Broadlight Gets GPON Patents

SANTA CLARA, Calif. -- BroadLight, the leading supplier of GPON semiconductors and software, today announced that it has received a U.S. patent, number 7,370,127, which enables high-speed interconnect communication in a GPON design. BroadLight has already secured Intellectual Property throughout the GPON System and the addition of this patent further strengthens its competitive position.

“BroadLight’s systems-level expertise in GPON enabled us to redesign the internal bus architecture to provide a significant increase in performance,” said Dudu Avishai, Director of VLSI for BroadLight. “This is extremely advantageous to our customers who need to deliver the highest bandwidth possible in a GPON design so that service providers can deploy true Triple Play.”

The patent describes internal bus architecture capable of providing high speed inter-connection and inter-communication between modules connected in an integrated circuit. This innovative concept enable none blocking with virtually unlimited capacity of data traffic between peripherals and processing elements without the penalty of complex backend flow in SoC design.

In a separate release:

SANTA CLARA, Calif. -- BroadLight, the leading supplier of GPON semiconductors and software, today announced that it has received a U.S. patent, number 7,356,058, which enables the implementation of burst mode laser driver for PON applications in a standard CMOS silicon process. BroadLight has already secured Intellectual Property Rights throughout the GPON system and the addition of this patent further strengthens its competitive position.

“BroadLight’s optical transceiver expertise in PON enabled us to design the burst mode laser driver in a standard CMOS process and to demonstrate its performance,” said Igor Elkanovich, VP of VLSI for BroadLight. “This allows us to plan a breakthrough and unique level of integration between the PON SoC and its optical front end.”

This patent outlines an adaptive laser diode driver capable of driving various laser types as well as accommodates the variations in lasers for ensuring optimal optical performance and calibration during manufacturing and operation over lifetime and temperature variations. The driver adaptively conditions output modulation and bias signals for optimal laser operation. This adaptive laser diode driver can be integrated in optical line terminal (OLT) or optical network unit (ONU) devices.
