When an optical fiber is bent beyond its minimum bend radius, it can cause the fiber to fracture or break, leading to a complete loss of signal. This can occur when the fiber is subjected to a tight bend, such as when it is wrapped around a small diameter object or when it is bent. Although fibre optic cables have a certain flexibility, they cannot be bent every which way without consequences. The tighter the bend, the greater the losses, and the more significant the impact on signal quality. This difference makes fiber much more sensitive to physical damage, as light cannot navigate a broken or sharply bent pathway easily. When you experience a sudden drop in internet performance or a complete service outage, the fragile nature of the fiber cable entering your home is often the source. Yes, fiber cables can be bent during installation, which proves particularly useful when you pull cables into position rather than using blown installation methods.
