Cisco SFP-25G-LR Compatible 25GBASE-LR SFP28 1310nm 10KM DDM LC SMF Optical Transceiver Module

Our servers have been running the 25GBASE-LR module smoothly for weeks now. It is easy to plug in and is instantly recognised by the system. The transmission quality is stable over 10 km and I haven’t noticed any packet drops. It is slightly warmer than I expected, but still within normal limits. Overall, it's great value for money.

Been running this 25G LR module in my lab switch for a couple of weeks, and it's been working great. The link came up right away and has been working well over a 10-kilometer fiber run. The heat is a bit higher than I expected, but it doesn't affect performance. For the price, it's a very reliable choice.

It's easy to use my equipment with it. The Signal is stable, and it feels like it can take a beating. My only complaint is that the box could've had better padding, but it arrived in good condition anyway. This 25G module works exactly as it says it does.

It can achieve the expected transmission distance, the transmission is stable, and the performance is excellent. This is a great module. The account manager responded to my questions in a timely manner, and the express delivery arrived on time as expected.

Using this 25G SFP28 LR on my Cisco WS-N9K-C93108TC-EX switch, no errors were reported, very easy to use, plug and play. Also purchased the matching LC optical fibre from the website, overall a very easy shopping experience and you can quickly find other products you need.

I highly recommend these optical modules to anyone looking for a reliable and cost-effective networking solution. They are plug and play and allow for future upgrades without breaking the bank.

I tested the Cisco 25Gbase-LR SFP28 transceiver on my Nexus 93180YC-EX switch and it surpassed my expectations. The module is easy to install and offers reliable, lightning-fast data transfer speeds. The build quality is exceptional, making it a great investment for anyone looking for a high-performance network solution.

I recently obtained multiple 25G SFP28 modules from QSFPTEK and found them to be comparable to Cisco's own transceiver modules, with the only noticeable difference being the more affordable price of the third-party transceivers. Delivery was prompt, and the modules were highly functional straight out of the packaging, working seamlessly with my Cisco C9500-24Y4C switches. I would definitely consider purchasing from QSFPTEK again for any future needs.

I purchased a 25G optical module for my Cisco N9K-C93180YC switch. QSFPTEK AM confirmed the module's compatibility before I placed the order. Upon plugging the module into the switch's port, it was able to read the module's TX and RX power.

The 25G SFP28 module purchased a week ago works fine on my RUIJIE 6700 series switch. These high-performance products help us achieve seamless data center connectivity at a low price. We are satisfied.
