What is the laser level of 100G SR4? Can you provide a test report of the laser level of this module?

Class I. Of course, you can contact our sales to get the report.
The transmission distance is less than 550m, should I use multi-mode?

I'm afraid you should purchase the single-mode optics, like 100G LR4.
What is the Packaging Technology of the 100g lr4?

We purchased this optical module here and one switch from another vendor. The module has very good packages and has been delivered quickly, but our network switches are on the delivery way...

After receiving the module, we inspected it and found no visible signs of use on Goldfinger. Following this, we proceeded to test it and confirmed its normal functionality on the QFX5200. It is worth noting that the performance of this batch of modules surpasses its price.

Recently, I am building a company network. Due to the limited budget and the brand module is too expensive, I chose QT. At first I just bought a few modules for my Arista 7280CR2-60 to test the connectivity, and I am very satisfied with the speed of delivery and express delivery. After testing, these modules are as perfect as the account manager said, all I need to do is plug the module into the device and connect the fiber.

Bought some 100G modules for my Cisco Nexus N3K-C3232C, it is just as in the introduction, with good quality and stable transmission performance. When I connect these modules to my device, it is recognized by the device immediately. A very good shopping experience, and my account manager responded very promptly.

My device is a Dell S4148T-ON, and since I bought it for the first time, I am worried about its compatibility. After asking the account manager, she said that she can help me test whether it is compatible. Soon she sent me a test report, this module works great on my device,
