Description
i-Labs’ DCF4 Non-Zero Dispersion-Shifted Fiber (NZ-DSF) is designed to operate over the entire
C-band. Because of its low dispersion, short-to-medium lengths of DCF4 fiber minimize the dispersion
added to the system. For low-dispersion systems, the dispersion from DCF4 can be compensated using
short lengths of other fibers that have positive dispersion, such as SMF-28 Ultra. Additionally, DCF4
fiber has a large effective area that allows the fiber to carry high optical power without significant
non-linear effects.
