   Transducers and Infrastructure
   The conversion between electrical signals and optical signals is performed by active components. Light Emitting Diodes (LEDs) offer low-cost, wide-beam coupling, suitable for MMF{.MMF} systems, while Semiconductor Lasers (e.g., DFB or DBR lasers) provide the high spectral purity and power required for long-haul …
