      This 40G QSFP+ module provides consistent performance and very low latency. It was easy to install with our Cisco switches. It's an excellent choice for mid-scale data center upgrades and high-bandwidth aggregation links.

      Before purchasing, we asked QSFPTEK about the products of ultra-long distance transmission solution, QSFPTEK engineers recommended us OTN and MUX two kinds of solutions, which are very professional and friendly, and finally we chose 40G ZR4 and QT860 series together. Thank you very much for the help from QSFPTEK engineers!
