Which constraint is relieved by Wavelength Division Multiplexing (WDM) in optical fiber networks?

💡 Explanation

WDM allows multiple data streams to share a single fiber because it employs frequency division multiplexing in the optical spectrum. Therefore, it increases total bandwidth rather than addressing dispersion issues, which require different solutions.

• Which outcome results when encoder signals drift within a robotic arm's PID control loop?
• Which risk increases when a refrigeration system's evaporator coil ices over completely due to uncontrolled heat influx?
• Which risk increases when the cooling load on a chiller causes prolonged low refrigerant flow rates?
• Which limitation arises when a delta-wye transformer bank supplying a balanced three-phase load experiences a single-phase transformer failure?
• Which risk increases when molten metal is introduced in gravity die casting without initial preheating?
• Which outcome occurs when rapid cylinder pressure increase induces ultrasonic waves?
