  • Page 71 To determine the power budget and power margin needed for fiber-optic connections, you need to understand how signal loss, attenuation, and dispersion affect transmission. EX Series switches use various types of network cables, including multimode and single-mode fiber-optic cable. Signal Loss in Multimode and Single-Mode Fiber-Optic Cable Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber).

  • Page 72: Calculate The Fiber-Optic Cable Power Budget For Ex Series Devices

    For single-mode transmission, modal dispersion is not a factor. However, at higher bit rates and over longer distances, chromatic dispersion limits the maximum link length. An efficient optical data link must have enough light to exceed the minimum power that the receiver requires to operate within its specifications.
