Cable Specifications for QSFP+ and QSFP28 Transceivers
The 40-Gigabit Ethernet QSFP+ and 100-Gigabit Ethernet QSFP28 transceivers that are used in QFX
Series switches use 12-ribbon multimode fiber crossover cables with socket MPO/UPC connectors. The
fiber can be either OM3 or OM4. These cables are not sold by Juniper Networks.
CAUTION:
To maintain agency approvals, use only a properly constructed, shielded
cable.
TIP:
Ensure that you order cables with the correct polarity. Vendors refer to these crossover
cables as key up to key up, latch up to latch up, Type B, or Method B. If you are using patch panels
between two QSFP+ or QSFP28 transceivers, ensure that the proper polarity is maintained
through the cable plant.
