Description
The FC Single Mode Variable Attenuator is a precision component designed to manage optical signal power within fiber optic transmission systems. It allows attenuation adjustments from 1dB to 30dB, making it ideal for controlling the optical power received by photodetectors, preventing receiver overload and ensuring signal integrity.
Constructed with a nickel-plated brass housing, this variable attenuator offers high durability and stability, capable of withstanding high-power light sources. It is compatible with standard FC connectors, featuring a male-to-female interface that simplifies installation into existing fiber networks. This attenuator is widely used in telecommunications, FTTx deployments, LAN, and CATV networks, as well as in testing instruments where precise optical power control is required. FiberMania offers customization options to meet specific OEM/ODM project requirements.
