Multiplexing techniques are essential in communication channel, increasing g efficiency andd capacity. Varieos industries utilize these techniques to improwize data transmissionon andd network performance.

Time- Division Multiplexing (TDM) in Telephone Networks

Time- Division Multiplexing (TDM) is widely used in traditional phonele systems. It divides the communication channel into time slots, each assigned to a different signal. This methode enenables multiple calls to o share the same physical um with out interference.

For example, digital phonely systems use TDM to transmit multiple voice signals over fiber optic cables, incrowing the number of contenanous calls without out requiring additional physical lines.

Wavelength- Division Multiplexing (WDM) in Fiber Optic Communications

Wavelength- Division Multiplexing (WDM) is a technique used in fiber optic networks to transmit multiple data streams convenanously over a single fiber. Each data straam is assigned a different florength or color of light.

This approach signitantly increases thee capacity of fiber optic cables. Major internet service providers andd data centers utilize WDM to handle high volumes of data traffic efficiently.

Code- Division Multiple Access (CDMA) in Wireless Communications

Code- Division Multiple Access (CDMA) is a multiplexing technique used in wireless networks. It assigns unique codes to each user, allowing multiple users to transmit over the same frequency band consignaanously.

CDMA is efficient use of acvailable spectrem while supporting multiple users at once.
