Quick Answer: Loose tube fiber is the standard for outside plant (OSP) applications — underground conduit, direct buried, and aerial runs — because it handles moisture, temperature swings, and high pulling tension. Losses can be introduced by various means such as intrinsic material absorption, scattering, bending, connector loss and more. This article will delve into the. Fiber loss, or attenuation, refers to the reduction in optical power as light travels through a fiber optic cable. While some loss is expected, excessive or unexpected loss can lead to poor performance, network downtime, and signal failure.
