I am using a 1.6T module on the Quantum-X800 Q3400 device, connected to an 800G 2xDR4 on the QM9700 switch with 1:2 MPO-12/APC SMF single-mode patch cable, to achieve 1.6T-2x800G rate interconnection. Is this possible?

No, the 800G 2xDR4 optical module uses 100G-PAM4/lane, while the 1.6T 2xDR4 OSFP224 optical module use 200G-PAM4/lane. The channel signal rates are mismatched,they cannot be interconnected.

What are the main applications of high-speed 1.6T OSFP224 optical modules?

They are used to expand AI clusters in data centers, promoting the industry's transition to a network architecture of 51.2Tbps per RU.

What upgrades and changes have been made from 800G 2xDR4 optical modules to 1.6T 2xDR4 OSFP224 optical modules?

The adoption of the industry-leading 3nm DSP chips support PAM-4 signal processing at up to 200Gbps, not only enhancing the data transfer speed and bandwidth density but also optimizing power consumption and thermal performance.

Questions & Answers

Ask a Question

Q:

What’s the difference between EML and SiPh in optical modules?

A:

EML offers high stability and mature manufacturing, making it ideal for long-reach transmissions. SiPh, by contrast, is known for its low power consumption and ultra-low latency, making it a strong fit for high-density AI cluster deployments. These two approaches differ significantly in chip architecture, modulation methods, and application priorities.For a deeper look into how they compare and where each excels, check out our technical blog on ( EML vs. SiPh).

Q:

What’s the difference between 3nm and 5nm DSP in optical modules?

A:

3nm DSP offers lower power consumption and represents the latest technology. However, 5nm is more widely adopted, providing mature performance and shorter lead times.

Q:

Is the IB 1.6T 2xDR4 OSFP224 silicon photonics optical module compatible with the NVIDIA QM9700 switch?

A:

No, because there is a mismatch in the serdes rates. The QM9700 has an 8x100G serdes, where as the 1.6T 2xDR4 module has an 8x212G serdes, making it incompatible for use.
