Huawei compatible QSFP-100G-ER4-Lite Description
QSFP-100G-ER4-Lite is Huawei's part number for a 100GBASE-ER4 Lite QSFP28 transceiver, also referenced under material code 02311YXR in Huawei procurement systems. EdgeOptic's compatible replacement is built on our 100G-QSFP28-40 platform, matching the original optical and electrical specifications. The module reaches 40 km over standard G.652 single-mode fiber with duplex LC/UPC connectors.
The module transmits 100G as four 25G NRZ lanes on LAN WDM wavelengths (1295.56, 1300.05, 1304.58, 1309.14 nm), multiplexed into a single fiber pair. The ER4 Lite specification targets 40 km reach with FEC assistance from the host MAC layer. This differs from the full 100GBASE-ER4 standard, which specifies 40 km without FEC. ER4 Lite modules operate within a relaxed optical budget that relies on the host-side FEC engine to close the link over extended metropolitan and campus spans. The relaxed budget reduces manufacturing cost compared to full ER4 while maintaining the same practical reach in networks where FEC is always enabled.
The transmit side uses four EML (electro-absorption modulated laser) transmitters, each generating a 25G NRZ signal on its assigned LAN WDM wavelength. The receive side employs four PIN photodiodes with TIA (transimpedance amplifier) stages. Per-lane launch power is approximately -2.9 dBm minimum, and receiver sensitivity reaches around -20.9 dBm with FEC. These parameters support deployment over standard G.652 fiber up to 40 km without optical amplification or dispersion compensation.
Huawei qualifies this transceiver for CloudEngine CE8800 (CE8861-4C-EI), CE12800 (CE12804/08/16), and CE16800 data center and core switches. The CE series switch firmware validates transceiver vendor IDs during module insertion. EdgeOptic's compatible is programmed with Huawei-recognized EEPROM identifiers, so the CloudEngine platform reports it as a qualified module in 'display transceiver' output. DDM telemetry (Tx/Rx optical power per lane, temperature, bias current, supply voltage) is fully supported and visible through Huawei's iMaster NCE and eSight management platforms.
When ordering through Huawei channels, the material number 02311YXR maps to the QSFP-100G-ER4-Lite. Both designations refer to the same transceiver specification. Huawei's material numbering system uses the 023xxxxx format for optical transceiver modules, while the QSFP-100G-ER4-Lite is the descriptive product name used in configuration guides and compatibility matrices. EdgeOptic's compatible carries the same EEPROM data structure for both identifiers. For CloudEngine deployment projects or volume pricing, contact our sales team
Frequently Asked Questions
What is the Huawei BOM code for QSFP-100G-ER4-Lite?
The Huawei numeric BOM code is 02311YXR. Both QSFP-100G-ER4-Lite and 02311YXR refer to the same module. If your purchase order or BOM uses either designation, this is the correct replacement.
Which Huawei platforms support the QSFP-100G-ER4-Lite?
Supported platforms include Huawei CloudEngine CE6800, CE8800, CE9800, CE12800, and CE16800 series switches, and NetEngine 8000 M8/M14 and NE40E series routers. Check the Huawei hardware compatibility matrix for your specific model and firmware version.
What is the difference between QSFP-100G-ER4-Lite and QSFP-100G-ER4 on Huawei?
The ER4-Lite (02311YXR) uses APD receivers at lower power and reaches 40 km with host FEC enabled, or 30 km without FEC. The full ER4 (02313HLU) reaches 40 km without requiring FEC but at higher cost and power. For most deployments where FEC is already enabled, the ER4-Lite is the more cost-effective choice.
Does the QSFP-100G-ER4-Lite require FEC for 40 km?
Yes. Without host FEC, the module reaches approximately 30 km. With FEC enabled, reach extends to 40 km. Configure FEC on the Huawei switch or router interface and ensure the remote end matches.
