Dispersion Compensating Fiber
Advanced dispersion compensating module (ADCM) can compensate the dispersion and dispersion slope at C-band for standard single-mode fiber(G.652) and the system residual dispersion is optimized.
Dispersion values varying from -10 to -2100 ps/nm at 1550nm wavelength. Other center wavelength and dispersion values are available as requested.
Applications:
Long-haul telecommunication systems with standard single-mode fiber (G.652)
DWDM transmission systems
SDH transmission system
Dispersion adjusting
Features:
Slope compensation of G.652 fiber in C-band (Typical)
Features Telcordia GR-2854-CORE qualified
Reliability Telcordia GR-1221-CORE qualified
Different package styles, connector types and pigtail lengths available

Optical Parameters
Note:
(1) Insertion Loss is the maximum loss over operating wavelength range (1525nm-1565nm)
(2) PMD is average Differential Group Delay over the wavelength range measured by Jones Matrix Method.
(3) Other fiber length compensated is available.
