NVIDIA/Mellanox Compatible SiPh 1.6T FR8 (2x FR4) Twin-port OSFP224 RHS/Flat Top PAM4 1310nm 2km Dual Duplex LC/UPC SMF DDM InfiniBand XDR Optical Transceiver Module for Liquid-Cooled Switches

Got this 1.6T module for our core upgrade. Plugged it in, no issues, and the price was right. Definitely ordering more.

Plugged it into the switch, fired it up, and it's been pushing traffic non-stop without a single hiccup.

We were impressed by the build quality. Everything looked well-made, and the module fit perfectly in our liquid-cooled switch without any issues.

We were looking for a higher-capacity option without increasing the number of switch ports, and this 1.6T module fit the requirement well. The twin-port architecture helped simplify our cabling layout, and overall deployment was cleaner than expected. A practical solution for high-bandwidth environments.

The high bandwidth capability was the main reason we selected it, and the dual-port design helped improve rack-level connectivity. The RHS form factor also worked well in our thermal management setup.

We purchased several of these 1.6T modules for a liquid-cooled AI cluster upgrade. All units were recognized immediately by our switches, and the links came up without any tuning. Signal quality remained stable during stress testing, and temperatures stayed within expectations.

When we purchased this 1.6T module, our current business wasn't fully utilizing such high bandwidth; it was more about preparing for the next phase of expansion. The biggest takeaway from the testing process is that it makes future upgrades much less stressful. Compared to changing the architecture every few years, we now prefer to plan ahead. At least based on the current test results, this choice has not been regrettable.

When we make equipment selections internally, we test products from several suppliers simultaneously. The reason this 1.6T module was ultimately chosen is quite simple—the test results were relatively stable. Its performance was roughly the same across different time periods and equipment combinations, demonstrating strong consistency.

It’s easy to use, fast, and has been a great experience so far. Overall, it’s been a very good choice for my online shopping needs.

Ærlig talt, for den ytelsen du får, er det et røverkjøp. Dette er mitt tredje kjøp fra QSFPTEK, og jeg planlegger allerede neste bestilling til neste utvidelsesfase. Fortsett med det gode arbeidet.
