Grasp the MPO connector only by the housing to plug or unplug a fiber-optic cable.
40-Gigabit QSFP+ or QSFP28 transceiver modules are keyed to prevent incorrect insertion.
Note
The multiple-fiber push-on (MPO) connectors on the optical QSFP+ or QSFP28 transceivers support
network interface cables with either physical contact (PC) or ultra-physical contact (UPC) flat polished
face types. The MPO connectors on the optical QSFP+ or QSFP28 transceivers do not support network
interface cables with an angle-polished contact (APC) face type.
Note
Step 1
Remove the dust plugs from the optical network interface cable MPO connectors. Save the dust plugs for future use.
Step 2
Inspect and clean the MPO connector
’
s fiber-optic end faces.
Step 3
Remove the dust plugs from the QSFP+ or QSFP28 transceiver module optical bores.
Step 4
Immediately attach the network interface cable MPO connectors to the QSFP+ or QSFP28 transceiver module (see the
figure below).
