Huawei QSFP28‑100G‑LR4 – Full DescriptionHuawei QSFP28‑100G‑LR4 Optical Transceivers are 100 Gigabit Ethernet optical modules designed for high‑speed long‑distance network connectivity over single‑mode fiber (SMF). These transceivers use the QSFP28 form factor, which is a compact, hot‑pluggable interface standard that supports data rates up to 100 Gbps and is widely used in data centers, enterprise backbones, service provider networks, and high‑performance computing environments. They adhere to 100GBASE‑LR4 standards, transmitting four independent 25 Gbps signals over a single optical fiber pair using LAN‑WDM technology.
These modules are engineered for long‑reach optical links up to 10 km on single‑mode fiber with LC duplex connectors and include digital diagnostic monitoring (DDM) to report real‑time operating parameters like temperature, voltage, and optical power.

How Optical Transceivers Work (Quick Guide)
1. Insert into QSFP28 Port:
- Plug the QSFP28‑100G‑LR4 transceiver into a 100 G QSFP28 optical port on a switch, router, or optical platform.
2. Connect Fiber Cable:
- Use single‑mode fiber (OS2) with LC duplex connectors to connect the transmitter on one device to the receiver on the other.
3. Automatic Link Negotiation:
- Once properly seated and fiber connected, the optical link will establish and negotiate at 100 Gbps.
4. Verify with Diagnostics:
- Use built‑in DDM/DOM to monitor parameters like optical power, temperature, and voltage for health & troubleshooting.
Compatibility
Device Compatibility
Huawei QSFP28‑100G‑LR4 modules are compatible with many Huawei routers, switches and optical platforms that have 100 G QSFP28 ports (e.g., CloudEngine, S‑Series, NE‑Series, etc.).
General Compatibility Notes:
- Works with Huawei network equipment that supports 100GBASE‑LR4 optics.
- Compatible with other vendors’ devices that support standard QSFP28 100GBASE‑LR4 optics (Cisco, Juniper, Arista, etc.), provided multi‑vendor optics are supported.
- Ensure the port supports 100 Gbps and LR4 optical standard before deployment.
⚠️ Some devices may reject non‑OEM optics unless explicitly permitted in software/licensing.
Frequently Asked Questions (FAQ)
1. What does LR4 mean?
LR4 stands for Long Reach and refers to optical modules that support 100 Gbps transmission up to 10 km over single‑mode fiber using wavelength division multiplexing.
2. What fiber type is needed?
