What is the modulation method of the 800G Twin-Port NDR 2xSR4 optical module?

8-channels of 100G-PAM4 electrical modulation, Two ports of 4-channel 100G-PAM4 optical modulation.

What is the transmission distance of the 800G Twin-Port NDR 2xSR4 optical module?

With the OM3 patch cable, the transmission distance is 30m, with the OM4 patch cable, the transmission distance is up to 50m.

What are the heat dissipation methods of the NDR module?

One is with "Finned Top" and the other is "Flat Top"; Generally speaking, the "Flat Top" module is mainly used on the NIC side, because the thickness of the NIC is limited. The "Finned Top" module has a module top design with heat dissipation fins, which can increase heat dissipation capacity and improve module performance and reliability in high-temperature environments. It is usually used in Quantum-2 and Spectrum-4 air-cooled switches.

Different Heat Sink Designs Upgrade the Level of Performance

Mastering the differences between flat top and finned top, ensuring high performance and stable data transmission.

Finned Top modules feature a top design equipped with heat dissipation fins. The integrated top heatsink enhances cooling efficiency when handling massive data. 800G OSFP optical modules integrated in a heat sink are applicable for Quantum-2 InfiniBand switches and Spectrum-4 Ethernet switches.

Flat Top module's height is 9.5 mm without heat sinks, relying on the heatsinks on the NIC ports to assist the module in cooling, which fits into compact or constrained spaces without interference. 400G OSFP form factor optical modules are used in CX7 HCA.

Questions & Answers

Ask a Question

Can I use only one port for the 800G Twin-Port NDR 2xSR4 optical module?

Yes, if only one of the ports is used, the rate is 400G.

What kind of optical fiber do I need to use with the 800G Twin-Port NDR 2xSR4 optical module?

When the connection rate of both devices is 2x400G-2x400G, it is paired with two OM4 MPO-12/APC patch cords, and the corresponding NADDOD model is M4MPOA12FB . When the connection rate of both devices is 2x400G-4x200G, it is paired with two multimode OM4 MPO-2xMPO-4/APC patch cords, and the corresponding NADDOD model is M4MPOA2x4F.

Why is the polished type of multimode patch cable used in the NDR module MPO/APC (Angled Polished Connector)?

100G-PAM4 optoelectronic devices are very sensitive to reflections occurring within the fiber, about 10% of the light is reflected back to the transmitter as it passes through the optical connector, distorting the data signal, APC's optical connector deflects this reflected light.

I had inquired with several suppliers about the MMA4Z00-NS optical module, but their delivery times were too long and couldn't meet our testing project requirements. Finally, I placed an order with NADDOD, and now I have received the shipment.
