Lynx PLC-Based Photonic Switch Surpasses Industry Standards in Enhanced Durability Testing.Business Editors/High-Tech Writers CALABASAS HILLS, Calif.--(BUSINESS WIRE)--Dec. 2, 2003 8 Paths Concurrently Switch More Than 2 Billion Times with No Performance Degradation - 1,000x Telcordia Requirements An 8x8 photonic switch See optical switch. from Lynx Photonic Networks (www.LynxPN.com) has passed one of the most stringent tests in the optical communications Optical communications The transmission of speech, data, video, and other information by means of the visible and the infrared portion of the electromagnetic spectrum. industry to validate its endurance after repeated switching operations. Deploying Lynx's patented planar lightwave circuit (PLC) switching and light management technology, the device under test (a Photon.8x8 PCSS PCSS Pennsylvania Council for the Social Studies PCSS Photoconductive Semiconductor Switch PCSS Porter Creek Secondary School PCSS Process Control Simulation System PCSS Process Control Safety System PCSS Platform Check Sub-System (TM)) was subjected to two billion switching operations on eight paths, 1,000 times more switching operations than the two million required by the Telcordia standard GR-1073-CORE. In the fully documented test, each switching operation in all eight paths was monitored and verified by a dedicated photodiode A light sensor (photodetector) that allows current to flow in one direction from one side to the other when it absorbs photons (light). The more light, the more the current. Used to detect light pulses in optical fibers and other light-sensitive applications, it works the opposite of a three milliseconds after switching occurred, in order to verify the switching operation. After every two million switching operations, optical measurements of insertion loss The amount of loss attributed to a particular device being used in (inserted into) the system. For example, a circuit added to filter out unwanted frequencies may reduce the output current by some amount. See injection loss. (IL) and extinction ratio In telecommunications, extinction ratio ( r e ) is the ratio of two optical power levels, of a digital signal generated by an optical source, e.g., a laser diode, where P 1 (ER) were recorded. Throughout the two billion cycles, there was no recorded change in IL and ER measurements outside of the statistical measurement margin of error variances specified by the manufacturers of the test instruments. The test results confirm that Lynx's PLC silica-on-silicon technology - materials, processes and designs - is highly durable and withstands an extreme number of switching operations without any physical damage or performance degradation. "From a reliability standpoint, a switching cycle of two billion operations is three orders of magnitude beyond that required for Telcordia conformance," said Michael Leigh Michael Leigh is an artist, based in Cheshire, England and working mainly in the area of mail art. As well as working in his own name, he has produced work since 1980 as A1 Waste Paper Co. , Lynx president and co-founder. "And it is far superior to the performance of opto-mechanical switches, or other switches that contain 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. . Only Lynx's PLC switches have proven their extreme performance capability for carrier-class in-service operation." The ultra-reliable Photon.8x8 PCSS (Photonic Communications Switching Subsystem) has no moving parts and is the heart of several models in Lynx's new plug-and-play LightLEADER(TM) 3000 Series switch systems, including the LightLEADER 3424, which is designed for in-service applications such as ROADM ROADM Reconfigurable Optical Add/Drop Multiplexer ROADM Reconfigurable Add Drop Multiplexing (reconfigurable optical add/drop multiplexer A device installed at an intermediate point on a transmission line that enables new signals to come in and existing signals to go out. In a typical example, most signals pass through the device, but some would be "dropped" by splitting them from the line. ) or OXC See optical cross-connect. (optical cross-connect). Other LightLEADER models based on Lynx's PLC switches are aimed at various protection switch applications, optical test access and monitoring. "Carriers and their optical transport infrastructure vendors need to understand that not all transparent optical switches are created equal and that there are significant and often costly differences in implementation technology, scalability, reliability and robustness," said Frank Dzubeck, president of Communications Network Architects Inc., a Washington-based consulting firm. "In this new millennium, with ever increasing customer bandwidth demands, when it comes to reconfigurable optical add/drop multiplexers and protection switch applications, carriers cannot afford to make a mistake in their choice of technology or vendor." A report that includes a complete description of the test results is available under non-disclosure to Lynx's customers.
