BroadLight’s GPON ICs: from packets to apps

What is being announced?

BroadLight has announced its Lilac family of customer premise equipment (CPE) chips that support the Gigabit Passive Optical Network (GPON) standard.

The company claims its GPON devices with be the first to be implemented using a 40nm CMOS process. The advanced CMOS process coupled with architectural enhancements will double processing performance while improving five-fold the packet-processing capability.  The devices also come with a hardware abstraction layer that will help system vendors tailor their equipment.

"Traffic models and service models are not stable, and there are a lot of differences from carrier to carrier"

WDM-PON: Can it save operators over €10bn in total cost of ownership?

Behind the numbers

Source: ADVA Optical Networking

“The focus of operators to squeeze the last dollar out of the system and optical component vendors is really nonsense.”

Klaus Grobe, ADVA Optical Networking.

Key findings

The total cost of ownership (TCO) of a widely deployed WDM-PON network is at least 20 percent cheaper than the broadband alternatives of VDSL and GPON. Given that the cost of deploying a wide-scale access network in a large western European country is €60bn, a 20 percent cost saving is huge, even if spread over 25 years.
