Product Description
Product Introduction
Erbium doped active fibers are mainly used for erbium-doped lasers and amplifiers. By introducing a pump source to achieve positive feedback, laser oscillation is formed to amplify the output. Its main pump wavelengths include 1480nm and 980nm, achieving high energy conversion power with relatively low pump power, meeting the requirements of C-band and L-band optical amplification in communication applications. Bait doped fiber is widely used in high-capacity long-distance optical communication and fiber optic sensors, with low coupling loss and low noise level.
