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?

QSFP28 form factor allows for higher port density on network switches, which means more connections can be made in a smaller space. Qsfp28 can help me save space.

Due to project requirements, some 100G SR modules are needed for testing. But because the time is very urgent, the delivery period should be shortened as much as possible. After communicating with QT's account manager, she can help me deliver the goods as soon as possible, and choose the fastest possible express method. So on the third day, I received my purchase. Thanks to my account manager for not having to delay my project.
