Dell (Force10) compatible D2VX1 Description
EdgeOptic's D2VX1 compatible is a Dell-coded 25GBASE-SR SFP28 transceiver built as a direct replacement for the Dell D2VX1. It ships with Dell-recognized EEPROM so Dell PowerEdge servers and Dell iDRAC firmware identify the optic as a native Dell part, and the Mellanox ConnectX adapters the D2VX1 is commonly paired with read the module through standard SFF-8472 access.
Optical behavior is 25GBASE-SR per IEEE 802.3by Clause 112 over duplex multi-mode fiber: 100m on OM4 or OM5, 70m on OM3. Line signaling rate is 25.78125 Gbd, with dual-rate support from 8.5 to 25.78 Gbps for 10GBASE-SR downshift on mixed-speed infrastructure. Transmit power is -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, link budget 5.3 dB with host RS-FEC per IEEE 802.3by Clause 108. Duplex LC/UPC, DOM per SFF-8472, 0.3W typical power. Operating case temperature is 0 to 70 degrees Celsius.
D2VX1 is the Dell configure-to-order part number for the 25GbE SFP28 SR optic that ships with Mellanox ConnectX adapter builds on Dell PowerEdge servers. It sits in a different procurement path from the Dell PowerSwitch optics: 407-BBXU is the switch-port No FEC module, SFP28-25G-SR is the switch-native OS10 ordering code, and 407-BCBF is the Intel Customer Kit for Intel 25GbE adapter builds. D2VX1 is the Mellanox-adapter path, ordered against the server SKU rather than a switch-port line.
Platform scope is the Dell PowerEdge R-series chassis family carrying Mellanox ConnectX-4 Lx and ConnectX-5 25GbE adapter options (rack servers from the R440, R540, R640, R740, R840 generations through the R750 and later where Mellanox ConnectX remains an adapter SKU). The optic also works as a standard 25GBASE-SR SFP28 in any Dell PowerSwitch port that meets the 25G SFP28 electrical specification, though for switch-side procurement the 407-BBXU or SFP28-25G-SR ordering paths are the Dell-native route.
DOM registers for transmit power, receive power, supply voltage, laser bias and module temperature are exposed through SFF-8472 and accessible via iDRAC storage and networking telemetry, via the Mellanox ConnectX driver stack (mlxlink on Linux, or via standard ethtool output on Linux hosts); Windows host DOM access depends on the driver version, so confirm with your Mellanox/NVIDIA driver documentation. Every unit is factory-tested to the 25GBASE-SR optical specification per IEEE 802.3by Clause 112 before dispatch.

Frequently Asked Questions
What is the difference between Dell D2VX1, 407-BBXU and 407-BCBF?
The three part numbers cover different Dell procurement paths for the same 25GBASE-SR optical specification. D2VX1 is the configure-to-order SFP28 that ships with Mellanox ConnectX adapter builds on Dell PowerEdge servers. 407-BCBF is the Intel Customer Kit, shipped with PowerEdge builds using Intel 25GbE adapters. 407-BBXU is the Dell Networking switch-port module, labelled No FEC, ordered against PowerSwitch line cards. Optically they are interchangeable 25GBASE-SR SFP28 modules; the EEPROM coding and Dell procurement context differ.
Which Dell PowerEdge servers and adapters originally ship with the D2VX1?
D2VX1 is the CTO SFP28 ordered with Mellanox ConnectX-4 Lx and ConnectX-5 25GbE adapter builds across the Dell PowerEdge R-series rack-server family, covering R440, R540, R640, R740 and R840 generations through the R750 era and later where Mellanox ConnectX remains an offered adapter SKU. For the exact PowerEdge-to-adapter matrix at your generation, verify against the Dell PowerEdge configuration guide for the chassis; EdgeOptic can supply a sample for pre-deployment qualification.
Does the D2VX1 support dual-rate 10G and 25G operation on mixed-speed server NIC deployments?
Yes. The module supports line rates from 8.5 to 25.78 Gbps, which covers 10GBASE-SR at 10.3125 Gbd and 25GBASE-SR at 25.78125 Gbd. On a PowerEdge server carrying a ConnectX adapter, the rate is driven by the switch port or link-partner speed. This is useful during phased 10G-to-25G upgrades where a subset of access-layer ports still operate at 10G.
Can the D2VX1 be used in a Dell PowerSwitch 25G port instead of ordering 407-BBXU?
Optically the D2VX1 is a standard 25GBASE-SR SFP28 and works in any compliant SFP28 port. Dell's own procurement and support pathway for PowerSwitch 25G ports is 407-BBXU or SFP28-25G-SR, not D2VX1; using the server-NIC OPN in a switch port can complicate Dell ProSupport cases that key off the asset tag. For PowerSwitch deployments the cleaner choice is 407-BBXU or the EdgeOptic-compatible SFP28-25G-SR.
