A. Dispersion compensation module (DCM)

B. Wavelength router (WR)

C. Optical transponder (OT)

D. Static filter device (SFD)

A. Transport multiple signals transparently, onto several wavelengths, all together over one single fiber

B. Share a single signal among multiple fibers doing load balancing, and thus increasing the reliability of the optical transmission

C. Increase the bit rate of each client signal by spreading it over multiple wavelengths

D. Allocate different signals to different time slots

A. A node with only one direction and therefore a terminal node

B. A node with one direction only and therefore used as In-Line-Amplifier (ILA)

C. A node with only east and west sides without directions towards north and south

D. A node with only one express channel and therefore made of two sides

A. A physical link between two optical amplifiers

B. A link between end points to increase the power budget of the optical link

C. An entity to encapsulate a low order signal into a high order container

D. A transparent transport of a client signal

A. Yes, the user can apply manual changes but only for non-GMPLS nodes, as the control plane reserves node resources not editable by the user

B. Yes, the user can apply manual changes directly from this view

C. Yes, but the user can modify only the node name and location

D. No, this view is used to display a close-up view of the node

A. Compensating for attenuation through an optical-electrical-optical amplification

B. Demodulating the incoming signal

C. Compensating for optical power attenuation

D. Compensating for chromatic dispersion

A. A service is always associated to a single wavelength, while a trail can involve multiple wavelengths.

B. Services are transported over trails; that is, services are clients with respect to trails.

C. A trail can interconnect three ports, while a service always two.

D. Trails are transported over services; that is, trails are clients with respect to services.
