Wendy answered many of my questions and was always very responsive whenever I emailed her. I asked about the specs of the product and she sent me a complete spec report that was identical to what was shown on the website.

I bought three compatible modules from Cisco, Juniper and Arista. The delivery speed was very fast and the account manager also gave me feedback on the logistics information in time. It is plug-and-play, compatible and stable, and the transmission is also very stable, and it can achieve the expected transmission rate, which is great.

This 25 SR optical module is good quality to use, I receive it only in three days, amazing shopping experience!

The express was very fast and it was delivered to my address in three days. The product was well packaged so I didn't have to worry about it being damaged during transportation. It was plug and play, no additional configuration required, and overall it was a good shopping experience.

We required SFP-25G-LR modules for our data center setup. Our switch brand is Cisco, and the original product was considerably pricey. However, these 25G transceivers not only successfully passed our rigorous performance tests but also seamlessly integrated with our switches. This product has certainly exceeded our expectations, earning a resounding thumbs up from our team.

The 25G SR modules I purchased were an excellent choice for my network. They provide reliable and high-speed connectivity, and I love the fact that I can upgrade to 100G in the future without removing them.

I was hesitant to purchase these switches from QSFPTEK Inc. because the price seemed too good to be true, but I'm happy to report that they are exceeding my expectations.

We recently integrated the 25G module into our network, and the results have been outstanding. The module has greatly enhanced the performance of our network, providing lightning-fast speeds and low latency.

With its low power consumption and advanced features, the 25G SR SFP28 module offers a high-performance, cost-effective solution for network upgrades, making it an ideal choice for businesses looking to improve network efficiency and performance.

The 25G SR SFP28 module is designed for use in data centers, enterprise networks, and service provider networks. It is compatible with a wide range of network switches and routers, providing flexibility and scalability for network upgrades and expansions.
