L-Band Erbium Doped Fibers
Fibercore’s L-band Erbium Doped Fiber (EDF) product, L-35(1530/125)HC, offers a pioneering fiber design that provides superior performance for L-band Erbium Doped Fiber Amplifiers (EDFAs).
The core composition of L-35(1530/125)HC 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. Fibercore’s high cut-off wavelength (HC) fibers have larger core diameters, reducing non-linear effects and increasing efficiency at higher pump powers.
Typical Applications:
• L-band EDFAs / Telecoms
• Low Power Fiber lasers
• Wide band ASE sources
• Lidar
