Dell (Force10) compatible Q28-100G-LR4 Description

EdgeOptic's Q28-100G-LR4 compatible is a Dell-coded 100GBASE-LR4 QSFP28 transceiver for Dell Force10 and Dell EMC Networking switches running OS9. The Q28- prefix is the Force10 and OS9-era ordering code for QSFP28 optics, predating the Dell EMC PowerSwitch unification. The Gen3 PowerSwitch generation uses the 407-BCDH ordering code on a separate part. Reach is 10 km over single-mode fiber with a guaranteed 6.3 dB link budget, an LC duplex connector, and DOM diagnostics readable from the host.

The optical engine uses an EML transmitter and PIN photodiode receiver across the four LAN WDM lanes at 1295.56, 1300.05, 1304.58 and 1309.14 nm. Aggregate line rate is 103.125 Gbps (4 by 25.78125 Gbps NRZ), aligned to the IEEE 802.3ba Clause 88 100GBASE-LR4 specification and the SFF-8665 QSFP28 MSA. Operating temperature range is 0 to 70 C for commercial deployments.

Compatible with Dell PowerSwitch Z9100-ON and S6100-ON families running OS9; the Z9100-ON ships with 32 QSFP28 cages provisioned for 100G, including 100GBASE-LR4. Verify against the Dell PowerSwitch transceiver matrix for your specific switch model and OS9 release. EdgeOptic's compatible carries Dell-recognized EEPROM so the module enumerates and operates on these platforms without configuration overrides. Q28-100G-LR4-G3 is a separate Gen3 part number; do not substitute it for the original Q28-100G-LR4 ordering code without confirming the EEPROM expectation on the target switch.

Typical deployments include data center fabric uplinks, ToR-to-spine interconnects and metro 100G backbone runs where the 10 km LR4 reach matches inter-building fiber spans. The compatible meets CE and RoHS, ships with the same optical performance envelope as the Dell OEM equivalent, and supports DOM polling for live link-budget visibility. For ordering questions, fiber-plant validation or larger-volume quotes, contact our sales team.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.

Frequently Asked Questions

Which Dell switches accept the Q28-100G-LR4?

Compatible with Dell PowerSwitch Z9100-ON and S6100-ON family chassis running OS9. The Z9100-ON in particular provides 32 QSFP28 cages for 100GBASE-LR4 and other 100G reach classes. Verify against the Dell PowerSwitch transceiver matrix for your specific switch model and OS9 release.

Is Q28-100G-LR4 the same as 407-BCDH?

Both Dell ordering codes describe a 100GBASE-LR4 10 km QSFP28 transceiver, but they belong to different ordering generations. Q28-100G-LR4 is the Force10 and OS9-era code; 407-BCDH is the Gen3 PowerSwitch code that replaced it. The two SKUs are EEPROM-coded for their respective switch generations and are not interchangeable as drop-in replacements; pick the ordering code that matches the original Dell part on the target switch.

What is the difference between Q28-100G-LR4 and Q28-100G-LR4-G3?

Q28-100G-LR4-G3 is the Gen3 variant of the Q28-100G-LR4 line. The optical specification is the same 100GBASE-LR4 10 km class, but the EEPROM and platform expectations were refreshed for the Gen3 PowerSwitch generation. The original Q28-100G-LR4 ordering code targets the earlier OS9-era switch fleet. Use the part number that matches the Dell device's expected EEPROM.

Does the compatible Q28-100G-LR4 work on Z9100-ON running OS9?

Yes. The Z9100-ON OS9 platform recognizes Q28- ordering-code optics, and EdgeOptic's compatible ships with Dell-recognized EEPROM so the module enumerates without configuration overrides. Verify the OS9 release on the target switch supports the QSFP28 cage you plan to populate before deploying.
