Only 6 months after the launch of its 100Gbps DWDM transceiver product family in March 2016, EFFECT Photonics is now demonstrating the ability to achieve 500Gbps using PAM-4 (4-level Pulse Amplitude Modulation) up to 75km, with its Optical ‘System-on-Chip’ photonic integration technology. This is the result of ongoing collaboration with the Technical University of Eindhoven, with further developments in the pipeline.

With Internet traffic expected to grow at an annual rate of 22-25% until 2020, the majority of this growth is coming from interconnecting Data Centres and in the Metro-Access segments. The need to reduce cost, power, and size continues to be a major driver of product innovation.

EFFECT is addressing this need with its Optical ‘System-on-Chip’ photonic integration platform by combining all of the optical functions into a single chip, and packaging this with its own low-cost ‘gold-box free’ packaging technology. The optical functions include: multiple DBR lasers, low-voltage drive MZ modulators, AWG, and wavelength monitoring, all within the single chip.

The powerful combination of EFFECT’s Optical ‘System-on-Chip’ photonic integration platform, unique low-cost packaging, and PAM-4 ticks all the boxes, reducing cost, power, and the physical size of the module – all this without the need for more expensive long-haul coherent optical transceivers.

VP Sales and Marketing, Robert Hughes commented “We knew very early on that combining many optical functions into a single ‘System-on-Chip’ offered a real alternative in the industry. This integration together with our novel packaging technology allows us to differentiate ourselves in the DCI and Metro-Access part of the network.”
