LC/UPC Fiber Optic Attenuator for 5dB Singlemode Power Reduction

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.

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.

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.

Fixed Fiber Optic Attenuators: Selection and Applications

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.

Fixed fiber optic attenuator application guide covering purpose, structure, typical uses, and common options

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.

FAQ

What does a fixed 5 dB fiber optic attenuator do?

It reduces optical signal power by a nominal 5 dB. It is used when the optical power budget calls for less power at a receiver or test point.

Can this LC/UPC attenuator be used with LC/APC connectors?

No. This model uses LC/UPC interfaces. Match the polish type at both mating ends; a system using LC/APC connections requires a suitable APC-compatible attenuator.

Where should the male-to-female attenuator be installed?

It is a plug-in component for a compatible LC/UPC singlemode connection, typically at an adapter or patch-panel port. Check the connector orientation and link power budget before fitting it.

Is the 5 dB model suitable for multimode fiber?

This offered configuration is specified for singlemode fiber. For a multimode link, select an attenuator specifically rated for the relevant multimode system.

How do I decide whether 5 dB is the correct attenuation?

Compare the measured or calculated receive power with the receiver’s allowed input range, then choose the attenuation needed for that link. The supplier lists 1310 nm and 1550 nm as reference wavelengths for this singlemode model.
