Finisar Introduces First 400G QSFP-DD Active Optical Cable

Finisar today announced it will unveil the first 400G active optical cable (AOC) in the QSFP-DD form factor at the Optical Networking and Communication Conference & Exhibition (OFC) 2018, taking place March 13-15 in San Diego, California.

Leveraging VCSEL technology to achieve the lowest power dissipation and lowest cost structure, Finisar’s 400G QSFP-DD active optical cable provides a desirable alternative to copper cables, which cannot scale to the required cable lengths at these high data rates. At OFC 2018, the company will demonstrate the 400G QSFP-DD AOC by running traffic through a Cisco demonstration switch.

“We are pleased to partner with Finisar in this exciting joint demonstration of Cisco’s 36 Port QSFP-DD Demo Platform and 400G QSFP-DD optical module at OFC,” said Ray Nering, Product Line Manager at Cisco. “This demonstration effectively quadruples the aggregate switch bandwidth while maintaining port density, which is critical to support the continuing growth in network bandwidth demand and data center traffic. Cisco expects that QSFP-DD will become the de facto standard for 400G just as other QSFP form factors have done so at 40G and 100G.”
