Rockley Photonics teams up with Southampton University on silicon photonics

Rockley Photonics, a silicon photonics start-up founded by entrepreneur Andrew Rickman, has formed a partnership with the Optoelectronics Research Centre (ORC) at the UK’s University of Southampton to develop integrated photonics technology for mass market applications.

Through the ‘Prosperity Partnership’, Rockley Photonics will match the ORC’s government funding over the next five years. The scheme is designed to strengthen ties between university and industry, and speed up the time it takes innovation to progress from concept to market place.

Calix demos NG-PON2 channel bonding for Verizon

Calix announced that it is the first vendor to demonstrate ITU standards-based channel bonding for NG-PON2, which combines multiple 10Gb/s channels to create a single channel with throughput of up to 40Gb/s.

Channel bonding allows operators to deliver more bandwidth than a single channel can support. This technique is used to boost capacity in DSL and G.fast systems by combining the capacity from several copper cables into a single logical channel. In the case of NG-PON2, the channels are wavelengths running over the same physical fibre.

Coriant conducts disaggregation field trial with Telefonica Germany

Coriant reports the successful completion of a trial to show disaggregated 100G, 150G, and 200G optical transmission over live fibre-optic links in Telefónica Germany’s existing 10G DWDM network.

Conducted earlier this year, the trial showed how an open transmission systems and disaggregated networking technology – in this case using Coriant’s Groove G30 platform – can be used to increase network capacity more than 10-fold, avoiding the need to invest in new fibre.

Infinera trials Infinite Capacity Engine over Canalink cable

Infinera has carried out a successful submarine network field test of its Infinite Capacity Engine (ICE) with Canalink, a wholly-owned subsidiary of the ITER group. Canalink owns a system of undersea fibre-optic cables linking the Canary Islands with the Iberian Peninsula and the western coast of Africa.

The test, which was conducted on Canalink’s 1,393km cable linking the Conil landing point on the Spanish mainland with Tenerife in the Canary Islands, showed that it would be possible to upgrade the subsea cable well beyond its original design capacity.

Back to basics: The fibre-optic connector reinvented

The design of the optical connector hasn’t changed in more than 30 years, but now a company with expertise in precision metal stamping hopes to change that.

California-based nanoPrecision Products has redesigned the optical ferrule, the part that keeps the fibre in position inside an optical connector. Currently made from two ceramic pieces glued together with epoxy, the new design uses metal instead and is much easier to manufacture.

EU to invest €15.5M into PIC packaging and assembly line

The European Union is investing €15.5 million into PIXAPP, a consortium that will establish what is thought to be world’s first open access photonic integrated circuit (PIC) assembly and packaging pilot line. The announcement was made to coincide with the Photonics21 annual general meeting, currently underway in Brussels.

The investment is designed to provide Europe with a state-of-the-art infrastructure that will support the industrial development and manufacture of PICs.

Coriant crunches real-time data to boost optical performance

Finding ingenious, software-driven methods to improve the performance of optical hardware is one of the hot topics at OFC 2017, and every vendor has a unique interpretation.

Optical systems vendor Coriant used the show to unveil a real-time performance and analysis software toolkit that it calls “Coriant Aware Technology”. The new capabilities will increase transmission reach and capacity, enable faster and simpler wavelength planning and provisioning, and improve service availability, the company says.

Nokia and Facebook break subsea spectral efficiency record

OFC 2017, LOS ANGELES – Nokia and Facebook have shown that it should be possible to cram 32Tb/s over a 5,500km submarine cable between New York and Ireland, an increase of two and a half times the cable’s stated operational capacity.

The field trial, which used a Bell Labs invention called “probabilistic constellation shaping” (PCS), also achieved a record spectral efficiency for a submarine cable of 7.46 b/s/Hz.
