Silicon Line Raises €8.2m/$9.5m in Series B Funding Round Led by Capital-E

World Leader in Ultra-Low-Power Optical Link Technology to Invest in Ramping up Production, Expanding its Design Team and Setting Up Local Support in Asia

Antwerp, September 10, 2018 – Silicon Line GmbH (, the global leader in developing and providing innovative ultra-low-power optical link solutions for the consumer electronics as well as the commercial and industrial markets, has raised €8.2 ($9.5m) in a Series B financing round led by Capital-E .

Additional investors in the Series B round include LRM,  Munich Venture Partners and Unixtar. The proceeds will be used to ramp-up production of the company’s optical modules – tiny circuit boards inside cable connectors; for upgrades to the company’s component factory located in Hasselt, Belgium; for the hiring of additional design engineers; and for the opening of local customer support offices in Asia.

Capital-E, LRM and Munich Venture Partners are existing investors from the company’s Series A round which closed in March 2015 and raised a total of €23m ($26.78m). Unixtar, one of the company’s contract manufacturers, is a new investor.

In many high-speed data applications, copper wire cables are reaching their physical limits in terms of connectivity – especially true for distances greater than one meter. Ultra-low-power optical link technology represents the path ahead for a broad range of consumer electronics and industrial applications. According to some market research estimates, the optical interconnect market will reach $7b by 2020.

Other market drivers are:

  • the proliferation of personal, portable devices – including phones, tablets, notebooks, augmented and virtual reality headsets and more – placing a premium on thin, flexible, lightweight cables that minimize power consumption and susceptibility to electromagnetic interference;
  • specialized camera applications in healthcare, scientific research, national defense and other markets; and
  • size and weight considerations in a broad range of consumer/industrial segments including automotive, motive and aviation.

“The team has built a formidable portfolio of technologies and products which are already influencing current and future product developments in North America, Asia and Europe,” said Ruud van der Linden, CEO, Silicon Line. “We’re grateful to our funding partners – past and new – who are providing the resources required to allow the company to expand and capture the market opportunity we have created.”

“In much the same way where copper cables began to collapse in datacenters, there is now a significant role to play for active and passive optical cables in consumer and automotive electronics. Silicon Line has the critical components at scalable pricing levels to make this transformation to last.”, said Pascal Vanluchene, Partner, Capital-E.

“Silicon line has achieved a great breakthrough on a high-tech market. As an investment company, we are very pleased to be able to give such a fast-growing company, operating from Corda Campus in Hasselt, Belgium, the extra boost they need”, said Lieven De Jonge, Head of Smart Manufacturing, LRM.

“Silicon Line’s team has realized a remarkable breakthrough technology platform enabling many applications for international markets, such as consumer electronics, medical devices, industrial and new virtual reality/augmented reality,” said Rolf Nagel, managing director, Munich Venture Partners.
