2um-Band Dispersion-Compensating Fiber for Pulsed Applications (SM2000D PM2000D)

2um-Band Dispersion-Compensating Fiber for Pulsed Applications (SM2000D PM2000D)

Supplier
Shconnet
Part Number
SM2000D
Category
Optical Fibers
Origin
China

Coherent/Nufern’s single-mode SM2000D and polarization-maintaining PM2000D fibers are designed for dispersion compensation in the 2um band. Both the core-glass composition, a major factor in material dispersion, and the waveguide design, a major factor in waveguide dispersion, are optimized to give negative dispersion around 2um. SM2000D and PM2000D have approximately 2um core diameter, approximately 0.4 numerical aperture and a 4um mode-field diameter (MFD) at 2um. Their 125um cladding diameter provides good compatibility with active and passive fibers used in preamplifier stages and allows processing with conventional cleaving and splicing equipment. These dispersion-optimized fibers are particularly suitable for pulsed fiber lasers and fiber amplifiers in the 2um band.
