is designed for short-distance connections and has only a few lambdas, with a greater space between lambdas. Group of answer choices Dense wavelength division multiplexing (DWDM) Fixed wavelength division multiplexing (FWDM) Coarse wavelength division multiplexing (CWDM) Inverse wavelength division multiplexing (IWDM)

The answer is Coarse wavelength division multiplexing (CWDM)

Explanation:

CWDM is the wavelength designed for short- distance connections  and has only a few lambdas. It is mostly used nowadays as a type of wavelength technologies deployed in cities and inner access ways. It is inexpensive and thus a cost effective wavelength  division multiplexing. Cost effective lasers can be used in CWDM due to the spacing of about 20nm between its wavelengths.

Coarse wavelength division multiplexing (CWDM) is designed for short-distance connections and has only a few lambdas, with a greater space between lambdas

Explanation:

Over a long period of time, Wavelength division multiplexing, WDM has been used for transferring large amounts of data between sites. It increases bandwidth by allowing different data streams to be sent simultaneously over a single optical fiber network. In doing this, WDM maximizes the usefulness of fiber and helps optimize net\work investments.

There exist two main types of technology for wavelength division multiplexing (WDM): coarse (CWDM) and dense (DWDM). Both of them use multiple wavelengths of light on a single fiber, but they differ in their spacing of the wavelengths, number of channels and ability to amplify the multiplexed signals.

Unlike with CWDM, the wavelengths in DWDM are more tightly packed, and connections can be amplified. This means that data can be transmitted via much longer distances in the DWDM, whereas, data can be transmitted via much shorter distances in the CWDM.
