Select three characteristics of the Cisco coarse wave division multiplexing (CWDM) solution. (Choose three.)
A.
multiplexes up to eight wavelengths across a single fiber pair
B.
supports a maximum connection length of 220 kilometers
C.
supports both linear and ring topologies
D.
requires OADMs (optical add/drop multiplexers) to aggregate multiple wavelengths across the same fiber pair
E.
can be optically amplified to extend the distance characteristics
