Lenovo compatible 7G17A03537 Description
EdgeOptic's 7G17A03537 compatible is a Lenovo-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor 25GBASE-SR SFP28 transceiver, a direct replacement for the Lenovo Dual Rate 10G/25G SR SFP28 Transceiver. It ships with Lenovo-recognized EEPROM so ThinkSystem servers and the NE2552E Flex Switch identify the optic as a native Lenovo part, and the Broadcom 57454 and 57414 PCIe adapters the module is paired with read it through standard SFF-8472 access.
Optical behavior is 25GBASE-SR per IEEE 802.3by Clause 112 over duplex multimode fiber: 100 m on OM4 or OM5, 70 m on OM3. Line signaling rate is 25.78125 Gbd, with dual-rate operation down to 10.3125 Gbd for 10GBASE-SR on mixed-speed infrastructure. TX power −5 dBm minimum and +2.4 dBm maximum from an 850 nm VCSEL, RX sensitivity −10.3 dBm on the PIN photodiode receiver, 5.3 dB link budget with host RS-FEC per IEEE 802.3by Clause 108 RS(528,514). Duplex LC/UPC connector, DOM per SFF-8472, 0.3 W maximum power, 0 to 70 °C commercial operating range.
7G17A03537 is the Lenovo option part number for the ThinkSystem dual-rate 10G/25G SR SFP28 transceiver. Per the Lenovo Press product guide for the ThinkSystem Broadcom 57454 10/25GbE SFP28 adapter (LP1198), the part is supported with the Broadcom 57454 and 57414 PCIe-form-factor adapters and is explicitly excluded from OCP-form-factor adapter slots. The ServerProven option page lists the ThinkSystem NE2552E Flex Switch (4SG7A08868) as a companion product on the switch side. The OCP restriction is the single most important deployment edge case to confirm before ordering against an OCP riser chassis.
Platform scope is Lenovo ThinkSystem rack and tower server families carrying the Broadcom 57454 or 57414 25 GbE PCIe adapter, paired with the ThinkSystem NE2552E Flex Switch on the switch side. Verify the specific ThinkSystem chassis and firmware level against the Lenovo Data Center Compatibility tool and the LP1198 server compatibility tables for the generation you are deploying.
DOM registers for transmit power, receive power, supply voltage, laser bias and module case temperature are exposed through SFF-8472. On the server side they are accessible via the standard Linux ethtool interface on hosts with Broadcom 57454 or 57414 adapters; on the NE2552E switch side they surface through the standard SFP28 SNMP MIBs per Lenovo Networking management documentation. The optic meets the 25GBASE-SR optical specification per IEEE 802.3by Clause 112, with host RS-FEC at the MAC layer per IEEE 802.3by Clause 108 where the link partner requires it.
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 about 7G17A03537
Is the 7G17A03537 supported in Lenovo ThinkSystem OCP adapter slots?
No. Per the Lenovo Press product guide for the ThinkSystem Broadcom 57454 10/25GbE SFP28 adapter family (LP1198), 7G17A03537 is supported only in the PCIe form-factor Broadcom 57454 and 57414 adapters and is explicitly excluded from OCP form-factor adapter slots. The Dec 1, 2020 change history on that guide records the part as 'restored... however not supported installed in the OCP adapter.' For ThinkSystem chassis where the 25 GbE pathway runs through an OCP riser, use the OCP-supported transceiver listed in the LP1198 OCP table instead.
Can the Lenovo 7G17A03537 operate at both 10GbE and 25GbE speeds?
Yes. Lenovo ServerProven names the product 'Dual Rate 10G/25G SR SFP28 Transceiver.' The EdgeOptic 7G17A03537 compatible follows the 25G-SFP28-100 root specification: 25GBASE-SR at 25.78125 Gbd per IEEE 802.3by Clause 112 and 10GBASE-SR at 10.3125 Gbd per IEEE 802.3. Negotiated rate is set by the host NIC and switch-side port configuration; the same part number can sit in a 10 GbE port in one chassis and a 25 GbE port in another without re-ordering.
Which Lenovo ThinkSystem servers accept the 7G17A03537 SFP28 transceiver?
7G17A03537 is the transceiver listed against the ThinkSystem Broadcom 57454 10/25GbE SFP28 PCIe adapter family in Lenovo Press LP1198, which covers a broad ThinkSystem rack and tower server population including V1 through V4 generation chassis. Specific per-chassis qualification varies by adapter form factor and firmware level, so verify the exact ThinkSystem server model against the Lenovo Data Center Compatibility tool and the LP1198 server compatibility tables before deployment at scale. Companion product 4SG7A08868 (ThinkSystem NE2552E Flex Switch) is listed on the 7G17A03537 ServerProven page.
