First 50G-PON merchant silicon spurs operator trials

Broadcom has unveiled the industry’s first merchant silicon for the 50-gigabit passive optical network (50G-PON) access standard. Until now, only access equipment players such as Huawei and ZTE had their own 50G-PON silicon.

Broadcom has announced two 50G-PON devices: an optical line terminal (OLT) chip and the optical networking unit (ONU) 50-PON port to the users.  Both chips include custom hardware from Broadcom to run artificial intelligence (AI) machine-learning algorithms. 

Jim Muth, senior manager of product marketing at Broadcom, says supporting AI benefits the operator and the quality of the end user’s broadband service.

ADVA enables the sharing of spectrum at the optical layer

• Spectrum-as-a-service enables third parties to run networks over existing optical infrastructure.

• ADVA has also simplified linking systems to the metro-access network using self-tuning SFP+ optical modules.

ADVA has developed a scheme whereby communications service providers can sell unused fibre capacity to customers to design and run their own optical networks.

“Optical spectrum-as-a-service gives communications service providers tools to sell spectrum to someone else who now doesn’t need to build a parallel infrastructure,” says Jörg-Peter Elbers, ADVA’s senior vice president, advanced technology, standards and IPR.

ADVA has also developed a G.metro-compliant dense wavelength-division multiplexing (DWDM) scheme to simplify linking business parks, radio cell towers and small cells to a metro-access network.
