DWDM

  DWDM – Detailed Technical Explanation for Interview Preparation 1. What is DWDM? DWDM (Dense Wavelength Division Multiplexing) is an optical transmission technology that allows multiple data channels to be carried simultaneously over a single optical fiber by using different wavelengths (colors) of laser light. It significantly increases bandwidth capacity without deploying more fiber, making it ideal for large-scale, high-capacity networks like Safe City infrastructures, ISPs, telcos, and data centers. 2. Key Concept A single fiber can carry 40, 80, 96, or even 192 wavelengths , with each wavelength transporting 1G, 10G, 40G, 100G, or higher data rates. DWDM = Multiple wavelengths + Single fiber + Long distance + High capacity. 3. How DWDM Works (Core Working Principle) Multiple Signals → Mux Client signals (Ethernet, SDH, MPLS, IP, Fibre Channel) are converted to optical signals and combined using a MUX (multiplexer). Transmission Over Fiber All wavelengths tr...
