FS 100G QSFP28 and SFP-DD Transceiver Module
Audience:
This installation note provides instructions for installing FS Quad Small Form-factor Pluggable 28 (QSFP28) and Small Form-factor Pluggable Double Density (SFP-DD) transceiver modules. These modules are hotswappable input/output (I/O) devices that plug into 100GBASE ports, connecting the module to a fiber-optic or copper network.

Overview
Module Purpose and Instructions for Use
- QSFP28 and SFP-DD transceiver modules are hot-swappable I/O devices that can be plugged into module slots. These transceivers connect the module’s circuitry to the fiber-optic network.
- You can use any combination of QSFP28 and SFP-DD transceiver modules supported by FS devices. The only restriction is that each port must match the wavelength specifications of the other end of the fiber or cable, and the cable must not exceed the specified length to ensure reliable communication.
- Use only FS QSFP28 transceiver modules with your FS devices. Each QSFP28 transceiver module supports the FS Quality Identification (ID) feature, allowing the FS switch or router to identify and verify whether the transceiver module has been certified and tested by FS.
Module Appearance Overview
An optical QSFP28 transceiver module is shown in Figure 1.
An optical SFP-DD transceiver module is shown in Figure 2.

Safety
Required Tools
You will need the following tools to install the QSFP28 & SFP-DD transceiver modules:
- A wrist strap or other personal grounding device to prevent ESD occurrences.
- An antistatic mat or foam to place the transceiver on.
- Fiber-optic end-face cleaning tools and inspection equipment. For complete information on inspecting and cleaning fiber-optic connections, see the white paper at this URL: 5.1 Optical Module Endface Testing.
Installing QSFP28 and SFP-DD Transceiver Modules
Caution: QSFP28 and SFP-DD transceiver modules are static-sensitive devices. Always use an ESD wrist strap or a similar grounding device when handling or coming into contact with these modules.
To install an QSFP28 / SFP-DD transceiver module, please follow these steps:
- Step 1: Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.
- Step 2: Remove the QSFP28 / SFP-DD transceiver module from its protective packaging.
- Step 3: Check the label on the QSFP28 / SFP-DD transceiver module body to verify that you have the correct model for your network.
- Step 4: For optical QSFP28 or SFP-DD transceivers, remove the dust cap from the optical port and set it aside.
- Step 5: Hold the transceiver with the identifier label facing up. Align the QSFP28 or SFP-DD transceiver in front of the module transceiver socket opening, then carefully slide the transceiver into the socket until the transceiver contacts the electrical connector of the socket. (As shown in Figures 3 and 4.)
Step 7: For optical QSFP28 or SFP-DD modules, reinsert the dust plug into the transceiver’s optical port until you are ready to connect the network interface cable. Do not remove the dust plug until you are prepared to make the connection.
Connect Fiber Optic Network Cables
Before removing the dust plug and making any optical connections, please follow these guidelines:
- Keep the dust plug installed on the unconnected fiber cable connectors and transceiver optical ports until you are ready to make the connection.
- Inspect and clean the end faces of MPO / duplex LC connectors before making any connections. Refer to the tip after Step 2 in the next procedure for pointers to the fiber inspection and cleaning white paper.
- Insert or remove the fiber cable only by holding the MPO or duplex LC connector housing.
Caution: The MPO and duplex LC connectors on QSFP28 and SFP-DD transceivers support network interface cables with Physical Contact (PC) or Ultra Physical Contact (UPC) polished surface types. The MPO and duplex LC connectors on optical QSFP28 and SFP-DD transceivers do not support network interface cables with Angled Polished Contact (APC) surface types.
- Step 1: Remove the dust plug from the MPO connector of the fiber network interface cable. Please keep the dust plug in a safe place for future use.
- Step 2: Inspect and clean the fiber end face of the MPO or duplex LC connector. Refer to the tips below for a link to the fiber inspection and cleaning white paper.
Tips: For complete information on inspecting and cleaning fiber connections, please see this URL:
https://resource.fs.com/mall/resource/800g400g-transceiver-acceptance-testing-guide.pdf - Step 3: Remove the dust plug from the optical port of the QSFP28 or SFP-DD transceiver module.
- Step 4: Immediately connect the network interface cable MPO connector to the QSFP28 transceiver module ( Figure 7) or the duplex LC connector to the SFP-DD transceiver module ( Figure 8).
- Step 5: Gently pull on the MPO or duplex LC connector housing of the cable to check if the fiber network cable is fully seated. If the network cable is disconnected, reinstall it and ensure that the cable connector is fully seated and that the connector latch is engaged.
Removing QSFP28 and SFP-DD Transceiver Modules
Caution: QSFP28 and SFP-DD transceiver modules are electrostatic-sensitive devices. Always wear an ESD wrist strap or a similar personal grounding device when handling QSFP28 or SFP-DD transceiver modules or coming into contact with them.
To remove the QSFP28 or SFP-DD transceiver, follow these steps:
- Step 1: For optical QSFP28 or SFP-DD transceivers, disconnect the network interface cable from the QSFP28 or SFP-DD transceiver connector.
- Step 2: For QSFP28 or SFP-DD transceivers equipped with a pull-tab latch (see Figures 9 and 10, bottom view):
- Immediately install the dust plug into the transceiver’s optical port.
- Grasp the latch and gently pull to release the transceiver from the socket.
- Slide the transceiver out of the socket.
- Step 3: Place the QSFP28 or SFP-DD transceiver in an antistatic bag.
