SEPTEMBER 13, 2006 -- Corecess Inc. (search Corecess), a Seoul-based provider of IP broadband access equipment, today unveiled a next-generation DWDM Passive Optical Network (PON) platform that delivers up to 16 Gigabit Ethernet and/or Gigabit Ethernet PON (GEPON/EPON) over a pair of feeder fibers.
Built on company's market existing "S5" optical access platform, which includes advanced optical component and transmission technologies from Electronics and Telecommunications Research Institute (ETRI), gigabit DWDM-PON improves service provider's bandwidth offering in a scalable and cost-effective way, claims the company.
This new platform provides colorless operation by employing Reflective Semiconductor Optical Amplifier (RSOA) technology from ETRI, which is implemented in SFP and GBIC form factors. These plug-n-play optical transceivers provide smooth migration from the legacy optical access platform and carry 1.25-Gbit/sec data streams, which are multiplexed in the off-the-shelf unit. In addition, the highly modular architecture and protocol transparency of WDM favors the new platform as a gradual approach for service providers to meet future service demands for bandwidth and service, say company representatives.
"This launch is Corecess' vision for [a] next-generation optical access platform," explains Yeong-bong Son, executive vice president of sales and marketing at Corecess. "It combines packet's economics and DWDM's bandwidth capability and scalability, while eliminating installation and maintenance woes by utilizing a modular platform, PON architecture, and colorless optical transceivers to improve service provider's capability of bandwidth provisioning economically. Colorless operation is required to make DWDM work for access," he adds. "ETRI's knowledge and technology of advanced optics inspires Corecess to implement new type of gigabit DWDM-PON."
He also notes that scalability and versatility in gigabit provisioning makes this platform fit not only as an optical access node but as back-haul aggregation node for broadband.
