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 SC UPC Attenuator is suitable for FTTH, FTTX, CATV, telecom rooms, ODF systems, PON networks, fiber testing, optical transceivers, media converters, switches, routers, servers, storage devices, and optical network maintenance.<\/p>\n<p>The SC\/UPC connector uses an angled polish structure, making it suitable for low-reflection single mode optical systems. Compared with UPC connectors, UPC connectors are more commonly used in FTTH, CATV, PON, and optical distribution environments where return loss performance is important.<\/p>\n<p>Luleey provides multiple fixed attenuation values from 0dB to 30dB, helping installers and network engineers select the proper signal reduction value for different optical link requirements.<\/p>\n<h2>Recursos<\/h2>\n<ul>\n<li>SC UPC Fixed Fiber Optic Attenuator for single mode fiber networks<\/li>\n<li>Fixed attenuation values for stable optical power reduction<\/li>\n<li>SC\/UPC connector for low-reflection 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 FTTH, CATV, telecom, and PON networks<\/li>\n<li>Suitable for 1310nm and 1550nm single mode applications<\/li>\n<li>High return loss design for stable optical performance<\/li>\n<li>Low insertion loss and good repeatability<\/li>\n<li>Good wear resistance for repeated connection<\/li>\n<li>Plug-and-play passive optical component<\/li>\n<li>Suitable for fiber switches, routers, media converters, optical transceivers, servers, fiber NICs, storage devices, and test equipment<\/li>\n<li>Useful for optical network deployment, troubleshooting, maintenance, and lab testing<\/li>\n<\/ul>\n<h2>Aplicativos<\/h2>\n<ul>\n<li>FTTH Fiber Networks<\/li>\n<li>FTTX Access Networks<\/li>\n<li>CATV Optical Systems<\/li>\n<li>PON Optical Networks<\/li>\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>Laboratory Optical Testing<\/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>SC UPC Fixed Fiber Optic Attenuator<\/td>\n<\/tr>\n<tr>\n<td>Tipo de conector<\/td>\n<td>SC\/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>Comprimento de onda de trabalho<\/td>\n<td>1310nm \/ 1550nm<\/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>Perda de retorno<\/td>\n<td>\u226550dB<\/td>\n<\/tr>\n<tr>\n<td>Tempos de reutiliza\u00e7\u00e3o<\/td>\n<td>Mais de 1.000 vezes<\/td>\n<\/tr>\n<tr>\n<td>Temperatura de trabalho<\/td>\n<td>-40 \u00b0C a +85 \u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Temperatura de armazenamento<\/td>\n<td>-55\u00b0C to +85\u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Material do n\u00facleo<\/td>\n<td>Ceramic<\/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>Aplicativo de rede<\/td>\n<td>FTTH, FTTX, CATV, PON, telecom, optical distribution, fiber testing<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Why Use an SC 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.
