The Huawei QSFP-40G-LR4 is an MSA-compliant QSFP+ 40GBase-LR4 optical transceiver module designed for single-mode fiber transmission at 1310 nm over distances up to 10 km using LC duplex connectors.
The Huawei QSFP-40G-LR4 operates at a central wavelength of 1310 nm, using four multiplexed channels for 40 Gbps aggregate throughput.
This module supports single-mode fiber links up to 10 km under standard conditions, making it ideal for campus, metro, and data-center interconnects.
The QSFP-40G-LR4 uses a duplex LC connector interface, ensuring compatibility with standard single-mode fiber cabling systems.
The transceiver delivers an aggregate data rate of 40 Gbps, split across four independent 10 Gbps channels.
Yes, the QSFP-40G-LR4 is hot-swappable; you can insert or remove the module without powering down the host device.
The typical power consumption for the Huawei QSFP-40G-LR4 is 3.5 W, meeting the QSFP+ thermal and power budget specifications.
This MSA-compliant QSFP+ module is compatible with Huawei switches, routers, and most third-party devices supporting 40GBase-LR4 QSFP+ interfaces.
The standard operating temperature range is 0 °C to 70 °C (32 °F to 158 °F), suitable for typical data-center environments.
Align the module with the QSFP+ port, slide it in until the latch clicks, and then connect the LC duplex cable to the transceiver’s ports.
The module uses the QSFP+ form factor, which measures 18.35 mm × 68.5 mm × 8.5 mm and fits standard QSFP+ slots.
Yes, as long as the equipment supports MSA-compliant QSFP+ 40GBase-LR4 modules, the Huawei QSFP-40G-LR4 will interoperate seamlessly.
LR4 transceivers use single-mode fiber for up to 10 km links at 1310 nm, whereas SR4 modules use multimode fiber for short-reach (<100 m) links at 850 nm.
The QSFP-40G-LR4 uses coarse WDM to multiplex four 10 Gbps channels at 1310 nm; no external CWDM multiplexer is required.
Verify fiber polarity, check LC connectors for dust, confirm host port configuration, and ensure the link distance does not exceed 10 km.
Huawei typically offers a one-year limited warranty on the QSFP-40G-LR4, covering manufacturing defects under normal operating conditions.
