QSFP28

Subscribe to the Cisco Optics Blog We recently introduced the QSFP28 100G FR pluggable transceiver. This may be one product, but it’s the beginning of a bigger industry dynamic that will change 100G pluggable optics over the next several years. To understand why we will need a change, let̵…

When it comes to network deployment strategies, you may be accustomed to treating pluggable optics as an afterthought. But over the past several years, higher data rate pluggable optics have been developed to keep up with bandwidth demands in data centers and service provider networks. And with thos…

Data center traffic is expected to quadruple in the next five years as IoT and big data applications take off. At the same time, we’ll see growth in distributed databases and applications, increasing virtualization and virtual machine density. And all this comes with more complex and unpredictable t…

In earlier blog posts (Looks Like We’re Upgrading Again! Dual-Rate 40G/100G BiDi Transceiver and 40/100G QSFP BiDi Transceiver’s Backward Compatibility With 40G BiDi), we introduced the dual-rate 40/100G QSFP BiDi transceiver and described how Cisco uniquely offers 40G capability and backward compat…

We mentioned recently the new dual-rate 40G/100G BiDi QSFP28 pluggable optic transceiver module. Like the single-rate 40G BiDi, it lets you seamlessly upgrade short reach links from 10G without having to replace duplex LC-connectorized MMF fiber infrastructure originally meant for 10G SR. But that&#…

It’s hard to believe that only four short years ago the data center industry saw the introduction of the QSFP+ 40G BiDi pluggable optical transceiver, which broke the mold by providing 40Gb connectivity over the same fiber format (dual MMF) as 10G SR. Until then, 40G SR4 was the primary option, and…

You may have heard of Forward Error Correction (FEC), since it’s used in many forms of data communication. You’ll find it in wireless networks, space communication, undersea fiber optic networks, bar code scanners, and your CD player (if you still have one). We’ll talk more about FEC in a subsequent…
