertion loss to ensure system stability and reach requirements are met.

- A. The timing starts from the entry of the first bit of the data frame, and ends when the first bit of the data frame appears on the output terminal P. The time difference between the two is the delay of the bit forwarding device
- B. The timing starts from the entry of the first bit of the data frame, and ends when the first bit of the data frame appears on the output terminal P. The time difference between the two is the delay of the bit forwarding device
