Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :ADCT ADCT Adaptive Discrete Cosine Transform ) (www.adc.com) today announced that it has expanded its industry-leading PONy Express pony express, in U.S. history, relay mail service. At its inception in Apr., 1860, the pony express operated between St. Joseph, Mo., the western end of a telegraph line, and Sacramento, Calif. [TM] access transport platform with a new WDM-PON application that enables service providers to meet the demands for increasing bandwidth by maximizing their fiber capacity. This solution will be featured at NXTcomm, June 16-19, Las Vegas, in ADC's booth #3916. In this application, the PONy (Passive Optical Network over wavelengths) Express, the first transport platform to address the bottleneck that occurs in traditional optical access networks, is combined with a Wavelength-Division-Multiplexed Passive Optical Network (WDM-PON) Plug-and-Play Splitter in a fiber distribution cabinet to provide an easy upgrade from Gigabit PON (Passive Optical Network) An optical point-to-multipoint access network. There are no optical repeaters or other active devices in a PON, hence the name "passive. (GPON) to WDM-PON with minimal service impact. "Service providers worldwide are deploying PON, including GPON, to provide the bandwidth that consumers and enterprises demand," said Jon Norton, vice president of Network Solutions for ADC. "However, GPON can't meet long-term bandwidth requirements and WDM-PON provides a future-proof solution because its initial per-subscriber capacity of 100 Mbps is more than enough to support the most bandwidth-intensive applications and services." The PONy Express enables cost-effective access to business parks, campuses, and multi-dwelling unit/multi-tenant units over a shared network infrastructure without sacrificing security or limiting bandwidth. Up to 16 customers can be simultaneously connected with each having up to 1Gbps of dedicated, symmetrical bandwidth. This solution is designed to enable service providers to address multiple markets such as Fiber-To-The Building (FTTB FTTB Fiber To The Building FTTB Fiber To The Business (NEC) FTTB For The Time Being FTTB Fiber to the Block ) and Fiber-To-The-Curb (FTTC (Fiber To The Curb) The installation of optical fiber to within several hundred feet of the home or office. At that point, the optics are converted into electronics for delivery into the premises, typically using DSL. ) with a single product. Combined with the PONy Express, WDM-PON uses an Arrayed Waveguide Grating Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. These devices are capable of multiplexing a large number of wavelengths into a single optical fiber, thereby increasing the transmission capacity of (AWG (American Wiring Gauge) A U.S. measurement standard of the diameter of non-ferrous wire, which includes copper and aluminum. In general, the thicker the wire, the greater the current-carrying capacity and the longer the distance it can span. ) to multiplex and demultiplex wavelengths between the feeder fiber and the distribution fibers instead of a traditional Planar Lightwave Circuit (PLC) splitter. In a WDM-PON system that uses "colorless" optics, the AWG also is responsible for spectrally slicing a seed light, generally provided from the Optical Line Terminal (OLT), into the individual wavelengths that are passed to the Optical Network Terminals (ONTs). The AWG can be packaged in the same form factor as existing PLC splitters, enabling service providers to insert a module into an existing GPON fiber distribution cabinet to support WDM-PON. As a result, service providers can choose to offer residential services via GPON and commercial services via WDM-PON. As their residential customers demand more bandwidth, service providers can simply move the distribution fiber from the PLC splitter to the AWG and provide up to 1 Gbps without service disruption to the GPON network. Solution Benefits The PONy Express WDM-PON Solution combines the best elements of private, point-to-point networks, security and dedicated bandwidth, with the best elements of traditional PON. Benefits for the service provider include: * Reduced inventory costs by using "colorless" ONUs and OLT line cards; * Plug-and-play simplicity to reduce time-to-market and eliminate wavelength management issues; * Reuse of existing fiber distribution products to support the passive WDM-PON Plug-and-Play splitter module; * Service and bit rate upgrades without infrastructure changes; * Coexistence with GPON to deliver residential and business services from the same fiber distribution cabinet; and * Simplification of the upgrade path from GPON to higher bandwidth support for services such as IP HDTV (High Definition TV) A set of digital television (DTV) standards that offer the highest resolution and sharpest picture. Although some HDTV sets are available in standard (rather square) screen sizes, the overwhelming majority of sets are wide screen, which eliminates .
