MetroCor is a non-zero dispersion shifted fiber optimized for use in high-data-rate wavelength division multiplexed (WDM) systems, MetroCor fiber operates in the erbium-doped fiber amplifier (EDFA) window. Its low negative dispersion substantially decreases operating costs of optical networks. Typically deployed in metropolitan ring networks, MetroCor fiber's low negative dispersion extends ring distances by allowing optical signals to travel farther without dispersion compensation. MetroCor Fiber supports both 2.5 Gbps and 10 Gbps transmission, and its low dispersion in the C-band and L-band enables dense WDM deployment. MetroCor fiber enables the use of low-cost directly modulated distributed feedback (DM-DFB) lasers, which tend to have a high positive chirp. MetroCor increases the usable distance of DM-DFB lasers by providing compression of the pulse due to its negative dispersion characteristics, without the need for expensive dispersion compensation modules (DCMs). Corning MetroCor is in the G.655 / G.655- family of fibers along with other popular fibers such as the Alcatel 6911 Teralight Metro and Pirelli Widelight.
