F5 Networks compatible F5-UPG-VEL-QSFP28-LR4 Description
EdgeOptic's F5-UPG-VEL-QSFP28-LR4 compatible is an F5-coded 100GBASE-LR4 QSFP28 transceiver built for the F5 VELOS chassis field-upgrade use case. The VEL designation in the part number marks this SKU as the VELOS-platform variant, distinct from the F5-UPG-QSFP28-LR4 module that targets F5 i-Series and VIPRION hardware. The module reaches 10 km over single-mode fiber with a guaranteed link budget of 6.3 dB, 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. Power-consumption figures are not published by F5 for this SKU; consult the F5 platform documentation if a strict power budget applies.
Per F5 TechDocs, F5-UPG-VEL-QSFP28-LR4 is listed as the field-upgrade transceiver for the VELOS BX110 and BX520 blades, plus the r5000, r10000 and r12000-DS appliances. On the BX520, only Port 1.0 accepts QSFP28 modules; Port 2.0 is QSFP-DD. F5 publishes a policy that only F5-branded optics are officially supported on VELOS (knowledge article K8153). EdgeOptic's compatible carries F5-recognized EEPROM so the module enumerates and runs in the host without configuration overrides; verify against the F5 platform transceiver list for your specific chassis revision.
Typical deployments include data center fabric uplinks, ADC-to-aggregation interconnects, and ISP backbone or metro aggregation links where the 10 km LR4 reach matches inter-DC building runs. The compatible meets CE and RoHS, ships with the same optical performance envelope as the F5 OEM equivalent, and supports DOM polling for live link-budget visibility.

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
Does the F5-UPG-VEL-QSFP28-LR4 work in both the BX110 and BX520 blades?
Yes on the BX110, which has two QSFP28 ports. On the BX520 only Port 1.0 accepts QSFP28; Port 2.0 is a QSFP-DD cage and will not accept this module. F5 TechDocs lists F5-UPG-VEL-QSFP28-LR4 for both blades plus the r5000, r10000 and r12000-DS appliances.
What is the difference between F5-UPG-VEL-QSFP28-LR4 and F5-UPG-QSFP28-LR4?
Both are 100GBASE-LR4 10 km QSFP28 modules from F5, but they target different platforms. The VEL prefix marks the VELOS field-upgrade variant for the BX110, BX520 and r-series appliances. F5-UPG-QSFP28-LR4 (without VEL) is the ordering code for F5 i-Series and VIPRION hardware. The two SKUs are not interchangeable, and EdgeOptic's compatibles are EEPROM-coded per SKU to match the F5 platform expectation.
Does F5 officially support third-party QSFP28 optics on VELOS?
F5's published policy (knowledge article K8153) is that only F5-branded optics are officially supported on VELOS. EdgeOptic's compatible is coded with F5-recognized EEPROM so the module enumerates and operates in the chassis without configuration overrides; the optic itself meets the same IEEE 802.3ba LR4 specification F5 publishes. For procurement situations that require strictly F5-branded parts, the OEM SKU is the right path.
Can the F5-UPG-VEL-QSFP28-LR4 be used in the r10000 and r12000-DS appliances?
Yes. F5 TechDocs lists r5000, r10000 and r12000-DS alongside the VELOS blades as accepted hosts for this SKU. The optical envelope is identical across these chassis; verify the QSFP28 cage assignment on your specific appliance revision before deployment.
