Complete Hardware Guide for EX8208 Ethernet Switches Understanding EX8200 Switch Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion 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. Juniper Networks EX8200 Ethernet Switches use various types of network cable, including multimode and single-mode fiber-optic cable.
PAGE 133
Chapter 6: Cable Requirements • Modal dispersion, which is the spreading of the signal over time caused by the different propagation modes in the fiber. For multimode transmission, modal dispersion, rather than chromatic dispersion or attenuation, usually limits the maximum bit rate and link length. 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.

PAGE 143
Chapter 7: Planning Power Requirements To calculate the system thermal output: 1. Determine the maximum system power consumption of your switch in watts. See “Calculating the Power Consumption of Your EX8208 Switch Configuration” on page 115 for how to do so. 2. Multiply the maximum system power consumption by 3.41.
PAGE 144
Complete Hardware Guide for EX8208 Ethernet Switches To calculate the number of power supplies required for your switch configuration: Determine the power requirement of the base chassis (that is, the combined power requirements of the fan tray, SRE module or modules, and the SF module) by consulting Table 50 on page 118. 1. The watt values shown in Table 50 on page 118 are the amount of power reserved by power management for the chassis in its power budget.
PAGE 145
Chapter 7: Planning Power Requirements 3. Calculate the number of power supplies (N) required to meet the total power requirement by dividing the total power requirement by the output wattage of one power supply and then rounding up. NOTE: If the input is high-voltage line (200–220 VAC), the output wattage of a 2000 W AC power supply is 2000 W. If the input is low-voltage line (100–120 VAC), the output wattage of a 2000 W AC power supply is 1200 W.
