Overview
The FC/UPC Male-Female buildout attenuator is a precision passive device designed to reduce the power level of optical signals in singlemode fiber optic networks. By providing a fixed, stable signal reduction, this attenuator prevents signal saturation in sensitive receivers and ensures optimal performance in telecommunications, data centers, and cable television headend environments.
Engineered for versatility, this attenuator utilizes doped fiber technology to maintain consistent attenuation across both the 1310nm and 1550nm operating windows. Its male-to-female (plug-and-jack) design allows for simple, direct installation between existing fiber patch cables and equipment ports or adapter interfaces, facilitating rapid integration without requiring specialized tools or additional splicing.

Frequently Asked Questions
Is this attenuator compatible with both 1310nm and 1550nm systems?
Yes, this device is designed to be suitable for operation in both 1310nm and 1550nm singlemode windows.
What does the Male-to-Female configuration mean?
The attenuator acts as an extension, where one side (male) plugs into an existing adapter or port, and the other side (female) accepts a standard fiber connector patch cord.
Are other attenuation values available?
Yes, fixed attenuation values can be provided in 1dB increments ranging from 1dB to 20dB.
What polish type is used on this connector?
This model uses a UPC (Ultra Physical Contact) polish.
Can I use this for multimode fiber applications?
No, this product is specified for use with singlemode fiber only.
