Which of the following statements about optical power vs amplification stages is TRUE?

• A.Ingress amplifiers are always more powerful [than egress amplifiers, to reduce the impact of non-linear effects.
• B.When channels pass through amplifiers, all of them always experience a similar amplification.
• C.When multiple channels pass through a shared port (for example, an amplifier line interface), the total aggregated power reflects the number of channels currently present.
• D.The Optical Supervisory Channel (OSC) is amplified when passing through all amplifier types, except for Raman which is not based on EDFA.

Refer to the exhibit, which shows a conditions list from the 1830 PSS GUI. (i) What is the total number of alarms reported? (ii) How many service affecting alarms are displayed? (iii) How many conditions are displayed?

• A.(I) total number of alarms = 5
  (ii) number of serviceaffectingalarms = 2
  (Hi) number of conditions = 14
• B.(i) total number of alarms = 7
  (ii) number of service affecting alarms = 5
  (Hi) number of conditions = 7
• C.(i) total number of alarms = 2
  (ii) number of service affecting alarms = 2
  (Hi) number of conditions = 18
• D.(i) total number of alarms = 4
  (ii) number of service affecting alarms = 14
  (iii) number of conditions = 2

Consider the exhibit. A single directional fiber cut is occurring between two amplifiers in unidirectional configuration with Raman pump.
Multiple services are crossing the affected span.
Which node(s) will report an Incoming Payload LOS" alarm?

• A.No node, as a Raman pump is used in Node A.
• B.Node C only.
• C.Both Node A and Node C
• D.Neither Node A nor Node C.
