FAQ

Ask a Question

Find answers to common questions about our products.

Can this module be used on NVIDIA DGX platforms?

No. This module adopts a Finned Top structure and is mainly used for air-cooled switch ports, while NVIDIA DGX platforms usually require Flat Top OSFP modules.

Is this module compatible with NVIDIA QM9790 switches?

Yes. This series of products is compatible with NVIDIA Quantum-2 platform devices, such as QM9700 / QM9790 switches. Before shipment, AICPLIGHT will test the products in our compatibility lab and can provide corresponding test reports or compatibility verification documents according to project requirements.

Why does OSFP-800G-2FR4 use a duplex LC interface instead of an MPO interface?

OSFP-800G-2FR4 adopts CWDM MUX/DEMUX technology, which can multiplex optical signals of multiple different wavelengths into one pair of fibers for transmission. Therefore, it does not need to use a parallel MPO interface and instead adopts a duplex LC interface.

What application scenarios is OSFP-800G-2FR4 suitable for?

OSFP-800G-2FR4 is suitable for long-distance high-speed interconnects in AI data centers, such as Spine-Spine, Spine-Core, and core switch interconnect scenarios. Compared with MPO parallel solutions, the duplex LC solution can reduce the number of fiber cores required.

Questions & Answers

Ask a question
s***a Confirmed Purchase
3.5

We chose 2FR4 because the site required a longer reach than SR and DR, and the duplex LC connection also fit our existing cabling better. After installation, the module was recognized normally, and the link status remained stable.

l***a Confirmed Purchase
5.0

This module uses fewer fiber cores than an MPO solution, which makes it more convenient for upgrading our existing data center cabling. We did not encounter any obvious compatibility issues during testing.

d***i Confirmed Purchase
3.1

We used it for high-speed switch-to-switch connections, and it has been running continuously for a period of time. Both the temperature and link status have remained within the normal range.

k***i Confirmed Purchase
2.6

We were initially concerned that an 800G 2km module might have high power consumption, but the actual test results were acceptable. We will evaluate further purchases based on the quantity required for the formal project.

n***u Confirmed Purchase
5.0

The products arrived faster than expected, and the accompanying information was complete. This made our incoming inspection and test record process easier, which is helpful for project delivery.
