In addition, the air gap between the fibers causes a reflection when the light encounters the change n refractive index from the glass fiber to the air in the gap. This reflection (called fresnel reflection) amounts to about 5% in typical flat polished connectors, and means that no connector with an air gap can have less than 0.3 dB loss.

Blending, however, does chop fiber into smaller pieces. How this affects its activity in the body depends on what kind of fiber we're talking about. An article Lee dug up for me in The Journal of Food Science notes that grinding up wheat bran reduces its ability to hold water, which presumably decreases its effectiveness in promoting regularity.
