질문 # 39
What is the function of the express channel interface?
정답：C
설명：
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
In the context of WDM (Wavelength Division Multiplexing) node architecture, an express channel interface (often associated with OADMs or ROADMs) is specifically designed to handle "through" traffic. In a multi-node optical network, not every wavelength (channel) needs to be processed or terminated at every site it passes. To maintain signal integrity and reduce latency, these wavelengths are kept in the optical domain.
The express interface allows these optical channels-those not terminated or "dropped" at the local node-to bypass the local transponders and multiplexers, flowing directly to the downstream node. This photonic bypass avoids unnecessary O-E-O (Optical-Electrical-Optical) conversions, which would otherwise require expensive hardware and increase power consumption. By utilizing express paths, the Nokia 1830 PSS can scale to support massive core network capacities while ensuring that only the relevant traffic is diverted to the local client-facing ports.
질문 # 40
Which of the following statements best describes the definition of PCT?
정답：D
설명：
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
The Photonic Connectivity Tool (PCT) is a specialized utility within the Nokia 1830 PSS ecosystem designed specifically for modern, complex node architectures. As networks evolved toward CDC-F (Colorless, Directionless, Contentionless with Flex-grid), the internal fiber cabling within a single node became significantly more complex, involving numerous connections between WSS modules, Multicast Switches (MCS), and amplifiers.
The PCT is used to validate internal fiber connectivity, ensuring that the physical "patching" matches the intended design before service provisioning begins. It leverages the OSRP (Optical Signal Routing Protocol) or specialized control plane mechanisms to verify that light can flow through the internal cross-connects as expected. This tool is essential for reducing human error during the installation of high-degree ROADM sites, where dozens of internal fibers must be correctly mapped to ensure the "Directionless" and "Contentionless" features function without blocking.
질문 # 41
Which of the following statements about the contentionless feature on a CDC-F node is TRUE?
정답：D
설명：
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.
질문 # 42
By using the EPT run design command, are the previously designed elements removed?
정답：B
설명：
The EPT run design command can remove previously designed elements, but the user is prompted to choose whether to delete them or leave them intact. This allows the user to progress their design while still keeping the existing elements in place. If the user selects to leave the existing elements, then they will remain in the same slots. If GMPLS nodes are used, the existing slots cannot change as they are controlled by another manager (GMRE).
질문 # 43
What is a degree-1 node?
정답：B
설명：
A degree-1 node is a node that only has one direction, and it is therefore a terminal node. This means that the node only has one input and one output port. It does not have any other ports to connect to other nodes or fibers. This is a common feature of some optical transport networks, such as ring networks, where a degree-1 node serves as the endpoint of the ring.
