A. Refraction and reflection
B. Chromatic dispersion (CD) and polarization mode dispersion

D. Small channel spacing
A. Designs created with an older release can be opened by a current release but cannot make changes.
B. Only designs created with the current release can be opened and edited.
C. Only designs created with current and older releases can be opened and edited.
D. No restrictions are imposed on the software release.
A. The systems are displayed on the CPB panel, however they cannot be individually selected as they need to run all together
B. The systems are not reported on CPB, as this Is transparent to the user and the whole network is validated and provisioned in one step
C. The systems are not reported on CPB, but only through the Equipment Manager
D. The systems are displayed on the CPB panel and they can be individually selected
A. Through the pre-amplifier, the optical signal is amplified within the node internally to recover internal losses due, for instance, to cascaded filters.
B. Through the pre-amplifier, the optical signal is amplified at the transmitter side before it is sent to the line span.
C. Through the pre-amplifier, the optical signal is amplified at the receiver side after it travels along the fiber from another node.
D. Through the pre-amplifier, the optical signal is amplified both the receiver side and at the transmitter side.
A. As the incoming signal power increase, the gain of the amplifier is reduced.
B. The amplification is done simultaneously for all channels as they enter the board.
C. The pump light travels in the opposite direction of the signal to be amplified, amplifying it while it arrives from the adjacent node.
D. The pump light travels in the same direction of the signal, amplifying it while it flows in the fiber towards the following node.
