NEW QUESTION # 56
Which of the following are the main reasons for fiber attenuation?
Answer: D
Explanation:
Scattering and absorption are the main reasons for fiber attenuation. Scattering occurs when light bounces off the sides of the fiber, while absorption happens when light is absorbed by the glass or other materials that make up the fiber. Chromatic dispersion (CD) and polarization mode dispersion (PMD) are also factors that can cause attenuation, but they are not the main causes. Small channel spacing can also cause attenuation, but it is a secondary factor and is only significant in certain cases.
NEW QUESTION # 57
Which of the following sentences about FlexGrid is false?
Answer: D
Explanation:
FlexGrid is a flexible grid technology that allows for variable channel spacing and bandwidth allocation. It uses the same sets of boards as the traditional fixed grid systems and it does not require upgrading the old generation WDM systems.

NEW QUESTION # 58
Which statement is correct about node synchronization?
Answer: D
Explanation:
Node synchronization is a process of keeping the NFM-T database in sync with the nodes in the network. The synchronization process will download all the items from the node, including NE parameters, ports, alarms, internal links, etc., to the NFM-T database. This ensures that the NFM-T database is up to date and the network is running efficiently.
NEW QUESTION # 59
What is a trail?
Answer: A
Explanation:
A trail is a transparent transport of a client signal. A trail is a physical link between two points in an optical network, allowing for the transport of a client signal from one point to the other. It is a low-order signal, such as a 10G Ethernet or a Fibre Channel signal, encapsulated into a high-order container, such as a 40G or 100G signal. This allows for the transport of the client signal over longer distances, increasing the power budget of the optical link.
NEW QUESTION # 60
Which of the following statements about the contentionless feature on a CDC-F node is TRUE?
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
The term CDC-F stands for Colorless, Directionless, Contentionless, and Flex-grid. While "Colorless" allows any wavelength on any port and "Directionless" allows any port to be routed to any output fiber (degree), Contentionless solves a specific physical limitation of traditional multiplexers. In a standard ROADM, you cannot drop the same wavelength (e.g., Channel 21) from two different directions (e.g., North and West) into the same add/drop structure because they would "contend" or collide on the same internal fiber.
A Contentionless architecture (typically utilizing a Multicast Switch or MCS) allows the node to drop the same wavelength from different degrees simultaneously without interference. This is critical for high-availability mesh networks where a single transponder might need to receive a specific wavelength from a primary path and a backup path. Without contentionless capabilities, operators would have to carefully manage wavelength assignments across the entire network to ensure no two identical frequencies ever meet at the same drop structure, which significantly complicates planning and restoration.
