PAM4

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…

At OFC 2019, Ray Nering asked me about the single-wavelength 100G PAM4 technology demo we were running, showing clean propagation over 10km of single-mode fiber.     For more details, see Silicon Photonics Demonstration at OFC 2019.  More videos at the Cisco Optics playlist on Cisco’…

Thanks to all who stopped by the Cisco booth at OFC 2019 in San Diego! It was a bustling show and our booth was constantly packed. If you didn’t get to see it, Cisco Optics had a number of products and technologies on display. One of them was Cisco’s silicon photonics platform that our t…
