5. Digital techniques / Electronic instrument systems

What is the advantage of an ILD over an LED when used as a light source in fibre optics?

Lower frequency range.
Greater power output.
Wider frequency output.

Explanation from PART66Online

An injection laser diode (ILD) provides greater optical power output than an LED, along with narrower spectral width and faster modulation, letting it drive longer, higher-rate links. Its frequency range is narrower, not wider, so the power advantage is the key benefit over an LED source.
