Adjustable optical attenuators are supplied by manufacturers

Leading manufacturers of adjustable optical attenuators include Viavi Solutions, DiCon Fiberoptics, Agiltron, Thorlabs, and EKSMA Optics, offering both manual and motorized variable attenuators for diverse applications.

Key Manufacturers and Offerings

Viavi Solutions, Inc. – Based in Arizona, USA, Viavi provides a full range of optical attenuators, including variable optical attenuators (VOAs) for field, lab, and manufacturing environments. Their products support singlemode and multimode fibers and are designed for installation, maintenance, and photonic-layer testing applications.

Di

Con Fiberoptics – Located in Richmond, California, DiCon manufactures fiber optic components including VOAs, optical switches, and passive components. Their variable attenuators are suitable for telecom, data center, and industrial applications, with options for precise power control. Agiltron – Agiltron offers high-performance optical and electro-optical products, including adjustable attenuators.

They provide both manual and motorized VOAs, serving sectors such as aerospace, defense, communications, and life sciences. Agiltron emphasizes precision, reliability, and ISO 9001-certified quality. Thorlabs – Thorlabs supplies a wide variety of VOAs for single mode (SM), polarization-maintaining (PM), and multimode (MM) fibers.

Their products include electronic VOAs with FC/PC or FC/APC connectors, as well as manual VOAs for lab and industrial use.

EKSM

A Optics – Specializes in variable attenuators for linearly polarized laser beams, including Nd-host lasers and femtosecond broadband applications. They offer both manual and motorized versions, highly customizable for laboratory and high-power laser applications.

Additional Considerations

Manual vs. Motorized: Motorized VOAs allow remote or automated control, ideal for high-power or precision applications, while manual VOAs are simpler and cost-effective for lab setups. Wavelength Range: Ensure the attenuator supports the specific wavelength of your laser or fiber-optic system.

Connector Types: Common connectors include FC/PC, FC/APC, LC, SC, and SMA, depending on fiber type and system requirements.

High-

Power Applications: Some manufacturers, like EKSMA Optics and LASEROPTIK, provide attenuators designed for high-power laser diagnostics and industrial use. These manufacturers represent a reliable starting point for sourcing adjustable optical attenuators for research, industrial, or telecom applications.
