Questions & Answers

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?

Bought it for use in my data center and have been thoroughly impressed with its performance. I tested this transceiver on my Cisco Nexus 9000 series switch and found it to be incredibly reliable with no dropped packets or connectivity issues.

Two months ago, QSFPTEK technicians established a 100G DWDM solution in our plant using 100G SR4 optical transceivers. Out of the available channels, only 4 were utilized, while the rest were reserved for future expansion. The installation went smoothly, and we were able to easily follow the technician's instructions to procure the necessary coherent modules and 100G SR4 optics for subsequent expansion. Since then, our operations have continued without any issues, and we are very satisfied with the quality of service and products provided.

I strongly recommend using these transceivers with MTP cables instead of AOC cables. The benefits of using MTP cables, despite similar pricing, include the flexibility to resize the combination based on the required cable length or transceiver bandwidth.
