Kaiam to demo 400G QSFP-DD at OFC 2018

Kaiam, a leading manufacturer of advanced data centre optical transceivers, will demonstrate the industry’s highest density 8-lane single-mode 400G transceiver in a QSFP-DD form factor at OFC 2018.

This world class density is enabled by the same innovative LightScale2 architecture used in Kaiam’s XQX5000 series of 100GBASE-CWDM4 QSFP28 pluggables.

The simplified, flattened, non-hermetic LightScale2 platform supports the dense requirements of 8 lanes of 50G PAM4 in a QSFP-DD package with excellent signal integrity and thermal performance. The LightScale2 platform is optimised for high-volume, low-cost manufacturing and flexibly supports both 4-lane and 8-lane 200G and 400G transceiver variants, including 400G-LR8/FR8, 400G-FR4, 2x100G-LR4, 2x100G-CWDM4, 2x100G-4WDM-10, 200G-FR4, and 2x200G-FR4. These can be supported in either QSFP-DD or OSFP packages. The platform can further extend to future 800G solutions, and even beyond pluggables to Kaiam’s innovative Co-Packaged Photonics Interconnect (CoPPhI™).

At OFC 2018, we are demonstrating a transceiver that has 4x the bandwidth of the previous generation in roughly the same QSFP form factor, highlighting the bandwidth and density scalability of Kaiam’s technology. — Bardia Pezeshki, Kaiam’s CEO.

“As capacity and density requirements increase in the data centre, our MEMS-based PLC approach further outperforms traditional approaches,” commented Bardia Pezeshki, CEO. “At OFC 2018, we are demonstrating a transceiver that has 4x the bandwidth of the previous generation in roughly the same QSFP form factor, highlighting the bandwidth and density scalability of Kaiam’s technology.”

“We’re seeing a market need for 400G QSFP-DD transceivers in 2019, but uncertainty and scepticism about whether transceiver vendors can deliver cost-effective solutions at scale with the high speeds needed per lane and the desired reach. Our ability to offer a simple 8-channel 400G solution in advance of the more complex 4-channel electronics, with the full 10km reach, gives the customers faster and easier access to 400G in the desired compact form factor,” commented Jeremy Dietz, VP of Global Sales and Marketing.

The LightScale2 platform leverages Kaiam’s core technologies: Optical Wire Bond (OWB™) hybrid optical integration, and SCOTS™ PLCs. OWB harnesses MEMS to enable hybrid optical integration of best-in-class technologies with high optical coupling efficiency, high parallelism, compactness, robustness, and low cost. Kaiam’s world-class PLCs provide key transceiver optical functions such as wavelength mux/demux, power splitting, and mode size conversion. The fundamental flexibility and extensibility of these core technologies expand the horizon of Kaiam’s product roadmap to 400G, 800G and beyond.
