Disadvantages of coarse wavelength division multiplexing
DWDM Disadvantages: · High Cost: Significant investment in both initial hardware and ongoing operations. · Complexity: Requires careful planning, precise engineering, and specialized skills to manage. · Power and Space Intensive: Amplifiers and control units consume considerable. While WDM offers many advantages, it also has some drawbacks: Signal Separation: Signals must be sufficiently spaced apart in frequency to avoid interference. Limited to Point-to-Point Circuits: Light waves carrying WDM signals are typically restricted to two-point connections. Scalability. Wavelength Division Multiplexing (WDM) allows multiple data streams to be transmitted simultaneously over a single optical fiber. · Low Power Consumption: Ideal for space- and power-constrained environments like enterprise data centers.
