Product Description
400G QSFP112 SR4 Optical Transceiver — High-Speed, Low Power, DDM Support
This optical transceiver module delivers 400G connectivity over OM4 multimode fiber with a reach of up to 100 meters. Designed for data center and high-performance computing environments, it features four independent 106.25 Gbps lanes, digital diagnostics monitoring, and compliance with industry standards including IEEE 802.3db, CMIS 4.0, and RoHS.
Key Features
- 4x106.25Gbps PAM4 modulation over 850nm VCSEL
- Reach up to 100m on OM4 MMF
- Hot-pluggable QSFP112 form factor
- Digital Diagnostics Monitoring (DDM)
- Low power consumption: ≤10W
- Single MPO-12 connector
Technology & Standards
This optical module complies with IEEE 802.3db and 802.3ck, CMIS 4.0, and QSFP112 MSA. It uses PAM4 modulation and integrates advanced DDM functionality for real-time performance tracking.
How It Works
The transceiver converts electrical signals into optical signals using four 850nm VCSEL lasers. Each lane operates at 53.125 GBaud, supporting an aggregate data rate of 425 Gbps. The receiver uses PIN photodiodes to convert optical signals back to electrical format.
Applications
- Data center spine-leaf architecture
- High-performance computing clusters
- Cloud infrastructure interconnects
- Enterprise network aggregation
