Huawei QSFP‑100G‑LR4‑Lite Optical Transceiver Module - Full Description
The Huawei QSFP‑100G‑LR4‑Lite Transceiver is a 100 Gigabit Ethernet optical module in the QSFP28 form factor designed for short‑to‑mid‑reach single‑mode fiber (SMF) connectivity. It supports the 100GBASE‑LR4 optical standard and is ideal for enterprise networks, data centers, and metro edge links where high‑speed fiber links are needed over distances up to 2 km using LC duplex connectors.
Compared to standard LR4 modules optimized for up to 10 km, the “LR4‑Lite” variant trades off reach for cost‑effectiveness, making it suitable when full 10 km isn’t required but 100G performance and reliability are.
Key Features
- Form factor: QSFP28 hot‑pluggable optical transceiver
- Standard supported: 100GBASE‑LR4‑Lite (based on LR4 architecture)
- Data rate: Supports 100 Gbps Ethernet links
- Connector: LC duplex interface for single‑mode fiber (SMF)
- Wavelengths: Uses LAN‑WDM wavelengths (~1295 nm, 1300 nm, 1304 nm, 1309 nm)
- Reach: Up to 2 km on single‑mode fiber (G.652) — shorter than typical LR4 optics
- Transmit power: ~‑4.3 dBm to +4.5 dBm
- Receive sensitivity: ~‑8.6 dBm
- Connector ferrule: PC or UPC end face
- Operating temperature: 0 °C to 70 °C (commercial)
- Digital Diagnostic Monitoring (DDM): Supported (real‑time monitoring of optical power, temperature, voltage)
How It Works
1. Plug into QSFP28 Port:
- Insert the LR4‑Lite module into a 100G QSFP28 port on a switch, router, or optical platform that supports 100G optics.
2. Connect the Optical Fiber:
- Use single‑mode fiber (OS2) with LC duplex connectors on both ends (remote devices must also support LR4‑Lite/LR4 optics).
3. Establish the Link:
- Once the optic is seated and the fiber is connected, devices will establish a 100 Gbps optical link automatically.
4. Monitor with DDM:
- Use network management tools to view digital diagnostic data like transmit/receive power, temperature, and voltage for easier troubleshooting and health checks.
Frequently Asked Questions (FAQ)
1. What does “LR4‑Lite” mean?
“LR4‑Lite” refers to a cost‑optimized variant of the 100GBASE‑LR4 optical module designed for shorter reach (~2 km) vs. standard LR4’s 10 km capability. It still uses LAN‑WDM multi‑wavelength transmission over single‑mode fiber.
2. Can this module reach 10 km?
No — the LR4‑Lite module is specified up to ~2 km. For longer links up to 10 km, a standard 100GBASE‑LR4 module should be used instead.
3. What fiber type do I need?
You need single‑mode fiber (G.652/OS2) with LC duplex connectors — not multi‑mode fiber.
4. Is the module hot‑pluggable?
Yes — like most QSFP28 optics, it can be installed or removed without powering down the switch or router.
5. Does it support diagnostics?
Yes — it includes Digital Diagnostic Monitoring (DDM) for real‑time performance metrics (temperature, power, voltage, etc.).
6. Will it work with all 100G switches?
It may work with other brands that support standard 100GBASE‑LR4 QSFP28 optics, but many devices check module vendor IDs and firmware blocks may apply — always confirm compatibility on your specific device model.
