    • L-Band Erbium Doped Fibers

    This L-band Erbium Doped Fiber (EDF) product offers a pioneering fiber design that provides superior performance for L-band Erbium Doped Fiber Amplifiers (EDFAs). The core composition of EDFL-1480-HP-30 has been engineered to maximise the gain performance between 1570nm to 1630 nm and beyond. This allows use of the fiber in L, L+, L++ and Super L-band amplifiers.Its high cut-off wavelength (HC) fibers have larger core diameters, reducing non-linear effects and increasing efficiency at higher pump powers.

    产品特点Highly consistent and reproducible spectroscopy — no need to batch matching GFFs、 Excellent core concentricity — low splice loss、 Detailed lot-specific characterization data — compatible with modeling programs
