Alcatel has introduced enhanced singlemode fiber (E-SMF), designed to reduce ongoing costs for network operators by adding about a third more wavelengths to the usable spectrum and extending transmission reach by 50 percent.
Alcatel's E-SMF advancements focus on reducing the fiber's attenuation, or signal loss. The maximum attenuation is decreased in the E frequency band (1350-1450 nm), which adds about 30 percent more wavelengths available for use on a single fiber, claim Alcatel representatives. Improvements have also been made to the fiber's polarization mode dispersion capabilities. The new fiber is compliant with the standards of ITU's G.652 table C.
