Page 107 Signal Loss in Multimode and Single-Mode Fiber-Optic Cables Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber). Interfaces with multimode optics typically use LEDs as light sources. However, LEDs are not coherent light sources.
Page 108: Calculating Power Budget And Power Margin For Fiber-Optic Cables
TIP: You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on your Juniper Networks device. To calculate the power budget and power margin, perform the following tasks: How to Calculate Power Budget for Fiber-Optic Cables To ensure that fiber-optic connections have sufficient power for correct operation, you need to calculate the link's power budget, which is the maximum amount of power it can transmit.
Page 109: How To Calculate Power Margin For Fiber-Optic Cables
– P = –15 dBm – (–28 dBm) = 13 dB How to Calculate Power Margin for Fiber-Optic Cables After calculating a link's power budget, you can calculate the power margin (P ), which represents the amount of power available after subtracting attenuation or link loss (LL) from the power budget (P ).
Page 110 In both examples, the calculated power margin is greater than zero, indicating that the link has sufficient power for transmission and does not exceed the maximum receiver input power. RELATED DOCUMENTATION QFX5100 Chassis Description and Port Panels | 19 QFX5100 Power System | 53...

Step 1 of the following procedure. • Phillips (+) screwdriver, number 2 The QFX5100-24Q device allows up to two expansion modules to be added to the port panel to increase port density. The QFX5100-24Q device holds two bays of expansion modules that can be mixed and matched as desired.
Page 168 Figure 83: EX4600-EM-8F Expansion Module The QFX5100-24Q device is configured for the QFX-EM-4Q by default, but any combination of the two modules is supported. Expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-8F is inserted instead of the default QFX-EM-4Q, the new configuration causes the PFE to reboot and all of the interfaces to go down temporarily, causing a short disruption in traffic.
Page 169 6. Raise the handle and tighten the captive screws by using your fingers or the screwdriver. For the QFX5100-24Q-AA, retract the ejector handles and tighten the captive screws by using your fingers or the screwdriver (see Figure 86 on page 161).

NOTE: When you install the QFX-PFA-4Q expansion module in a QFX5100-24Q-AA switch and reboot the switch, the two NIC ports in the NIC inside the QFX5100-24Q-AA switch are enabled automatically. When you install other expansion modules (QFX-EM-4Q or EX4600-EM-8F), the NIC ports are enabled only when an EX4600-EM-8F is installed in slot 2 (QIC1), that is, the expansion module slot located on your right as you face the QFX5100-24Q-AA.
