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

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.

I'm thrilled to report that the BER of this product is exceptionally low, meeting our performance requirements and exceeding expectations. It's the perfect choice for building a rock-solid network environment, ideal for our high-load scenarios.

Wendy's customer support service is perfect, always responds promptly to our questions and provides us with technical support, which is what we need, for certain parameters of the product, sales always gives us the right answer quickly, QSFPTEK staff is very technically competent.

This is a reliable module, its packaging effectively protects it from damage during transportation, plug and play, and can provide a stable connection between my devices. It is also well priced, and overall it is a very good shopping experience.

I received the item the fourth day I placed the order, it's quick and smooth. The module is well-packaged and nicely built. Thanks for your recommendation, their price and service are wonderful!
