Question 1

What is Dell Networking Compatible SFP28?

Accepted Answer

Dell Networking Compatible SFP28 is a third-party, IEEE 802.3by-compliant 25 Gb/s small form-factor pluggable module designed for Dell network switches and routers.

Question 2

Which devices support Dell Networking Compatible SFP28?

Accepted Answer

These SFP28 modules are compatible with Dell PowerSwitch and N-series switches that have SFP28 uplink ports and firmware supporting third-party optics.

Question 3

What fiber types and distances are supported by this module?

Accepted Answer

For multimode fiber (OM3/OM4) it supports up to 100 m, and for single-mode fiber it supports up to 10 km at 25 Gb/s data rates.

Question 4

Is Dell Networking Compatible SFP28 rated for 25 Gbps?

Accepted Answer

Yes. It fully supports 25 Gb/s data transmission in accordance with IEEE 802.3by standards.

Question 5

Can I mix Dell Networking Compatible SFP28 modules with other brands?

Accepted Answer

Yes. As an MSA-compliant transceiver, it can interoperate with any vendor’s SFP28 ports provided the switch firmware allows third-party optics.

Question 6

Are Dell Networking Compatible SFP28 modules hot-swappable?

Accepted Answer

Yes. You can insert or remove the module without powering down the host device, ensuring uninterrupted network operations.

Question 7

Does this module support digital diagnostics monitoring (DDM/DOM)?

Accepted Answer

Yes. It includes a digital diagnostics interface that provides real-time monitoring of temperature, optical power, and transceiver voltage.

Question 8

How do I install a Dell Networking Compatible SFP28 in my switch?

Accepted Answer

Power on the switch, remove the dust cover, insert the SFP28 module until it clicks, then connect the fiber cable—no reboot is required.

Question 9

What is the difference between SFP28 and SFP+ modules?

Accepted Answer

SFP28 doubles the data rate of SFP+ from 10 Gb/s to 25 Gb/s while retaining the same form factor and MSA footprint.

Question 10

Does the module work with both single-mode and multimode fiber?

Accepted Answer

No. You must select the appropriate SKU: an SR version for multimode fiber (OM3/OM4) and an LR version for single-mode fiber up to 10 km.

Question 11

How can I verify compatibility before purchase?

Accepted Answer

Check your Dell switch’s technical specifications for supported optic lists or use Dell’s support matrix to confirm third-party SFP28 compatibility.

Question 12

What warranty covers Dell Networking Compatible SFP28 modules?

Accepted Answer

Most vendors offer a one-year limited warranty covering defects in materials and workmanship under normal use.

Question 13

How do I troubleshoot a module that isn’t detected?

Accepted Answer

Ensure the transceiver is fully seated, verify firmware supports third-party optics, check fiber polarity, and inspect diagnostic logs for errors.

Question 14

Can Dell Networking Compatible SFP28 be used with direct attach copper (DAC) cables?

Accepted Answer

No. SFP28 DAC cables use a different electrical interface and are sold as integrated copper assemblies, not fiber transceivers.

Question 15

What are the operating temperature and power specifications?

Accepted Answer

Typical operating range is 0 °C to 70 °C, with power consumption under 1 W, compliant with Dell switch power budgets.

Question 16

How do I order genuine Dell Networking Compatible SFP28 modules?

Accepted Answer

Purchase from authorized optics resellers or online marketplaces that specify Dell Networking compatibility and provide warranty coverage.
