4000 Channels per fibre

Essex Corporation has demonstrated that its Hyperfine Wave Division Multiplexing technology will allow 4000 channels to be transported over a fibre optic cable.

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.
