Cisco Optics are now qualified on Cisco UCS servers even when using 3rd party NICs such as those from Intel, Mellanox, and QLogic. This is a significant development for data center operators who are more and more reliant on cables and pluggable optics as SFP and QSFP technology progress, and cloud applications dominate.

Since the introduction of 100G pluggable optics several years ago, a great variety of reaches and form factors became available. Among the most confusing reaches are the Extended Reach variants. In this blog, we are going to explain what variants are available in the Cisco Optics portfolio, and the differences between them.

Learn how the QSFP28 FR pluggable optic paves the way to 400G upgrades and how it impacts the network performance and deployment process in this next entry in the Single Lambda 100G blog series.

Here's how to ensure your 100G optics are forward compatible. It's all about simplifying designs and standards so that manufacturers can support volumes equivalent to today's 10G SFP+ pluggable optics. The key is to use single-lambda 100G.

The Single-Lambda 100G optics standards will be instrumental in the development of the next generation of 100G pluggable optics.

A new 800G MSA is formed to support continued growth in traffic demand and the resulting need for higher link data rates in data centers. Once again, Cisco is there at the forefront.
