Fiber and communications infrastructure knowledge brief Published 21 Dec 2024

Prepared for preliminary research by the METRA knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Top manufacturers for multimode fiber optic attenuators include FS, Fibertronics, Thorlabs, and DigiKey, offering both fixed and variable solutions for 50/125 µm and 62. 5/125 µm fibers. Leading Manufacturers and SuppliersFS (Fiberstore) offers a wide range of fixed and variable fiber optic attenuators with stable attenuation from 0 to 60 dB, suitable for WDM transmission and multimode fiber applications.

Their products are known for consistent performance and compatibility with various connector types. Fibertronics, Inc. provides an extensive selection of multimode attenuators for 50/125 µm and 62. 5/125 µm fibers.

They offer male-to-female buildout pads, in-line attenuators, and adjustable air-gap attenuators with connectors including LC, SC, FC, and ST. Custom lengths and connector types are available to match specific system requirements. Thorlabs specializes in variable multimode fiber optic attenuators (VOAs), which allow precise adjustment of optical power by controlling the air gap between connectors.

Their products support FC/PC and SMA connectors and are ideal for lab instrumentation, optical spectrum analyzers, and detector protection.

Digi

Key serves as a distributor for multiple manufacturers, offering a large in-stock selection of multimode fiber optic attenuators with various connector types (D4/PC, FC, SC, ST, MU) and fixed or dual-window attenuation options. This makes it convenient for rapid procurement and same-day shipping.

Selection Considerations

When choosing a multimode fiber attenuator, consider: Fiber type and core size: 50/125 µm or 62. 5/125 µmConnector compatibility: LC, SC, FC, ST, SMA, etc. Attenuation type: fixed vs variable (air-gap or in-line)Application: lab testing, WDM power balancing, or receiver protectionCustomization needs: length, connector type, or specific insertion lossThese manufacturers and distributors provide reliable options for both commercial and laboratory applications, ensuring compatibility with multimode fiber systems and precise optical power control.
