With an advancement that will dramatically increase fibre capacity, Essex Corporation has demonstrated that its Hyperfine Wave Division Multiplexing (HfWDM) technology will allow 4000 channels to be transported over a fibre optic cable.
The Essex Hyperfine technology improves the data-carrying capability of the fibre by factors of 5 to 20 by carrying data with a much more narrow channel spacing than existing systems.
‘The Hyperfine module divides standard DWDM channels into 50 to 100 one GHz channels. This result will enable Hyperfine systems to have a significant impact on the metro and last mile problems,’ stated Len Moodispaw, Chief Executive Officer of the company.
‘The HyperFine ADM can be designed in various modes, including a single fixed channel add-drop, single tunable channel add-drop, multiple ganged channels add-drop (fixed or tunable), and fully programmable add-drop. An example application is a SOHO (small office/home office) HyperFine ADM that can receive Gigabit Ethernet channels directly from an all-optical network,’ added Terry Turpin, Essex Chief Technology Officer.
Essex has filed several new patents for the new technology with the US Patent Office. A provisional patent has been filed for both its add/drop multiplexer) and its Optical Code Division Multiple Access technology (OCDMA).
A full patent application for its Optical Processor Enhanced Receiver Architecture (OPERA), a system that combines an optoelectronic processor with advanced multi-user detection algorithms to eliminate the ‘near-far’ problem for a CDMA system, was also recently filed.
