Lenovo compatible 7G17A03537 Description
EdgeOptic's 7G17A03537 compatible is a Lenovo-coded dual-rate 10G/25G SR SFP28 transceiver, a direct replacement for the Lenovo Dual Rate 10G/25G SR SFP28 Transceiver (OEM part number 7G17A03537). It ships with Lenovo-recognized EEPROM, so ThinkSystem servers and ThinkSystem network switches identify the module as a native Lenovo optic.
The module operates at 25GBASE-SR per IEEE 802.3by Clause 112 and at 10GBASE-SR per IEEE 802.3ae on the same port. 850nm VCSEL transmitter, PIN photodiode receiver, LC/UPC duplex connector on a single pair of OM3, OM4 or OM5 multimode fiber. Reach is 100m on OM4 and OM5, 70m on OM3. Transmit power is -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, optical budget 5.3 dB. Line rate covers 8.5 to 25.78 Gbps so the same module serves 10GbE and 25GbE host ports without a part-number swap. Power draw is 0.3W maximum. DOM per SFF-8472, operating case temperature 0 to 70 degrees C.
The 7G17A03537 is the Lenovo ServerProven part number for the dual-rate 10G/25G SR SFP28. Dual-rate operation is the key practical feature: in a mixed 10GbE-and-25GbE server refresh, the same part number seats in both older 10G NIC ports and newer 25G NIC ports, which simplifies sparing and staging. On the server side the module pairs with the Lenovo ThinkSystem Broadcom 57454 10/25GbE SFP28 PCIe adapter and the Broadcom 57414 10/25GbE SFP28 PCIe adapter across ThinkSystem server families including SR630, SR650, SD630 V2, SR250 V2, ST250 V2 and ST650 V2. On the switching side it operates in the Lenovo ThinkSystem NE2552E Flex Switch 25G ports. Use ThinkSystem server-family-level compatibility references; specific ThinkSystem firmware minima vary by NIC firmware release.
Important restriction: the 7G17A03537 is qualified only in PCIe-form-factor Broadcom 57454 and 57414 adapters. It is NOT supported when the same NIC silicon is installed in an OCP 3.0 adapter slot. Lenovo documentation is explicit on this point; operators planning a ThinkSystem OCP-based 25G NIC refresh need a different Lenovo SFP28 OPN for the OCP path. If your deployment mixes PCIe and OCP adapter slots, confirm OPN coverage against the Lenovo ServerProven option page for each adapter line before consolidating on a single sparing optic.
DOM registers for transmit power, receive power, laser bias current, module temperature and supply voltage are exposed through the Broadcom NIC driver diagnostic commands on the server side, and through the ThinkSystem switch CLI and standard SFP28 SNMP MIBs on the NE2552E side. Every unit is factory-tested to the 25GBASE-SR optical specification per IEEE 802.3by Clause 112 and also validated at 10GBASE-SR rate. The module carries CE, RoHS, Class 1 FDA and IEC 60825-1 certifications.

Frequently Asked Questions
Can the Lenovo 7G17A03537 operate at both 10GbE and 25GbE speeds?
Yes. The 7G17A03537 is Lenovo's dual-rate 10G/25G SR SFP28 transceiver per the ServerProven option listing. Line rate covers 8.5 to 25.78 Gbps, which spans 10GBASE-SR per IEEE 802.3ae and 25GBASE-SR per IEEE 802.3by. The active port speed is selected by the host NIC or switch configuration rather than by the module itself, so the same module drops into a 10GbE port on an older ThinkSystem generation and a 25GbE port on a current one without any hardware change.
Is the 7G17A03537 supported in Lenovo ThinkSystem OCP adapter slots?
No. The 7G17A03537 is supported in PCIe-form-factor Broadcom 57454 and 57414 adapters, but it is not qualified for OCP 3.0 adapter slots even when the same Broadcom NIC silicon is installed in OCP form factor. Lenovo documentation is explicit about this restriction. If your ThinkSystem server uses an OCP-based 25G NIC, you need a different Lenovo SFP28 OPN for that path; confirm the correct option against the ServerProven page for the specific OCP adapter before ordering.
Which Lenovo ThinkSystem servers accept the 7G17A03537 SFP28 transceiver?
Confirmed compatible ThinkSystem servers include SR630, SR650, SD630 V2, SR250 V2, ST250 V2 and ST650 V2 when equipped with the Lenovo ThinkSystem Broadcom 57454 10/25GbE SFP28 PCIe adapter or the Broadcom 57414 10/25GbE SFP28 PCIe adapter. On the switching side, the Lenovo ThinkSystem NE2552E Flex Switch also accepts this module. Confirm your specific ThinkSystem firmware level and NIC firmware version against the Lenovo ServerProven option page if you are deploying at scale.
Does the 7G17A03537 work on OM3 fiber or is OM4 required for 100m reach?
Both OM3 and OM4 are supported, but the reach envelope depends on fiber grade. OM4 and OM5 reach is 100m. OM3 reach is 70m. If your cabling plant is OM3 and the run needs to exceed 70m, re-terminate with OM4 for the full 100m envelope or consider a 25GBASE-LR module on single-mode fiber for longer spans. At 10GbE line rate the module also works on OM3 and OM4; 10GBASE-SR reach on the same fiber grades is longer than 25GBASE-SR because the lower modulation rate is less limited by modal dispersion.
