cable
NOTE: If you are configuring a port as multiple
10-Gigabit Ethernet interfaces, you can use a
fiber breakout cable to distribute the interfaces
to up to four 10GBASE-SR SFP+ transceivers.
QSFP+ module 40GBASE-eSR4, 40-Gigabit
Ethernet QFX-QSFP-40G-ESR4
1310 nm for up to 10 km on SMF QSFP+ module 40GBASE-LR4, 40-Gigabit
Ethernet pluggable JNP-QSFP-40G-LR4
Table 21 on page 60 describes the supported DAC and DAC breakout cables.
CAUTION: You can use DAC and DAC breakout cables purchased from a third
party at your own risk. If there is a problem with the cable, support will not
be provided. If you choose to use a third-party cable, it should meet the
specifications described in
“Interface Specifications for SFP+ DAC Cables
for the QFX Series” on page 73 , “Interface Specifications for QSFP+ DAC
Breakout Cables for the QFX Series” on page 79 , and “Interface Specifications
for QSFP+ DAC Cables for the QFX Series” on page 82 .
