Lenovo 7G17A03540 Compatible 100G QSFP28 LR4 Transceiver

EdgeOptic's 7G17A03540 compatible is a Lenovo-coded 100GBASE-LR4 QSFP28 transceiver built on the EdgeOptic 100G-QSFP28-10 platform. The 7G17A03540 ordering code ships with Lenovo ThinkSystem RackSwitch chassis as the standard 100G long-reach optic. The compatible carries Lenovo-recognized EEPROM identifiers so ThinkSystem switches surface the expected ordering code in CLI output and management telemetry, and the module slots into any QSFP28 cage on the host with the same insertion, hot-swap, and DDM behavior as the original Lenovo module.

The optical interface follows IEEE 802.3ba Clause 88 100GBASE-LR4. Four 25.78 Gbps NRZ lanes ride the LAN WDM grid at 1295.56, 1300.05, 1304.58, and 1309.14 nm, then multiplex onto a single LC duplex pair of single-mode fiber. The 6.3 dB optical path loss budget supports a full 10 km reach on G.652 SMF, and the module also operates over shorter ThinkSystem in-rack and inter-rack uplinks where the optical budget is not fully exercised. The operating temperature window is 0 to 70 C commercial. The module supports forward error correction at the host MAC layer for clean operation on links that exercise the full optical budget, and reports DDM telemetry per SFF-8636 for tx power, rx power, bias current, supply voltage, and case temperature on the standard QSFP28 management interface. Class 1 laser safety, RoHS compliance, and CE marking apply.

Lenovo lists 7G17A03540 against the ThinkSystem NE10032 RackSwitch (feature code AV1E) and the ThinkSystem NE2580O RackSwitch per Lenovo Press lp0609 and Lenovo ServerProven. For platforms outside that list, including newer ThinkSystem switches that may have been added since the lp0609 product guide, check the Lenovo Data Center Support compatibility tool against the specific switch model and firmware before ordering.

Typical deployment scenarios include ISP aggregation and backbone uplinks, mobile operator core and backhaul links, and data center site interconnects on QSFP28 hosts that accept third-party 100GBASE-LR4 optics per the QSFP28 MSA. Ships next business day from EU stock with a lifetime warranty. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms.
