Comprised of field hardened dense wave division multiplexing
(DWDM) optical passives, node-installed EDFAs and optical switches, the VHub allows MSOs to configure hub sites within a compact strand- or pedestal-mounted housing.
CIR's data suggests that while OC-192 SONET/SDH transport will remain the largest spending category over the forecast period starting in 2004, technologies such as Wave Division Multiplexing
(WDM), 10 Gbps Ethernet and 10 Gbps ATM will achieve more significant growth rates.
The network will possess optical wavelength capacities from 10 gigabytes up to 320 gigabytes by applying Dense Wave Division Multiplexing
(DWDM), transmission capabilities and Layer three routing architecture.
A higher frequency version is under development, featuring PECL (positive emitter coupled logic) output in the following frequencies: 10 gigabit Ethernet (156.25 MHz, 312.50 MHz); Fibre Channel (212.50 MHz) or WDM (Wave Division Multiplexing
) (622.08 MHz).
While constantly monitoring all new developments in Internet technology, LINX has rejected the idea of adopting Dense wave Division Multiplexing
(DWDM) - a system that increases the carrying capacity of optical fibre cables.
The partnership involves Marconi's high speed DWDM - dense wave division multiplexing
- technology and network management.
(Milpitas, CA) has acquired Cisco Systems, Inc.'s (San Jose, CA) Dense Wave Division Multiplexing
(DWDM) multiplex, demultiplex and add/drop optical module manufacturing capabilities in West Columbia, SC.
The optical multiplexing technology being used today for metropolitan area connectivity for the enterprise is Wave Division Multiplexing
(WDM) or its more current adaptation, Dense Wave Division Multiplexing
Lucent Technologies, Murray Hill, N.J., has reached an agreement with Japan Telecom to supply its dense wave division multiplexing
(DWDM) optical networking systems.
The system's technology supports high-bandwidth storage applications and allows for interoperability with existing GbE (Gigabit Ethernet) DWDM (Dense Wave Division Multiplexing
) and FC (Fiber Channel) products.
Marconi will supply to Telecom Italia its Smart PhotoniX Dense Wave Division Multiplexing
(DWDM) system, which multiplies available band-width forty-fold and increase traffic speed four-fold on both fixed and mobile lines, according to the British group.
Numerous projects are under way to investigate ways of splitting light into its various color components and sending different information on each color band (wave division multiplexing
) or of compressing digital information with advanced techniques that compress at 500:1 and only transmit information that has changed in a video scene or document.
