How to Install a QSFP28 Transceiver

In recent years, QSFP28 transceivers have been highly favored by many Ethernet users. The modules are hot-swappable input/output (I/O) device that connect the system’s module port electrical circuity with either a copper or a fiber-optic network. Transceiver installation attaches great importance to the whole Ethernet connectivity. This article provides the installation tips of 100 Gigabit QSFP28 optical transceivers.

Information About QSFP28 Transceiver

100 Gigabit (QSFP28) transceiver module is a hot-swappable, parallel fiber-optical module. The interconnect offers four channels of high-speed differential signals with data rates ranging from 25 Gbps up to potentially 40 Gbps, and will meet 100 Gbps Ethernet (4×25 Gbps) and 100 Gbps 4X InfiniBand Enhanced Data Rate (EDR) requirements. These channels can terminate in another 40G QSFP+ transceiver. The QSFP+ transceiver connects the electrical circuity of the system with an optical external network.

The following figure shows the 100G QSFP28 SR4 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.

Required Tools and Equipment

To install the 100G QSFP28 transceiver, you need the following tools :

    • 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.

The QSFP28 transceiver can have either a bail-clasp latch or a pull-tab latch. Installation procedures for both types of latches are provided.

Caution: The QSFP28 transceiver is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling QSFP28 transceivers or coming into contact with system modules.

Installation Steps:

Step1: Attach an ESD wrist strap to yourself and a properly grounded point on the chassis or the rack.

Step2: Remove the QSFP28 transceiver from its protective packaging.

Step3: Check the label on the QSFP28 transceiver body to verify that you have the correct model for your network.

Step 4: For QSFP28 transceiver, remove the optical bore dust plug and set it aside.

Step 5: For QSFP28 transceiver equipped with a pull-tab, hold the transceiver so that the identifier label is on the top.

Step 6: For QSFP28 transceiver equipped with a bail-clasp latch, keep the bail-clasp aligned in a vertical position.

Step 7: Align the QSFP28 transceiver in front of the transceiver’s socket opening and carefully slide the QSFP28 transceiver into the socket until the transceiver makes contact with the socket electrical connector (see the figure below).

Step8: Press firmly on the front of the QSFP28 transceiver with your thumb to fully seat the transceiver in the module’s transceiver socket (see the below figure).

Caution: If the latch is not fully engaged, you might accidentally disconnect the QSFP28 transceiver.
