Ranovus to demo 200G quantum dot laser transceiver


Canadian start-up to demonstrate 400GB/s transmission over 80km with ADVA Optical Networking

Ranovus, a start-up providing multi-terabit interconnects, has launched its 200G On-Board Optics and CFP2 optical transceiver solutions for 5G mobility and data centre interconnect (DCI) applications. These are based on the company's multi-wavelength Quantum Dot Laser (QDL), ring resonator based silicon photonic (SiP) modulators, driver ICs as well as receiver building blocks.

Ranovus' products are now in lab trials with multiple optical networking equipment vendors, including ADVA Optical Networking which has worked with the company to demonstrate 400GB/s transmission over 80km.

"Our demonstration will feature transmission of 400Gb/s in an FSP 3000 CloudConnect terminal and over 80km of standard single mode fibre utilising our open line system," said Christoph Glingener, CTO/COO at ADVA. "In partnership with Ranovus, we have made impressive progress to validate direct detect technology as an effective way for data centre operators to lower their cost per bit and improve energy efficiency."

The Quantum Dot Multi-Wavelength Laser (QD MWL) is a semiconductor laser that uses self-assembled quantum dots to generate multiple wavelengths simultaneously from a single device.

A single QD MWL device can provide up to 96 wavelengths in the C-band alone, allowing for the replacement of 96 individual lasers in an equivalent system.

According to Ranovus, QD MWL based solutions allow for a much simpler and compact interface design, resulting in lower power consumption and better performance when compared to an equivalent solution having multiple discrete lasers and components. The advantage of a QD MWL is its ability to provide multiple wavelengths simultaneously, each of which can be selected and used as a light source for data transmission at 25 Gb/s and beyond.

"In today's data driven economy, the unprecedented growth in the data traffic cannot be efficiently addressed in terms of cost and power by yesterday's technologies. We are very excited to bring the next generation of scalable and miniaturised multi-wavelength Quantum Dot Laser and Silicon Photonics platform technologies to support the data growth curve," said Hamid Arabzadeh, chairman and CEO at Ranovus.

"After a series of successful trials over the last year we are pleased to announce the general availability of our product portfolio that enables scalable multi-terabits bandwidth connectivity in form factors that consume less power and are at a third the cost of coherent and half the cost of other PAM4 direct detect transceivers per Gb/s."

"Our impressive product demonstration with ADVA includes transmission of live traffic over Ranovus' on-board optics integrated into the FSP 3000 400G terminal, as well as Ranovus' 200G CFP2 modules over the same physical layer for 80km of transmission distance." said Saeid Aramideh, co-founder and chief marketing & sales Officer at Ranovus. "We would like to extend our gratitude to the team at ADVA for their tremendous support and partnership over the years to bring our innovation to market deployment."

Ranovus was founded in Ottawa February 2012 and has received financing from leading venture capital firms including Azure Capital Partners, Deutsche Telekom Venture Funds, BDC Capital, OMERS Ventures, MaRS Investment Accelerator Fund, Export Development Canada, and funding from Sustainable Development Technology Canada.
