Definitely strong and lasting for a good amount of time, it only takes a dab to be wrapped in your favorite Scentsy scent! If you are in love with one of the scents that Scentsy offers it's perfume in (and I definitely recommend that you love it), you will enjoy this!! Bath and Body Works doesn't make anything like it.
Using a lens, the light pulses are funneled into the fiber-optic medium where they travel down the cable. The light (near infrared) is most often 850nm for shorter distances and 1,300nm for longer distances on Multi-mode fiber and 1300nm for single-mode fiber and 1,500nm is used for for longer distances.
Because of its advantages over electrical transmission, optical fibers have largely replaced copper wire communications in core networks in the developed world. Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals.Due to much lower attenuation and interference, optical fiber has large advantages over existing copper wire in long-distance and high-demand applications.ptical fiber was successfully developed in 1970 by Corning Glass Works, with attenuation low enough for communication purposes (about 20 dB /km), and at the same time GaAs semiconductor lasers were developed that were compact and therefore suitable for transmitting light through fiber optic cables for long distances.
