NEW QUESTION # 57
Which statement is correct about the NFM-T network map?
Answer: A
Explanation:
The NFM-T network map provides a graphical view of the network with different colors used to represent each node, physical connection, and active alarm. It allows the user to quickly identify any issues in the network and provides context sensitive navigation.
NEW QUESTION # 58
In which of the following forms does the TTI byte provide information on network elements?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
In the Optical Transport Network (OTN) hierarchy, the TTI (Trail Trace Identifier) is a 64-byte overhead signal used to ensure that the source and destination of a path are correctly connected. It is part of the overhead in the OTU (Optical Transport Unit) and ODU (Optical Data Unit) layers. The TTI provides a mechanism for "path trace" to prevent misconnections. It specifically carries the SAPI (Source Access Point Identifier) and the DAPI (Destination Access Point Identifier).
These identifiers are strings that uniquely identify the source and destination ports. By comparing the "Expected SAPI/DAPI" configured on a port with the "Received SAPI/DAPI" actually coming in over the fiber, the Nokia 1830 PSS can detect fiber patching errors or cross-connect mistakes. If there is a mismatch, the system can trigger a TIM (Trace Identifier Mismatch) alarm and potentially squelch the traffic to prevent data from being delivered to the wrong customer. This is a Layer 1 (OTN) function and is entirely independent of Layer 2 MAC addresses or Layer 3 IP addresses used by the management system for DCN (Data Communication Network) connectivity.
NEW QUESTION # 59
What is the purpose of the NFM-T node synchronization?
Answer: D
Explanation:
This is done in order to keep the NFM-T database in sync with the nodes in the network. The synchronization process allows the NFM-T to keep track of any changes that are made to the nodes, such as new nodes added, nodes removed, and so on. By synchronizing the node database with the NFM-T, network administrators can ensure that their network is up to date and running efficiently.
NEW QUESTION # 60
Which of the following are the main reasons for fiber attenuation?
Answer: D
NEW QUESTION # 61
What is the meaning of first, second, and third window in the optical fiber propagation context?
Answer: C
Explanation:
In optical fiber propagation context, the first, second, and third window refer to different wavelength intervals where the WDM (Wavelength Division Multiplexing) optical transmission occurs.
The first window is the lowest loss window and is typically in the range of 1300-1324nm. This is the most commonly used window for long-haul communications.
The second window is the 1550 nm window and is the most widely used window for long-haul and ultra-long-haul communications. This window has a lower attenuation than the first window, but it also has more dispersion, which can limit the maximum transmission distance.
The third window is the range of 1625-1675 nm, it is also called the L-band window. This window has lower attenuation than the first and second window but its usage is limited due to the high cost of equipment and lack of commercial devices.
These windows are used in WDM systems to increase the capacity of the fiber by transmitting multiple channels of data at different wavelengths on the same fiber.
A,C,D are not correct as they are not related to the meaning of first, second, and third window in the optical fiber propagation context.
