What is a trail?
A. An entity to encapsulate a low order signal into a high order container
B. A transparent transport of a client signal
C. A link between end points to increase the power budget of the optical link
D. A physical link between two optical amplifiers
Answer
B. A transparent transport of a client signal
Explanation
The correct answer is B. A transparent transport of a client signal.
A trail is a point-to-point connection between two network elements. It is a logical entity that is used to transport a client signal from one network element to another. The client signal can be any type of signal, such as an Ethernet signal, a SONET/SDH signal, or a wavelength signal.
The trail is responsible for the transparent transport of the client signal. This means that the trail does not modify the client signal in any way. The client signal is simply transported from one network element to another.
The trail is also responsible for the protection of the client signal. This means that the trail will ensure that the client signal is not lost or corrupted during transmission.
The trail is a key component of any optical network. It is responsible for the transparent transport and protection of the client signal.
The other options are incorrect because they do not accurately describe a trail. Option A is incorrect because a trail is not an entity that encapsulates a low order signal into a high order container. Option C is incorrect because a trail is not a link between end points to increase the power budget of the optical link. Option D is incorrect because a trail is not a physical link between two optical amplifiers.
