Er40-4/125

Liekki Er40-4/125 is a highly doped fiber for L-band amplifiers requiring very low level of PMD and non-linear effects. This fiber is available as a low cutoff and a high cutoff version. The typical fiber

length per application is about 15m.

Optical Characteristics:

■ Peak absorption at 1530nm: 40 ± 4dB/m

■ Mode field diameter at 1550 nm: 6.5 ± 0.5|im

■ Core numerical aperture: 0.2 ± 0.02

■ Fiber cutoff wavelength: 1000-l400nm

Er80-8/125

Liekki Er80-8/125 is a large-mode-area single-mode fiber suitable for high-power amplifiers and lasers (output power of 25dBm or more). Good spliceability, high doping and large core make this

fiber ideal for high-peak-power pulse amplification in the eye-safe

Ujim wavelength region.

Optical Characteristics:

■ Peak absorption at 1530 nm: 80 ± 8dB/m

■ Mode field diameter at 1550 nm: 9.5 ± 0.5|im

■ Core numerical aperture: 0.13 ± 0.02

■ Fiber cutoff wavelength: 1100-1400nm

■ Mode field diameter at 1550 nm: 6.5 ± 0.5|im

■ Core numerical aperture: 0.2 ± 0.02

■ Fiber cutoff wavelength: 800-980nm

Er11

Er110-4/125

Liekki Er110-4/125 is a highly doped fiber for ultra-short pulse amplifiers operating in the 1.5|im wavelength region. Very high erbium concentration minimizes required application fiber length

while providing strong gain and reduced non -linear effects.
