Product Highlights

Accelerating Al Networking Innovation with Broadcom DSP & Broadcom VCSEL

NADDOD’s OSFP-400G-SR4H transceiver features an original-equivalent Broadcom DSP and Broadcom VCSEL design, meeting the stringent demands of AI data centers for superior signal integrity, low power consumption, low BER, and high stability. Rigorously tested and verified compatible with NVIDIA QM9700/QM9790, the module is widely recognized by customers.

Low BER on Par with NVIDIA Originals

During LL FEC (272,257) testing, NDD transceivers achieve Pre-FEC BER of -8~-10, and near-zero post-correction, reducing operations and maintenance (O&M) complexity and costs.

Why NADDOD

  • Module Availability
    Worry-Free - Rigorous authentic testing!
  • Multi-version Device Compatibility
    Multi-Version - Easy adaptation for each module!
  • High-Performance
    Actual Test Data-Better results intuitively!

Our Approach

Test scene
Test scene
NADDOD stringently selects a series of items in a professional testing environment to ensure the perfect blend of product performance and reliability. Including hardware compatibility (plugging, unplugging, rebooting), software compatibility (connectivity, parameters) and performance testing (DDM, BER, stability).

Questions & Answers

Ask a Question
Q:
What are the benefits of the Broadcom DSP & Broadcom VCSEL solution in real deployments?
A:
Broadcom is a leading provider of optical DSPs, known for advanced signal equalization and FEC. NADDOD’s Broadcom DSP & Broadcom VCSEL solution ensures lower BER and higher link stability—ideal for AI training and inference workloads requiring consistent, high-performance connectivity. Compared to modules using alternative chip solutions, it offers higher reliability and lower maintenance risks.
Q:
Can 400G NDR SR4 be interconnected with 800G Twin-Port NDR 2xSR4?
A:
Yes, 800G Twin-Port NDR 2xSR4 with two OM4 MPO-12/APC patch cables can be connected to two 400G NDR SR4 optical modules.
Q:
Why is the polished type of multimode patch cable used with NDR module MPO/APC (Angled Polished Connector)?
A:
The 100G-PAM4 optoelectronic device is very sensitive to reflections occurring inside the fiber, about 10% of the light is reflected towards the transmitter when passing through the optical connector, distorting the data signal, and the APC's optical connector deflects this reflected light.
