Product Description
400G DR4 QSFP-DD Optical Transceiver Module — 500m Reach, Low Power, CMIS 4.0
1.QSFP-DD 400G DR4 Product Overview
The CC-QSFD04DR4-12D is a high-performance optical transceiver module designed for 400G Ethernet applications. It supports both 400G DR4 aggregation and 4x100G breakout modes over single-mode fiber up to 500 meters. Compliant with QSFP-DD MSA and IEEE standards, this optical module offers low power consumption, advanced management interface, and reliable performance for data center and enterprise networks.
2. QSFP-DD 400G DR4 Key Features
- Supports 400GBASE-DR4 and 100GBASE-DR breakout mode
- MPO-12 connector with 8° angled end-face
- Power consumption < 8W (target)
- Operating case temperature: 0°C to 70°C
- CMIS 4.0 management interface
- Hot-pluggable QSFP-DD form factor
3. QSFP-DD 400G DR4 Technology & Standards
The module complies with IEEE 802.3-2022, QSFP-DD MSA, and CMIS 4.0. It uses PAM4 modulation and integrates cooled EA-DFB lasers and PIN photodiodes for superior signal integrity. This optical transceiver module supports both 400GAUI-8 and 100GAUI-2 electrical interfaces.
4. Working Principle
The transceiver converts eight 26.5625 GBd PAM4 electrical lanes into four 53.125 GBd optical channels using an internal DSP gearbox. In breakout mode, it supports four independent 100G channels. The optical module ensures low BER with integrated FEC support.
5. QSFP-DD 400G DR4 Applications
- Data center interconnects
- Switch and router interconnections
- High-performance computing networks
- Cloud infrastructure
