Description
The FiberMania 400G QSFP-DD DR4 optical transceiver is a high-density, hot-pluggable module specifically engineered for high-speed 400 Gigabit Ethernet connectivity within modern data centers. Utilizing advanced 1310nm Silicon Photonics or EML laser technology, this module delivers robust performance over single-mode fiber (SMF) for distances up to 500 meters. It effectively bridges the gap between high-bandwidth requirements and power efficiency, making it an ideal choice for leaf-to-spine leaf architecture and large-scale cloud networking deployments.
This transceiver operates using 8 lanes of 50G PAM4 modulated electrical signals, aggregating to a total bandwidth of 400Gbps. It is fully compliant with the QSFP-DD Multi-Source Agreement (MSA) and IEEE 802.3bs standards, ensuring seamless interoperability with a wide range of networking equipment. With its integrated Digital Diagnostic Monitoring (DDM) and adherence to CMIS 4.0, network administrators can monitor real-time performance metrics such as temperature, voltage, and optical power to ensure maximum uptime.

Q&A
Q: Can this 400G DR4 module be used for breakout connections? A: Yes, this module is specifically designed to support 4x100G breakout applications. Using an MPO-12 to 4xLC single-mode breakout cable, you can connect one 400G port to four 100G DR1 ports on legacy or lower-speed switches.
Q: What are the cooling requirements for a 12W QSFP-DD module? A: Our QSFP-DD DR4 is designed with a Type 2 housing, which includes integrated fins or optimized surfaces for improved heat dissipation. It operates reliably within a standard 0 to 70°C case temperature range provided there is adequate airflow within the switch chassis.
Q: Does FiberMania offer customization for specific vendor compatibility? A: Absolutely. As a leading OEM/ODM partner, FiberMania provides professional EEPROM coding services. We can write custom compatibility code for all major switch and router brands to ensure the modules are recognized and function perfectly without “unsupported transceiver” warnings.
Q: How do you ensure the quality of these high-speed modules during production? A: We follow a rigorous testing protocol that includes automated optical testing, bit error rate (BER) verification, and real-switch interoperability testing. As an OEM-focused manufacturer, we maintain high standards to ensure our products meet your private label brand’s reputation for reliability.
