FS Launches Affordable SiPh-Based Transceivers for Energy-Efficient 400G Data Centers

May 11, 2021

May 11th, FS News - FS is excited to declare the release of QSFP-DD 400GBASE-DR4 silicon photonics transceiver. Designed with highly integrated silicon photonics and industry leading Broadcom DSP chip, the new QSFP-DD DR4 transceiver will enable a more economic and energy-saving solution for high-bandwidth data communications.

The new FS QDD-DR4-400G-Si transceiver solution has the following key features:

  • The new transceiver is integrated with industry leading high performance and low power Broadcom 7nm DSP chip. The power consumption of the transceiver can be lower than 10w. It improves the performance of hyperscale data centers with power efficiency.

  • QDD-DR4-400G-Si transceiver features SiPh-based design. By integrating Driver/TIA/PD/MZM using silicon photonics, the transceiver with a smaller footprint achieves the benefits of lower power consumption, affordable cost, and higher bandwidth. Through passive alignment for optical coupling and advanced COB and 3D packaging, the manufacturing process is simplified and mass production is ensured.

Over the recent decades, silicon photonics has been deployed in diverse applications and shows its benefits. As the need for higher speed of today's hyperscale data center interconnects grows, silicon photonics technology is expected to break the bottlenecks (high cost, high power consumption, and small production scale) of today's high speed optics. According to the forecast of Lightcounting, the share of SiPh-based transceivers is going to grow in the following years and will increase to 45% by 2025.

"The new SiPh-based transceiver is the latest example of how FS helps to meet our customers' expectations for affordable high-bandwidth applications." Says Andy Gao, the product line manager of transceivers at FS.com. " It is a more beneficial alternative than traditional 400G optics to facilitate the transition to 400G high capacity and will become a promising interconnect solution in the trend of heavy investment in data centers."
