Install and Remove QSFP+/QSFP28 Transceiver Modules
This section provides the installation, cabling, and removal instructions for the 40-Gigabit Quad Small
Form-Factor Pluggable Plus (QSFP+) and 100 Gigabit (QSFP28) transceiver modules. The modules are
hot-swappable input/output (I/O) devices that connect the system’s module port electrical circuitry with either
a copper or a fiber-optic network.
The following figure shows the 40-Gigabit optical QSFP+ transceiver. The transceiver is used primarily in
short reach applications in switches, routers, and data center equipment where it provides higher density than
SFP+ modules. The 100-Gigabit optical QSFP28 transceiver is similar to the 40-Gigabit optical QSFP
transceiver.

Overview
The 40-Gigabit (GE) QSFP+ and 100 Gigabit (QSFP28) transceiver module is a hot-swappable, parallel
fiber-optical module with 4 independent optical transmit and receive channels. These channels can terminate
in another 40-Gigabit QSFP+ transceiver, or the channels can be broken out to 4 separate 10-Gigabit SFP+
transceivers. The QSFP+ transceiver module connects the electrical circuitry of the system with an optical
external network.
The following figure shows the 40-Gigabit optical QSFP+ transceiver. The transceiver is used primarily in
short reach applications in switches, routers, and data center equipment where it provides higher density than
SFP+ modules. The 100-Gigabit optical QSFP28 transceiver is similar to the 40-Gigabit optical QSFP
transceiver.
