Table 16 on page 44 lists the specifications for the cables that connect the QFX Series
to a management device.
NOTE: The QFX Series can be configured with SFP management ports that
support 1000BASE-SX transceivers. See “Interface Specifications for SFP,
SFP+, and QSFP+ Transceivers for the EX4600 Switch” on page 49 for more
information about the fiber-optic cables required for use with these
transceivers.

Understanding EX Series Switches 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.
EX Series Switches use various types of network cable, including multimode and
single-mode fiber-optic cable.

Attenuation and Dispersion in Fiber-Optic Cable on page 75
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). Interfaces with multimode optics typically use LEDs
