How light travels in multimode fiber

by Fiber-MART.COM The most important component affecting loss in a multimode cable plant is the source-coupling light into the fiber. Light sources may be light-emitting diodes (LEDs) or lasers. Lasers may be VCSELs (vertical cavity surface-emitting lasers) or Fabry-Perot lasers (telecom style). Each of these emits light in a different pattern, with [ Continue reading…]
