The 40-Gigabit Ethernet QSFP+ and 100-Gigabit Ethernet QSFP28 transceivers that are
used in QFX Series and EX4600 switches use 12-ribbon multimode fiber crossover cables
with female 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.
Table 30 on page 82 describes the signals on each fiber.
