400G QSFP112 SR4 Optical Transceiver Module
Experience high-performance data center connectivity with our 400G QSFP112 SR4 optical transceiver module. Designed for short-reach multimode fiber applications, this module supports data rates up to 425Gbps over 100m using OM4 fiber. Featuring low power consumption, hot-pluggability, and robust diagnostic monitoring, it is an ideal solution for modern data centers and high-speed networks.
Key Features
- Hot-pluggable QSFP112 form factor with digital diagnostics monitoring (DDM)
- 4 independent lanes at 106.25Gbps per lane, totaling 425Gbps
- Reach up to 100m on OM4 multimode fiber
- 850nm VCSEL laser and PIN receiver technology
- Low power consumption, max 10W
- Compliant with IEEE 802.3db, 802.3ck, and CMIS 4.0
- RoHS 6/6 compliant and Class 1 Laser product
Technology & Standards
This optical module complies with industry standards including IEEE 802.3db, IEEE 802.3ck, and the QSFP112 MSA. It uses PAM4 modulation and supports 400GAUI-4 electrical interface. The module integrates advanced digital diagnostics for real-time monitoring of temperature, voltage, TX/RX power, and bias current.
Working Principle
The transceiver converts electrical signals into optical signals using four 850nm VCSEL lasers. Each lane operates independently, transmitting data over OM4 fiber via an MPO-12 connector. On the receiver side, a PIN photodiode array converts the optical signals back to electrical data, ensuring high-speed, low-latency communication.
Applications
- Data center interconnects and spine-leaf architectures
- High-performance computing (HPC) clusters
- Cloud infrastructure and enterprise networking
- Telecommunication and ISP core networks
