November 14, 2007 -- BroadLight (search for BroadLight) has secured a new U.S. patent, number 7,288,983, which it says covers techniques that enable its products to exceed GPON performance requirements over the industrial temperature range. With the addition of this recent patent, BroadLight asserts it now holds IP throughout the GPON system, giving it a significant competitive advantage and technology leadership position.
The patent is for a novel approach providing accurate temperature compensation of 2.5-Gbit/sec mixed-signal circuitry and allows robust GPON signal transmission over the entire industrial temperature range (-40oC to +85oC). BroadLight says the approach provides its chips with a high level of integration and the ability to exceed standard jitter requirements over the temperature range without using external components. High jitter tolerance and low jitter generation enable robust GPON signal transmission using low-cost optical transceivers, the company concludes.
