Dell 407-BCBF Compatible 25GBASE-SR SFP28 Intel Customer Kit for PowerEdge Servers

EdgeOptic's 407-BCBF compatible is a Dell-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor SFP28 dual-rate 10G/25G SR transceiver. 407-BCBF is Dell's Customer Kit ordering code for the 25GbE SFP28 SR optic shipped with Intel 25GbE adapters on Dell PowerEdge server platforms, published on Dell.com as 'Dell SFP28 SR Optical Transceiver 25GbE, Intel, Customer Kit'. The module is programmed with Dell-recognized EEPROM vendor and part-number strings so PowerEdge iDRAC and the host's Intel 25GbE driver stack read the optic cleanly through the standard SFP28 management interface.

Optical behavior is 25GBASE-SR per IEEE 802.3by Clause 112 over duplex multi-mode fiber. Line signaling rate is 25.78125 Gbps at 25GBASE-SR; 10GBASE-SR signaling at 10.3125 Gbps per IEEE 802.3ae is supported on dual-rate SFP28 host ports. Reach is 100 m on OM4 and 70 m on OM3, within the SFP28 SerDes envelope defined by SFP28 MSA SFF-8402.

Optical path is 850 nm VCSEL transmitter, PIN photodiode receiver, TX optical power −5 to +2.4 dBm, RX sensitivity better than −10.3 dBm, 5.3 dB link budget, LC duplex connector. Digital diagnostics are SFF-8472 Rev 12.0 compliant, exposing per-module temperature, supply voltage, TX bias, TX power and RX power through iDRAC's transceiver-diagnostics interface and through standard Linux ethtool access on the host. Power dissipation is 0.3 W, the module is hot-swappable, and the operating temperature range is 0 to 70°C commercial.

407-BCBF is positioned against Dell PowerEdge server platforms with Intel 25GbE SFP28 adapters. Verify 407-BCBF against the Dell PowerEdge transceiver compatibility documentation for your specific server model and BIOS/iDRAC release before specifying the part. Adjacent Dell ordering codes worth knowing during procurement: 407-BBXU is the Dell PowerSwitch 25GbE SFP28 SR variant titled 'No FEC, MMF' on Dell.com, a switch-fabric ordering code distinct from the PowerEdge Customer Kit; 407-BBWK is Dell's standard PowerSwitch 25GbE SFP28 SR. Match the SKU to your Dell quote or BOM.

On FEC, 25G FEC mode is configured at the MAC layer on each link partner and the optical path is agnostic to whether RS-FEC per IEEE 802.3by Clause 108 or BASE-R FEC is negotiated on the host. The Intel adapter's FEC profile and the link-partner switch FEC profile determine the negotiated mode on the link; confirm the FEC profile on both ends during commissioning to avoid mismatch on mixed-vendor 25G interconnects. The module is symmetrically compatible with either FEC mode supported on the host port.

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