The US International Trade Commission initiated a 337 investigation and was applied for by a professor at Columbia University. The professor accused more than 30 companies worldwide, including Nokia and Motorola, from producing in the United States, and LED products sold to the United States infringed on a patent filed in the 1990s. Patent No.: 5252499, mainly related to the production method of short-wavelength light-emitting diodes.
People are accustomed to refer to short-wavelength light-emitting diodes as LEDs, which are regarded as an advanced next-generation light source because of their low energy consumption and high stability. They are widely used in various consumer electronic products and lighting devices. For example, the outdoor lighting of the Olympic Stadium Water Cube uses LED products. According to statistics, in 2007, China's LED exports to the US were about 350 million US dollars, up 53.9% year-on-year, and nearly 100 Chinese companies involved in LED exports to the US. Experts reminded that this must not be ignored.
National Semiconductor Lighting Engineering Development and Industry Alliance Zibo said: "We must not give up responding, because if you do not respond, ITC (United States International Trade Commission) general exclusion will be issued soon, should be a whole for our industry A major blow, and if lost, we will not only lose the US market, but in Europe and the rest of the world, we will have more losses. At the same time, our mid-stream and downstream products will have tens of billions of dollars in losses."
LC Patch Cord is a fiber optic cable used to attach one device to another for signal routing. LC stands for Lucent Connector. It is a small form-factor fiber optic connector, half the size of the SC. LC Fiber Patch Cord divides to Single Mode and Multi Mode Fiber Optic Patch Cord. According to the connector structure type, it divides FC, SC, ST, MU, D4, E2000, LC etc.. According to the polished ceramic end-face, it divides to PC, UPC and APC.Fiber Patch Cord such as Riser Jacket (OFNR), Plenum Jacket (OFNP), PVC Jacket, Low Smoke Zero Halogens (LSZH).The LC Fiber Patch Cable is available in both single mode and multimode versions, and is fully intermateable with fiber optic products. LC LC patch cord both single mode and multimode versions LC fiber patch come with a zirconia ceramic ferrule with pre-polished UPC profile and convex spherical end. These end face types allow for faster polishing, and low back reflection and optical loss, while ensuring maximum repeatability.
