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
