Huawei QSFP28‑100G‑LR4 Optical Module – Full Product Description
The Huawei QSFP28‑100G‑LR4 optical module with part number 02311KNU is a high‑performance, hot‑pluggable 100 Gigabit Ethernet transceiver designed for long‑reach optical connections in modern network infrastructures. It adheres to the 100GBASE‑LR4 standard, enabling 100 Gbps data transmission over single‑mode fiber (SMF) up to 10 km. The QSFP28 form factor supports four independent 25 Gbps lanes combined with LC duplex fiber connectors and is widely used in data center interconnects, core network links, enterprise backbones, and telecom infrastructure.
This module also supports Digital Diagnostic Monitoring (DDM) for real‑time health and performance monitoring of the optics (e.g., temperature, optical output, received power).

How It Works – Quick Guide
1. Plug In the Transceiver:
- Insert the QSFP28‑100G‑LR4 into a 100G QSFP28 slot on a switch/router that supports 100GBASE‑LR4 optics.
2. Fiber Connection:
- Use single‑mode fiber (SMF) with LC duplex connectors to connect the module to the remote end device.
3. Link Establishment:
- Once properly seated and the fiber connected, the devices negotiate and establish a 100 Gbps link.
4. Monitor Status:
- Use network management software or CLI to read DDM data (temperature, power levels) for diagnostics.
Frequently Asked Questions (FAQ)
1. What does “LR4” mean?
LR4 stands for Long‑Reach, 4‑lane optical transmission, meaning each 100 Gbps signal is split across four 25 Gbps wavelengths, enabling long‑distance transmission over single‑mode fiber.
2. What is the maximum reach of this optical module?
It supports up to 10 km over single‑mode fiber (G.652) using LC duplex connectors.
3. Can this module be hot‑swapped?
Yes. The QSFP28‑100G‑LR4 is hot‑pluggable, so it can be inserted or removed without powering down the system.
4. Does it support real‑time diagnostics?
Yes — it features Digital Diagnostic Monitoring (DDM) for live status of optic performance (temperature, power, voltage, etc.).
5. What type of fiber and connector is needed?
Use single‑mode optical fiber (G.652) with LC duplex connectors.
6. Is it compatible with non‑Huawei equipment?
It can be compatible with other vendors’ devices that support the 100GBASE‑LR4 QSFP28 standard and allow third‑party optics. However, some switches/routers may lock optics by vendor ID or firmware and require configuration to permit third‑party modules.
