Dell (Force10) WYMGJ Compatible 25GBASE-SR SFP28 for Dell PowerSwitch S5x00F-ON

EdgeOptic's WYMGJ compatible is a Dell (Force10)-coded 25GBASE-SR SFP28 transceiver built as a direct replacement for the Dell WYMGJ. It ships with Dell-recognized EEPROM vendor and part-number strings so Dell PowerSwitch S5x00F-ON series and PowerEdge platforms with 25G SFP28 interfaces identify the optic as a native Dell part. Link-up, receive-optical-signal and DOM telemetry surface through the host NOS on the standard optic-inventory path (OS10 Enterprise and SmartFabric OS10) without any vendor-override step.

Optical behavior is 25GBASE-SR per IEEE 802.3by Clause 112 over duplex multi-mode fiber: 100m on OM4, 70m on OM3. Line signaling rate is 25.78125 Gbd, single-rate, per IEEE 802.3by Clause 112. Transmit power is -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, link budget 5.3 dB per IEEE 802.3by Clause 112 Table 112-3 (RS-FEC per Clause 108 operates at the PCS layer and does not alter the optical power budget). Wavelength 850nm VCSEL, duplex LC/UPC, DOM per SFF-8472. Operating case temperature is 0 to 85 degrees Celsius (extended temperature range, EXT class per SFF MSA conventions), which differentiates WYMGJ from the standard 0 to 70 degrees Celsius Dell SFP28 SR ordering codes and suits deployments in racks with limited forced-air cooling and high-ambient indoor equipment rooms.

WYMGJ is a Dell ordering code for a 25GbE SFP28 SR short-reach module specified against Dell PowerSwitch data-center switches with 25G SFP28 interfaces. The primary in-scope platforms are the Dell PowerSwitch S5x00F-ON series (S5248F-ON with 48 x 25G SFP28 ports, S5212F-ON, S5232F-ON, S5224F-ON, S5296F-ON) and Dell PowerEdge servers with rNDC or OCP 25G SFP28 adapters. Dell is commonly referenced by resellers as cross-listing WYMGJ with the alternate ordering codes 407-BBZS and P7D7R for the same optical part; EdgeOptic's compatible targets the WYMGJ optical specification directly.

Dell's public position on optical compatibility for standard PowerSwitch platforms is that MSA-compliant 25G SFP28 modules operate on the host without a platform-side vendor-lock step. EdgeOptic's WYMGJ compatible carries the Dell EEPROM vendor and part-number strings that OS10 reads on optic insertion, so the module is identified as a native Dell optic on the standard OS10 inventory path. Operators running a locked optic profile on a specific PowerSwitch SKU can request the exact EEPROM vendor and PN strings from EdgeOptic for verification before deployment.

On FEC, 25G FEC mode is configured at the MAC layer on each link partner and the optical path is agnostic to the host FEC profile. RS-FEC per IEEE 802.3by Clause 108 is the default path for 25GBASE-SR on Dell PowerSwitch and is the mode WYMGJ is specified against; Clause 74 Fire Code FEC (BASE-R) and no-FEC operation are supported at the optical layer where both link partners are configured for that FEC profile. DOM registers for transmit power, receive power, supply voltage, laser bias current and module case temperature are accessible through standard SFF-8472 reads on the OS10 transceiver-diagnostics interface and on any EEPROM-aware link partner. Every unit is factory-tested to the 25GBASE-SR optical specification per IEEE 802.3by Clause 112 before dispatch.
