C20 2010-01-29 Page 1 of 1 C20: Properties of cabled TeraLight® NZDS optical fibre For high bit rate DWDM systems in the long-haul and Metro environment To minimize your chromatic dispersion compensation CAPEX General and application Teralight® Non-Zero Dispersion Shifted Fibre (NZDSF) has set the standard for high bit-rate, multi-wavelength transmission. Its unique optimization of effective area, chromatic dispersion and dispersion slope enables excellent distortion management, cost-effective operation at 10 and 40 Gbps, tight channel spacing in C and L bands, compatibility with future S band and provides full compliance with the new ITU G.656 recommendation. TeraLigth® is further optimized for long-haul applications. It supports 10 Gbps transmission without dispersion compensation for distances of about 200 km, resulting in cost savings compared to standard single mode fibre. For longer distances or 40 Gpbs operation, commercially available compensating devices can be used. The same fibre also supports short-length metro systems, providing additional cost savings.
