Overview
The MU Attenuator is a high-precision optical component designed for singlemode fiber networks. It features a male-to-female configuration, allowing for quick integration into existing fiber links to reduce signal strength to desired levels without disrupting network topology.
Constructed with doped fiber technology, this attenuator provides stable and consistent attenuation across both 1310nm and 1550nm operating wavelengths. It is ideal for data center, telecommunications, and enterprise network environments where signal power management is necessary to prevent receiver saturation.

Frequently Asked Questions
What is the purpose of this attenuator?
It is used to reduce the signal strength of a fiber optic line, which is often required to prevent signal overload at the receiver end.
Can this be used on multimode fiber?
No, this model is designed specifically for singlemode fiber applications.
Is the attenuation value adjustable?
No, this is a fixed attenuator with a set value of 2dB.
What wavelengths does this support?
It is optimized for use at standard 1310nm and 1550nm operating wavelengths.
How does it connect to my equipment?
The male-to-female configuration allows you to plug the male side into a port and the female side to receive another patch cable.
