LC\/UPC Fiber Optic Attenuator for 5dB Singlemode Power Reduction<\/h2>\n

This LC\/UPC Fiber Optic Attenuator provides a fixed nominal 5 dB reduction in optical signal power. Its male-to-female LC\/UPC configuration fits a compatible singlemode connection where received optical power needs to be reduced without changing the connector interface.<\/p>\n

Designed as a compact plug-in attenuator, it can be positioned between a compatible LC\/UPC connector and an LC\/UPC adapter in a distribution panel, cabinet, or test setup. The blue housing has a visible 5dB marking for identification. Match both connector polish and the required attenuation to the link before installation.<\/p>\n

The supplier lists 1310 nm and 1550 nm as singlemode reference wavelengths, return loss of at least 50 dB, and a 500-cycle mating specification. Select this fixed value only after checking the optical power budget; 5 dB is not a universal setting for every fiber link.<\/p>\n

Fixed Fiber Optic Attenuators: Selection and Applications<\/h3>\n

A fixed fiber optic attenuator reduces optical signal power by a specified amount. It is used when a receiver would otherwise see excessive optical power, or when a test or distribution link calls for controlled attenuation. Select the attenuation value from the actual optical link budget rather than connector color alone.<\/p>\n

\"Fixed<\/p>\n

Fixed attenuators are available in different connector families, polish types and nominal dB values. Choose a model that matches the fiber mode, connector interface, and endface polish of the intended connection. The illustration uses a 5 dB LC-style unit as an example; other interface and attenuation options require their own matching product specifications.<\/p>\n<\/div>\n
