SEPTEMBER 5, 2008 -- Alphion Corp. (search for Alphion), developer of communication systems, sub-systems, and integrated photonic components based on its proprietary QLight technology, today introduced the PON.ext Release 2 single-rack unit compact system. It is the company's second-generation all-optical GPON extender.
The new PON.ext unit allows carriers to extend network reach to 60 km, increase the number of end users up to 128, and reduce network operating expenditures, say company representatives. The transparent, all-optical system is fully compliant with the recently published ITU-T G.984.6 standard for GPON networks.
"The new GPON extension single-RU pizza box fits into a standard 19" shelf, making it a versatile building block in a variety of GPON network architectures," contends Dr. David Piehler, Alphion vice president of access architecture. "PON.ext technology amplifies signals using all-optical amplification and is transparent to both data rate and protocol. This ensures interoperability with both the Alphion GPON family and other manufacturers GPON equipment," he notes.
The PON.ext rack unit provides 26-dB optical gain for the 1310-nm burst-mode upstream traffic and 23-dB optical gain for the 1490-nm downstream traffic. This enables central office consolidation, services hard-to-reach customers in rural areas, eliminates remote optical line terminals (OLTs), increases network reliability, and reduces carrier operational and capital expenses, says Alphion.
The PON.ext compact system is being displayed at the ITU Asia 2008 exhibition in Bangkok, September 2 � 5, 2008.
