Manufacturer of Erbium-Doped Fiber Amplifiers DML
Key manufacturers of Erbium-Doped Fiber Amplifiers (EDFAs) include Thorlabs, Agiltron, Keopsys, and Fibotec, offering a range of benchtop, OEM, and rack-mounted solutions.
Thorlabs
Thorlabs provides core-pumped EDFAs with high small-signal gains and output powers in compact benchtop or PXIe module formats. Their EDFA100 and EDFA300 series deliver output powers of >20 dBm and >24.5 dBm, respectively, with low dispersion (<0.06 ps/nm) suitable for femtosecond pulse amplification. They offer single-mode (SM) and polarization-maintaining (PM) models, with built-in input and output isolators. Thorlabs also provides gain-flattening filters for applications requiring uniform spectral gain .
Agiltron
Agiltron specializes in high-quality EDFAs with cost-effective volume production. Their products are available as OEM modules, benchtop units, and network-ready rack-mount formats, designed for long operational lifespans exceeding 10 years. Agiltron emphasizes advanced thermal management, premium components, and rigorous testing to ensure durability, reliability, and efficiency .
Keopsys
Keopsys (part of Lumibird) offers a wide range of continuous-wave (CW) EDFAs with patented technologies to improve pumping efficiency, reduce power consumption, and extend lifetime. Their amplifiers cover C-band to L-band and are available in compact OEM modules or standalone plug-and-play units. Multiple interfaces such as RS232, RJ45, and USB are supported, and each unit comes with a test report verifying technical specifications .
Fibotec
Fibotec provides EDFAs that amplify light in the C- and L-band using erbium-doped fibers pumped at 980 nm or 1480 nm. Their products are applied in fiber-optic links, test and measurement setups, and free-space optical systems. Fibotec emphasizes customized solutions for specific optical applications, ensuring stable gain and minimal interchannel crosstalk .
Summary
These manufacturers offer a variety of EDFA solutions suitable for DML applications, including high-gain, low-noise, and polarization-maintaining options. Depending on your requirements—such as output power, form factor, or spectral range—you can select from Thorlabs for benchtop and PXIe modules, Agiltron for long-lifespan OEM and rack-mounted units, Keopsys for CW high-efficiency amplifiers, and Fibotec for customized fiber-optic solutions.
