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.
Overview
The 40-Gigabit (GE) QSFP+ and 100 Gigabit (QSFP28) transceiver module is a hot-swappable, parallel
fiber-optical module with four independent optical transmit and receive channels. These channels can terminate
in another 40-Gigabit QSFP+ transceiver, or the channels can be broken out to four 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

Required Tools and Equipment
You need these tools to install the 40-Gigabit QSFP+ / 100-Gigabit QSFP28 transceiver modules:
• Wrist strap or other personal grounding device to prevent ESD occurrences.
• Antistatic mat or antistatic foam to set the transceiver on.
• Fiber-optic end-face cleaning tools and inspection equipment.
For complete information on inspecting and cleaning fiber-optic connections, see Cleaning Fiber-Optic
Connectors, on page 133.
Installing the 40-Gigabit QSFP+ or 100-Gigabit Transceiver Module
The QSFP+ or QSFP28 transceiver module can have either a bail-clasp latch or a pull-tab latch. Installation
procedures for both types of latches are provided.
