Erbium-doped Fiber for Optical Amplifier

Categories ,
Inquiry

This series of erbium-doped fiber can meet the most demanding optical amplifier design requirements. The amplification range covers the C-band and L-band. Using 1480nm or 980nm pumping technology, erbium-doped fibers can achieve an amplification bandwidth of 35nm. And keep the gain flat within the bandwidth, and obtain ideal power conversion efficiency. YOFC’s erbium-doped fibers are designed for fiber amplifiers with high performance and low noise indicators. For example: optical preamplifiers, optical power amplifiers and online amplifiers in WDM communication systems. Erbium-doped fiber products use erbium-aluminum co-doping design to ensure high-quality performance.
