Q
What is Dell Networking Compatible SFP28?
A
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.
Q
Which devices support Dell Networking Compatible SFP28?
A
These SFP28 modules are compatible with Dell PowerSwitch and N-series switches that have SFP28 uplink ports and firmware supporting third-party optics.
Q
What fiber types and distances are supported by this module?
A
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.
Q
Is Dell Networking Compatible SFP28 rated for 25 Gbps?
A
Yes. It fully supports 25 Gb/s data transmission in accordance with IEEE 802.3by standards.
Q
Can I mix Dell Networking Compatible SFP28 modules with other brands?
A
Yes. As an MSA-compliant transceiver, it can interoperate with any vendor’s SFP28 ports provided the switch firmware allows third-party optics.
Q
Are Dell Networking Compatible SFP28 modules hot-swappable?
A
Yes. You can insert or remove the module without powering down the host device, ensuring uninterrupted network operations.
Q
Does this module support digital diagnostics monitoring (DDM/DOM)?
A
Yes. It includes a digital diagnostics interface that provides real-time monitoring of temperature, optical power, and transceiver voltage.
Q
How do I install a Dell Networking Compatible SFP28 in my switch?
A
Power on the switch, remove the dust cover, insert the SFP28 module until it clicks, then connect the fiber cable—no reboot is required.
Q
What is the difference between SFP28 and SFP+ modules?
A
SFP28 doubles the data rate of SFP+ from 10 Gb/s to 25 Gb/s while retaining the same form factor and MSA footprint.
Q
Does the module work with both single-mode and multimode fiber?
A
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.
Q
How can I verify compatibility before purchase?
A
Check your Dell switch’s technical specifications for supported optic lists or use Dell’s support matrix to confirm third-party SFP28 compatibility.
Q
What warranty covers Dell Networking Compatible SFP28 modules?
A
Most vendors offer a one-year limited warranty covering defects in materials and workmanship under normal use.
Q
How do I troubleshoot a module that isn’t detected?
A
Ensure the transceiver is fully seated, verify firmware supports third-party optics, check fiber polarity, and inspect diagnostic logs for errors.
Q
Can Dell Networking Compatible SFP28 be used with direct attach copper (DAC) cables?
A
No. SFP28 DAC cables use a different electrical interface and are sold as integrated copper assemblies, not fiber transceivers.
Q
What are the operating temperature and power specifications?
A
Typical operating range is 0 °C to 70 °C, with power consumption under 1 W, compliant with Dell switch power budgets.
Q
How do I order genuine Dell Networking Compatible SFP28 modules?
A
Purchase from authorized optics resellers or online marketplaces that specify Dell Networking compatibility and provide warranty coverage.
