QSFP28-100G-LR4 (02311KNU) Huawei compatible QSFP28 module - Price & Datasheet

QSFP28-100G-LR4 is a Huawei part number for a 100GBASE-LR4 QSFP28 optical transceiver, also referenced by Huawei’s material code 02311KNU. Our compatible version uses the same base module as our 100G-QSFP28-10 product, built to MSA specifications with Huawei-specific EEPROM programming.

The module transmits 100GbE over single-mode fiber using LAN WDM technology. Four wavelength channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm each carry 25.78125 Gbps with NRZ modulation, for an aggregate line rate of 103.125 Gbps. The transmitter uses an EML (Electro-absorption Modulated Laser) array and the receiver a PIN photodiode array. The four channels are multiplexed within the 1310 nm window and carried over a single duplex LC fiber pair.

The module provides a minimum optical link budget of 6.3 dB per IEEE 802.3ba, which supports distances up to 10 km over OS2 (G.652.D) single-mode fiber. Actual distance depends on your fiber attenuation and connector losses. The dual LC/UPC connector interface works with standard SMF patch cords and structured cabling.

Digital diagnostic monitoring (DDM/DOM) provides real-time readings of transmitted and received optical power, module temperature, laser bias current, and supply voltage through the SFF-8636 management interface. The module has no internal FEC engine, but is fully transparent to host-side RS-FEC (IEEE 802.3bj Clause 91) running in the switch ASIC. The module conforms to the QSFP28 MSA (SFF-8665) and presents a CAUI-4 host electrical interface (4x25G NRZ lanes per IEEE 802.3bj Clause 83). Operating temperature is 0 to 70°C with maximum power consumption of 3.5W.

Our module is programmed with Huawei-specific EEPROM data and has been compatibility-tested on Huawei VRP platforms including CloudEngine CE6800, CE8800, CE12800, and CE16800 series data center switches, as well as NetEngine 8000 and NE40E routers. It works in any Huawei equipment that lists QSFP28-100G-LR4 in its supported transceiver table. Use display interface 100GE x/x/x transceiver in VRP to verify DDM readings after insertion. We can also supply the module coded for other vendors; contact our sales team if you need alternative platform coding.

The transceiver meets IEEE 802.3ba and IEEE 802.3bm 100GBASE-LR4 requirements and conforms to the QSFP28 MSA (SFF-8665, IEEE 802.3ba 100GBASE-LR4). It is CE/RoHS certified and compliant with Class 1 FDA and IEC 60825-1 laser safety standards. We measure optical parameters and inspect connectors on every unit before shipment. EEPROM data is validated against the Huawei platform configuration. If you need technical consultation or a volume price for your project, contact our sales team.
