Cisco QSFP-100G-DR-S Compatible 100GBASE-DR Single Lambda QSFP28 1310nm 500m LC Duplex SMF DDM Optical Transceiver Module

This 100GBASE-DR1 module provides very reliable performance for sending data over a distance of about 500 meters using a single wavelength. The module is very good at managing heat and works well with other components. It's great for sending high-quality video and audio over short to medium distances.

We needed to set up a new 100G link between a Cisco Nexus 9336C-FX2 (spine) and a 93180YC-EX (leaf) in our data center. Buying a stack of genuine Cisco 100G-DR modules was out of our budget for this project. We ordered a few of these compatible ones to test first. We plugged it in, and it was recognized immediately as a QSFP-100G-DR-S. The link negotiated without a single hiccup. Have been running it for weeks now under production load, and it's been performing identically to the official ones. Huge cost savings without any compromise on performance or reliability. A no-brainer for any enterprise looking to scale cost-effectively.

I got this 100GBASE-DR1 for a short-run single-mode setup, and it's been working perfectly. The speeds are exactly what I needed, and there have been no drops or other technical issues. It just snaps right in and works. It does get a bit warm if you use it all day, but not too warm. Honestly, for the price, I would buy it again without hesitation.

We are impressed by the stability and performance of this 100G QSFP28 module. It smoothly handles large data loads and works seamlessly with our Cisco equipment. It's a solid option for high-speed backbone or cloud applications.

Used with Cisco C9500-32C with no issues for about one month so far. The switch recognizes the optics immediately and the connection is reliable. For anyone with hesitations, I think it is worth a try.

This 100G DR module can be used with 400G QSFP-DD DR4. QSFPTEK provides the basic solution for our 400G infrastructure network, which helps us a lot to upgrade our network.

Great product, delivery to only took 4 days, and of course the cooperation of customer service Talia, who helped me keep track of my order and updated me in real time, great shopping!

I do love the customer service they provide. I sent my tender document and inquired about the product recommendation, and they responded to me with detailed quotation lists. Also, my sales rep. is kind and professional, she can always get my point, the communication process is going smoothly. The product is reliable and cost-effective with five stars!

QT's product quality is just as good every time, or even better! I had some issues with the module before, and they have already dealt with it in this order. I am amazed at how quickly they deal with the problem! I will continue to trust QT in the future!

Not the first time to buy QSFPTEK products. They seem to have the same performance as the ones I bought before.
