The QSFP+ 40G CSR pluggable optic offers an alternative to 40G BiDi, especially when longer reach is needed.

There's a new addition to Cisco's Single-Lambda 100G series of QSFP28 optics that provides 10km reach. It's called 100G LR.

Optimized for data center applications, the QSFP28 100G DR is the second product in Cisco's Single-Lambda 100G portfolio of pluggable optics.

The re-branded Ethernet Technology Consortium has released a specification for 800G signaling. This goes hand in hand with the new QSFP-DD800 form factor MSA.

The new QSFP-DD800 form factor MSA lays the foundation for 800G Ethernet pluggable optics.

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.
