Alloptic's Passive Optical Network Receives Japanese Patent

By Jayashree Adkoli, TMCnet Contributor


Alloptic (News - Alert), a provider of RF-over-glass and passive optical networking solutions for cable TV, telecom, and private network operators, announced that the company has been awarded a new patent for “point-to-multipoint passive optical network that utilizes variable-length packets,” by the Japanese Patent Office.
 
For those who are new to PON concept, passive optical network is a point-to-multipoint fiber to the premises network architecture in which single optical fibers are enabled to serve multiple premises by utilizing un-powered optical splitters.
 
PON systems such as fiber-to-the-home and fiber-to-the-business carry variable-length IP or Ethernet packets. Theses variable-length IP or Ethernet packets have to be transformed into fixed-length frames for transmission, which can be achieved by fragmentation or encapsulation. The new patent is a technique that is utilized for such critical function that mainly occurs in well-known PON technologies.
 
Alloptic’s new patented technique is not only deployed in Japan but in other parts of the world as well. According to Alloptic, Japan is the fourth country to encourage this technique and is also an addition to the list of similar patents held in the United States, Taiwan and China.
 
Alloptic says that it is the first company to develop an Ethernet-based PON product. The company’s solutions utilize industry-standard protocols and architectures along with advanced technology to deliver gigabits of bandwidth to residential and business users.
 
“We are pleased to receive this patent,” said Ric Johnsen, Alloptic president and chief executive officer. “The broad geographic protection we received for our intellectual property is a witness to the innovation and contributions Alloptic makes to the communications industry.”
 
Livermore, California-based Alloptic provides a comprehensive suite of emerging and legacy services for a complete range of voice, data, and video applications. The company also develops and delivers optical access solutions, which facilitates cable TV, telecom, and private network operators to offer converged, communications, entertainment, security, and automation services for both businesses and residential customers.
