The
TeraLight Non-Zero Dispersion Shifted Fiber (NZDSF) is uniquely optimized for
effective area, chromatic dispersion and dispersion slope. This enables
excellent distortion management, cost effective operation at 10 and 40Gbps,
tight channel spacing in C- and L-bands, compatibility with the future S-band.
TeraLight Ultra is optimized for long haul and ultra long haul applications.
Its reduced 1550nm chromatic dispersion (compared to standard SMF) results in
lower costs for dispersion compensation, still high enough to counter
cross-channel non-linearities. Channel spacing as low as 25GHz at 10Gbps in C-
and L-bands allows future capacity expansion. Commercially available dispersion
compensating devices provide near 100% chromatic dispersion and dispersion slope
compensation.
Low attenuation in the 1450nm region ensures maximum efficiency of distributed
Raman amplification systems. Guaranteed low PMD link design values keep
distortions within tolerable limits, permitting cost-effective longer
transmission distances without regeneration at 40Gbps.
The
fiber complies with or exceeds ITU-T G.655.E / G.656 and IEC 60793-2-50 type B4
/ B5. The fiber can be used in all cable constructions, including loose tube,
tight buffered, ribbon, and central tube designs.
Proprietary ColorLock®
coating process further enhances the performance, durability and reliability of
the fiber, even in the harshest environments.
