NOVEMBER 2, 2007 By Stephen Hardy -- Alloptic Inc. (search for Alloptic) has been granted a patent for "Passive Optical Network" technology in the United States (U.S. Pat. 7,272,321). The patent covers a method of carrying TDMA traffic over a PON, for the use of a second wavelength in a TDM fashion over a PON, and for passive fiber rings.
"Alloptic was the early advocate for the carriage of native packet traffic over PONs away from ATM-based solutions and, as such, we were able to 'push the envelope' of what passive optical networking meant and along the way amass ownership of some key intellectual property (IP) for many of the critical components of packet based PON technology," said Shane Eleniak, vice President of marketing and business development for Alloptic, in an email response to Lightwave questions.
"These particular announced US patents, in conjunction with some of our other previously awarded US and China patents, including one for the carriage of variable length packets (Ethernet and IP) over PON, do together cover a broad swathe of the Gigabit PON solutions," he concluded.
