Proximion Claims Industry's Fastest Scan Time for Optical Performance Monitoring.Business Editors Optical Fiber Communications 2002 ANAHEIM, Calif.--(BUSINESS WIRE)--March 18, 2002 Proximion Fiber Optics fiber optics, transmission of digitized messages or information by light pulses along hair-thin glass fibers. Each fiber is surrounded by a cladding having a high index of refractance so that the light is internally reflected and travels the length of the fiber AB, a supplier of Optical Layer Monitoring(TM) for safeguarding and enhancing the performance of optical networks, disclosed a record-breaking scan time for its optical layer monitor, WISTOM(R). WISTOM is the only subsystem that scans the whole C-band in 0.1 milliseconds and reports channel specific problems with a response time of less than 10 milliseconds, while simultaneously measuring wavelength, power, and Optical Signal/Noise Ratio (OSNR OSNR Optical Signal Noise Ratio OSNR Optical Signal to Noise Ratio ). By quickly identifying network faults and initiating protection methods to preserve critical data, operators minimize network downtime and associated operational costs using WISTOM. By leveraging fiber Bragg gratings A short length of optical fiber that filters out a particular wavelength. Periodically spaced zones in the fiber core are altered to have different refractive indexes slightly higher than the core. and the patented ability to embed functionality directly into the fiber layer, WISTOM combines performance and speed into one single, versatile product. Until now, system vendors needed to buy two separate units focused on either speed or accuracy, one for optical performance monitoring Optical performance monitoring (OPM) is used for managing high capacity dense wavelength division multiplexing (DWDM) optical transmission and switching systems in Next Generation Networks (NGN). and another for channel monitoring, which leads to increased operational cost. By opening up a very narrow transmission window of an otherwise very broadband, highly reflective fiber Bragg grating, Proximion's scanning filter makes it possible to provide both high detail and unprecedented scanning speed without using any moving parts Moving parts are the components of a device that undergo continuous or frequent motion, most commonly rotation. "Parts" only include the mechanical components which does not include fuel, or any other gas or liquid. . WISTOM's high-performance filter continuously scans the optical network layer at over 300 million bits per second (or 8 times faster than the super sonic speed of an F16 fighter jet), making it possible to perform protection switching in under 10 milliseconds, while generating a precise depiction of the optical layer in the form of a data stream. Proximion's real-time hardware and software platform then retrieves and processes the data stream on the fly, providing instantaneous monitoring of all necessary optical performance parameters. Thus, two parallel and independent processes provide simultaneous optical performance and channel monitoring. WISTOM analyzes the performance of each individual wavelength channel and pinpoints the problem to be resolved, ensuring Quality of Service (QoS) for network operators. Due to its fast scan time and high-performance, WISTOM provides a complete platform that can be used for many applications including protection switching, fast dynamic gain equalization In communications, techniques used to reduce distortion and compensate for signal loss (attenuation) over long distances. and long-term drift monitoring. As a highly modular platform, WISTOM fits in all networks and can easily accommodate future features and applications. About Proximion Proximion Fiber Optics is a supplier of Optical Layer Monitoring(TM) for safeguarding and enhancing the performance of optical networks. Based on advanced fiber Bragg gratings, Proximion's groundbreaking In-Fiber Intelligence embeds functionality into the fiber layer to detect and counteract network faults. By offering full visibility of critical optical parameters, Proximion's product enables system vendors and carriers to prove and maintain Quality of Service (QoS) in DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM. DWDM - wavelength division multiplexing networks. Proximion was founded in 1998 and is a privately held company privately held company A firm whose shares are held within a relatively small circle of owners and are not traded publicly. headquartered in Kista, Sweden, with a presence in the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America.
