ANAHEIM, Calif. -- OFC 2002 -- Proximion Fiber Optics AB, a supplier of In-Fiber-Intelligence® for safeguarding and enhancing the performance of optical networks, has revealed the underlying technology behind WISTOM®, an ultra-fast, high-performance optical spectrum analyzer for DWDM networks. Proximion’s new white paper explains the technology behind WISTOM and how a fast scanning filter and advanced fiber Bragg gratings are combined into an optical layer monitor that, within milliseconds, detects and counteracts faults in DWDM networks. The paper also discusses the technology behind Proximion’s In-Fiber Intelligence; how optical communications monitoring can be done directly in the core of the fiber itself in order to avoid the disruption of network traffic and optical-electrical-optical conversions – taking a giant leap toward all-optical networks. The patented technology features Proximion’s unique approach to writing fiber Bragg gratings and dissects the basic elements of optical layer monitoringä. These findings highlight how an optical layer monitor can be used for numerous applications including protection switching, fast dynamic gain equalization and long-term drift monitoring to ultimately secure the optical communication layer by validating Quality of Service. In a separate release:Proximion Fiber Optics AB, a supplier of In-Fiber Intelligence® that safeguards and enhances the performance of optical networks, disclosed a record-breaking scan time for its optical layer monitor, WISTOM®. 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). 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 and the patented ability to embed functionality directly into the fiber layer, WISTOM combines performance and speed into one single, versatile Optical Layer Monitor. Until now, system vendors needed to buy two separate units focused on either speed or accuracy, one for optical performance monitoring 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.
