Questions & Answers

What is the difference between using 4x100 vs 8x50 of 400G QSFP-DD transceivers?

The main difference is that the optical signal transmission method, 4x100G means transmitting optic signals in 4 channels, and 100G each channel, while 8x50G is transmitted optic signal in 8 channels, and 50G each channel.
What's the meaning of ''DR4''?

''DR'' means that the 500m transmission distance and using Singlemode fiber, ''4'' implies there refers to 4 optical channels. The 4 independent optical channels inside the DR4 modules transmitting data on separate fibers make up a total of 8 fibers(4 Tx and 4 Rx). Each of the optical channel transmission rates is 100Gb/s.

To trial a 400G connection between our Cisco Nexus 3000 switches, we required multiple 400G optical transceivers. Before placing the order, I consulted my account manager regarding compatibility concerns. Fortunately, the QDD-400G-DR4-S transceivers we purchased were fully compatible with our switches, and we have not encountered any issues thus far.

A few years ago, we collaborated with QSFPTEK to deploy our 10G network, primarily because their products were cost-effective. I never thought that I could depend on QSFPTEK for our high-speed transmission needs as well. To my surprise, QSFPTEK continued to make progress, and their 400G modules and MTP cables worked seamlessly with our Cisco switches, resulting in a smooth 400G direct connection.

Our goal was to upgrade our network system to achieve higher speeds, so we opted for a 400G upgrade and needed to select appropriate transceivers. Since we didn't require long-distance transmission, the 400GBASE-SR8 transceivers were the perfect fit for us. Initially, we were apprehensive that these modules might not be compatible with our Cisco switches, but to our delight, they exhibited outstanding connectivity, and all performance metrics were within normal parameters. I highly recommend them!

Ordered items for a very important project for the company. The inventory is sufficient and the service attitude is good, and it works well with the company's switches.

I finally received it after 2 weeks, it's very easy to use, faster and more energy efficient than buying other transceivers before.
