AUGUST 13, 2008 -- Alloptic (search for Alloptic) today announced that it has been granted a patent by the Japan Patent Office for "Point-To-Multipoint Passive Optical Network That Utilizes Variable-Length Packets" (No. 2002-546329284479).

Fiber-to-the-home (search for FTTH) and fiber-to-the-business PON systems carry variable-length IP or Ethernet packets, which often must be fragmented and encapsulated into fixed-length frames for transmission. This patent applies to the way in which that critical function occurs in popular PON technologies that are deployed not only in Japan, but also around the globe, say company representatives.

Japan is the fourth country to affirm Alloptic's intellectual property rights for this technology, adding to the list of similar patents held in the United States (U.S. Pat. 7,031,343), Taiwan (#90128223), and China (#ZL01821736.2).

"We are pleased to receive this patent," contends Ric Johnsen, Alloptic's president and CEO. "The broad geographic protection we received for our intellectual property is a testament to the innovation and contributions Alloptic makes to the communications industry," he says.
