The Multiple-fiber Push-On (MPO) connectors on the optical QSFP+, QSFP28, or QSFP-DD 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+, QSFP28, or QSFP-DD transceivers do not support
network interface cables with an angle-polished contact (APC) face type.
Note
To attach the optical network cable:
1.
Remove the dust plugs from the optical network interface cable MPO connectors. Save the dust plugs for
future use.
2.
Inspect and clean the MPO connector’s fiber-optic end faces.
3.
Remove the dust plugs from the transceiver module optical bores.
4.
Immediately attach the network interface cable MPO connectors to the transceiver module.
Removing the 40-Gigabit QSFP+, 100-Gigabit QSFP28, or
200/400-Gigabit QSFP-DD Transceiver Module
The QSFP+, QSFP28, or QSFP-DD transceiver module is a static-sensitive device. Always use an ESD wrist
strap or similar individual grounding device when handling QSFP+ or QSFP28 transceiver modules or when
coming into contact with modules.
Caution
To remove a QSFP+, QSFP28, or QSFP-DD transceiver module:
• For transceiver modules, disconnect the network interface cable from the transceiver connector.
• For transceiver modules equipped with a bale clasp latch:
1.
Pivot the bale clasp down to the horizontal position.
2.
Immediately install the dust plug into the transceivers optical bore.
3.
Grasp the sides of the transceiver and slide it out of the module socket.
• For transceivers equipped with a pull tab latch:
1.
Immediately install the dust plug into the transceiver’s optical bore.
2.
Grasp the tab and gently pull to release the transceiver from the socket.
3.
Slide the transceiver out of the socket.
