Novel network fiber to manage dispersion at 1.55 /spl mu/m with combination of 1.3 /spl mu/m zero dispersion single mode fiber

New type of network fiber which has reverse dispersion and dispersion slope against 1.3 /spl mu/m zero dispersion SMF was designed and fabricated. The total dispersion was managed to be nearly zero and flat at 1.55 /spl mu/m region by combining SMF with new fiber of approximately 1:1 length.
