Morphology
fiber + optic + microphone
The phrase is compositionally transparent: 'fiber' (light-carrying strand) + 'optic' (relating to optical/light technology) modifies 'microphone' (sound sensor), so the meaning of a microphone that uses fiber-optic/optical methods is directly predictable. The collocation 'fiber optic' is a common technological compound across languages, so a B1 learner who knows the constituents would likely infer the intended device.
Etymology
The noun fiber optic microphone comes from its parts: a thin glass fiber that carries light, the optic part, and a microphone that 'hears' sound. When sound moves the glass, the light inside changes and the device turns that change into a signal, so it 'hears' using light instead of electrical parts, and that's why it works well near strong electrical noise.
