It is commonly used when the received optical power is too strong for the optical receiver, or when engineers need to balance link budgets during installation, testing, and maintenance.<\/p>\n<p>This FC UPC Attenuator is suitable for telecom rooms, ODF systems, optical transceivers, media converters, switches, routers, servers, storage devices, fiber test equipment, and general single mode optical communication links.<\/p>\n<p>Compared with APC attenuators, FC\/UPC attenuators are better suited for general optical links, lab testing, data communication systems, transceiver testing, and equipment connections where UPC interfaces are already used. If your fiber equipment, patch cable, or adapter is FC\/UPC, this FC UPC Fixed Fiber Optic Attenuator is the correct matching connector type.<\/p>\n<p>Luleey provides multiple fixed attenuation values from 0dB to 30dB, helping installers and network engineers select the proper optical power reduction value for different fiber link requirements.<\/p>\n<h2>Recursos<\/h2>\n<ul>\n<li>FC UPC Fixed Fiber Optic Attenuator for single mode fiber networks<\/li>\n<li>Fixed attenuation values for stable optical power reduction<\/li>\n<li>FC\/UPC connector for general single mode optical links<\/li>\n<li>Available attenuation range from 0dB to 30dB fixed values<\/li>\n<li>Helps protect optical receivers from excessive input power<\/li>\n<li>Helps balance optical link budget in telecom, ODF, data communication, and fiber testing systems<\/li>\n<li>Suitable for optical transceiver testing and receiver power adjustment<\/li>\n<li>Low insertion loss and good repeatability<\/li>\n<li>Plug-and-play passive optical component<\/li>\n<li>Reusable design for installation, testing, and maintenance<\/li>\n<li>Suitable for switches, routers, media converters, optical transceivers, servers, fiber NICs, storage devices, and test tools<\/li>\n<li>Factory tested by Luleey for practical optical network deployment<\/li>\n<\/ul>\n<h2>Aplicativos<\/h2>\n<ul>\n<li>Telecom Room Fiber Links<\/li>\n<li>ODF Optical Distribution<\/li>\n<li>Optical Power Adjustment<\/li>\n<li>Fiber Link Budget Balancing<\/li>\n<li>Optical Receiver Protection<\/li>\n<li>Fiber Testing and Maintenance<\/li>\n<li>Optical Transceiver Testing<\/li>\n<li>Media Converter Deployment<\/li>\n<li>Switch and Router Fiber Links<\/li>\n<li>Server and Storage Fiber Connections<\/li>\n<li>Data Communication Systems<\/li>\n<li>Laboratory Optical Testing<\/li>\n<li>General Single Mode Fiber Networks<\/li>\n<\/ul>\n<h2>Especifica\u00e7\u00f5es<\/h2>\n<table>\n<thead>\n<tr>\n<th>Par\u00e2metro<\/th>\n<th>Valor<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Marca<\/td>\n<td>Luleey<\/td>\n<\/tr>\n<tr>\n<td>Tipo de produto<\/td>\n<td>FC UPC Fixed Fiber Optic Attenuator<\/td>\n<\/tr>\n<tr>\n<td>Tipo de conector<\/td>\n<td>FC\/UPC<\/td>\n<\/tr>\n<tr>\n<td>Tipo de atenuador<\/td>\n<td>Valor fixo<\/td>\n<\/tr>\n<tr>\n<td>Tipo de fibra<\/td>\n<td>Fibra monomodo<\/td>\n<\/tr>\n<tr>\n<td>Valores de atenua\u00e7\u00e3o dispon\u00edveis<\/td>\n<td>0 dB, 1 dB, 2 dB, 3 dB, 4 dB, 5 dB, 6 dB, 7 dB, 8 dB, 9 dB, 10 dB, 11 dB, 12 dB, 13 dB, 14 dB, 15 dB, 16 dB, 17 dB, 18 dB, 19 dB, 20 dB, 25 dB, 27 dB, 30 dB<\/td>\n<\/tr>\n<tr>\n<td>Faixa de atenua\u00e7\u00e3o<\/td>\n<td>Valores fixos de 0 dB a 30 dB<\/td>\n<\/tr>\n<tr>\n<td>Uso t\u00edpico<\/td>\n<td>Redu\u00e7\u00e3o da pot\u00eancia do sinal \u00f3ptico e ajuste do or\u00e7amento de enlace<\/td>\n<\/tr>\n<tr>\n<td>Perda de retorno<\/td>\n<td>Projeto com alta perda de retorno<\/td>\n<\/tr>\n<tr>\n<td>Perda de inser\u00e7\u00e3o<\/td>\n<td>Projeto com baixa perda de inser\u00e7\u00e3o<\/td>\n<\/tr>\n<tr>\n<td>Durabilidade do plug-in<\/td>\n<td>Mais de 1.000 vezes<\/td>\n<\/tr>\n<tr>\n<td>Equipamentos de aplica\u00e7\u00e3o<\/td>\n<td>Transceptores \u00f3pticos, switches, roteadores, conversores de m\u00eddia, servidores, placas de rede de fibra \u00f3ptica, dispositivos de armazenamento, equipamentos de teste \u00f3ptico<\/td>\n<\/tr>\n<tr>\n<td>Aplicativo de rede<\/td>\n<td>Telecom, ODF, optical distribution, data communication, fiber testing<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Why Use an FC UPC Fiber Optic Attenuator?<\/h2>\n<p>A fiber optic attenuator is used when the optical signal power is too high for the receiving device.
