Question
Which of the following statements about the contentionless feature on a CDC-F node is TRUE?
A. It represents the ability to support the Fixed Grid standard.
B. It represents the ability to drop any lambda from any Add/Drop block port.
C. It represents the ability to reroute lambdas to any direction.
D. It represents the ability to drop the same wavelength from different degrees.
Answer
D. It represents the ability to drop the same wavelength from different degrees.
Explanation
A CDC-F node (Colorless, Directionless, Contentionless, and Flexible Grid) is a type of Reconfigurable Optical Add-Drop Multiplexer (ROADM) that plays a key role in modern optical transport networks. Each feature contributes to making the network more flexible and scalable, particularly in wavelength routing and management.
Contentionless refers specifically to the ability of the system to handle traffic on the same wavelength across different directions without interference or conflict. This enables a more dynamic network, as multiple connections can use the same wavelength in different signal paths simultaneously.
Option D is correct because it describes the contentionless capability accurately. The ability to “drop the same wavelength from different degrees” means that the node can manage identical wavelengths from different input directions without them interfering, offering significant flexibility in network configuration.
Option A (Fixed Grid standard) refers to wavelength spacing rules and does not reflect the dynamic and flexible nature of contentionless operation, making it incorrect.
Option B refers to colorless capability, which allows any wavelength to be added or dropped at any port, not necessarily related to contentionless operation.
Option C describes a directionless feature, which refers to the ability to route signals to any output direction, but not specifically the contentionless aspect of a CDC-F node.
In summary, the contentionless feature focuses on enabling network flexibility by allowing the same wavelength to be utilized from different directions, enhancing wavelength usage efficiency in high-capacity optical networks.
