Cisco QSFP28-100G-BX10-U Compatible 100GBASE-BX10 BiDi QSFP28 1271nm-TX/1331nm-RX 10km DDM LC SMF Transceiver

The 100G QSFP28 BIDI 10km module perfectly suits our mid-range links. It seamlessly integrates with existing switches, delivering stable 100G throughput. Installation is straightforward, and the module feels solidly built. The only note: it runs slightly warm under heavy load, but this is completely unworrisome. Highly recommended.

The package arrived ahead of schedule, no damage or mishandling signs. Modules are well-secured in anti-static packaging with protective padding. Deployed it in our Nexus 9000, plug-and-play and was recognized immediately without any configuration hiccups.

Wanner a 100G link between two buildings about 8km apart over a single strand of fiber available between them. We used this compatible module in a Cisco Nexus 92300YC switch on one end and its "D" counterpart (the one with reversed wavelengths) in a switch at the other building. It's been running for months without a single error or interruption.

The plug-and-play installation process was simple, and the device connected seamlessly with our switches without any compatibility issues. Performance has been stable with low latency and no noticeable packet drops. The build also feels solid.

This 100G optical module is overall in line with the description on the website, and the transmission performance is stable enough to meet our testing standards. There is no obstacle to plug and play on our equipment, and the product quality is achieved. But there are still got thing to improve, the packaging of the product is relatively simple, I think QSFPTEK should be better in packaging, as a precision instrument, it should be better in packaging.

Very satisfied with this optical module, high stability, while the installation is very convenient, for high-speed connection needs can be perfectly satisfied, if you need a reliable optical module, this is definitely worth recommending!

I bought a pair of 10km and 20km modules. They are compatible with the switch just like the 10G modules I bought before, and there is no loss in throughput.

I have been using this module for two months now and have come to write this review. During these two months, this module has given us a very stable connection experience with minimal latency during transmission. It performs very well in long distance and high bandwidth applications. Highly recommended!

Purchased 5 pairs of QSFP28 bidi modules, paired them up and experimented with them in our lab ahead of time, each module had the same data as the website, QSFPTEK does a great job of making sure the quality of their products is maintained.

This 100G bidi module is a perfect compatibility with my Juniper EX4650 switch, and after comparing several vendors, QSFPTEK's price was the best. The website is also very easy to use and the shopping experience is very good. The sales are also very professional.
