Which two options are characteristics of the NCS 2000 add/drop/express patch panels? (Choose two.)
The correct answer is A. passive C. modular. The NCS 2000 add/drop/express patch panels are passive - they contain no active electronics, require no power supply, and rely purely on fiber optic connections and splitters/couplers to route wavelengths. They are also modular, meaning they slot into the NCS 2000 chassis in a…

Explanation
The NCS 2000 add/drop/express patch panels are passive - they contain no active electronics, require no power supply, and rely purely on fiber optic connections and splitters/couplers to route wavelengths. They are also modular, meaning they slot into the NCS 2000 chassis in a flexible, scalable way, allowing operators to customize configurations without replacing the entire system.
Option B (coherent) is wrong because "coherent" describes a transmission technique used in transponders and line cards (advanced modulation/detection), not in patch panels. Option D (high power) is wrong because passive components by definition neither amplify nor consume significant power - high power is a trait of amplifiers (like EDFAs), not patch panels.
Memory tip: Think "PM" = Patch panels are Passive and Modular. If a choice implies electricity or fancy signal processing (coherent, high power), it belongs to active components - not a patch panel.
