The QSFP28 LR4 module transmits 100Gbps using four independent 25Gbps optical channels, each operating at a different wavelength. These signals are multiplexed into a single fiber using WDM technology.
This design allows:
- Long-distance transmission (up to 10km)
- High stability over single-mode fiber
- Efficient bandwidth utilization
This module is widely compatible with:
- Huawei CloudEngine series switches
- Enterprise core switches
- Data center optical networks
- Telecom transmission systems
- Data center interconnect (DCI)
- Enterprise backbone networks
- Metro Ethernet
- Cloud infrastructure
- High-speed ISP transmission links
- LR4: Single-mode fiber, up to 10km
- SR4: Multimode fiber, up to 100m
- LR4 is ideal for long-distance backbone links
- LR4: Higher performance, 10km reach
- CWDM4: Lower cost, up to 2km
- LR4 is preferred for carrier-grade deployments
Yes, this module is designed to be compatible with Huawei QSFP28 ports supporting 100GBASE-LR4 standard.
It requires single-mode fiber (SMF G.652) with LC duplex connectors.
