What are the benefits of lightning protection for optical fiber lines
Implementing lightning protection strategies such as surge protection devices, grounding systems, lightning rods, and proper cable design can help safeguard fiber optic cables and the networks they support. Lightning-induced surges can travel through power lines, telecommunication lines, or nearby metallic structures and pose a. Lightning protection is one of the key reasons for utilizing fiber optics.

Dual-mode optical module switches can be used
Short answer: Usually yes, you use them in pairs, but the “pair” can be a media converter on one end and a fiber switch (or SFP in a switch) on the other, as long as both sides speak the same speed, wavelength, and optical mode. Dual fiber modules use two fibers. They are easier to set up and give steady communication. But one topic causes constant confusion: single-fiber vs dual-fiber designs.
