Fiber can go around corners, but it should not be folded into a sharp ninety-degree bend. Bend-insensitive fiber and armored cable reduce particular risks without eliminating the need to follow product specifications.<\/p><p>Pre-terminated assemblies remove field splicing and termination from the job site.
