A motto, emblem, or other mark used to distinguish the bearer from others. A device differs from a badge or cognizance primarily because as it is a personal distinction, and not a badge borne by members of the same house successively. device(Noun) An image used in whole or in part as a trademark or service mark.
When testing per FOTP-171 (single ended), include only one connector-the one atached to the launch cable. Splice Loss. For each splice, figure 0.3 dB (0.3 max per EIA/TIA 568). Fiber Loss. For multimode fiber, the loss is about 3 dB per km for 850 nm sources, 1 dB per km for 1300 nm.(3.5 and 1.5 dB/km max per EIA/TIA 568) This roughly translates into a loss of 0.1 dB per 100 feet (30 m) for 850 nm, 0.1 dB per 300 feet(100 m) for 1300 nm.hen testing per FOTP-171 (single ended), include only one connector-the one atached to the launch cable.

When light traveling in the fiber core radiates into the fiber cladding, higher-order mode loss results. Together these factors limit the transmission distance of multimode fiber compared with single-mode fiber. Single-mode fiber is so small in diameter that rays of light can reflect internally through one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber. Compared with multimode fiber, single-mode fiber has higher bandwidth and can carry signals for longer distances. Exceeding the maximum transmission distances can result in significant signal loss, which causes unreliable transmission. Attenuation and Dispersion in Fiber-Optic Cable
