Which of the following communication technologies would MOST likely be used to increase bandwidth over an existing fiber optic network by combining multiple signals at different wavelengths? wavelength can support as many as 160 simultaneous transmissions using more than eight active wavelengths per fiber.
A.
DWDM
B.
SONET
C.
ADSL
D.
LACP
Explanation:
Dense wavelength-division multiplexing (DWDM) is a high-speed optical network type commonly used in MANs
(metropolitan area networks). DWDM uses as many as 32 light wavelengths on a single fiber, where each
