Delivery was fast and the 40G ER4 optical transceivers performed exactly as expected. We regularly require 40G modules, but many previous suppliers faced inventory shortages or slow delivery times. QSFPTEK has proven to be dependable and efficient, making them a great partner for our networking needs.

We were looking to upgrade our 10G network to 40G but weren't sure which solution would work best. I reached out to QSFPTEK for advice, and they suggested using these 40G ER4 modules with pre-terminated cables. It turned out to be a more cost-effective and scalable option for our setup.

This module works seamlessly with my Cisco C9500-24Y4C switch, and I was worried about compatibility before I purchased it. Sales Yanny provided me with a test report of the product, along with some other documentation, a great shopping experience.
