FS-DCM-90 Dispersion Compensation Module
The Fiberinthebox Dispersion Compensation Module (FSDCM) provides negative dispersion for dense wavelength division multiplexing (DWDM) transmission systems and can be used to compensate dispersion on standard single-mode optical fiber (SMF) across the entire C-Band. The small form factor (SFF) of the FSDCM enables extended DWDM transmission in a very small footprint. When combined with Fiberinthebox transponders and amplifiers, the WRDCM provides a simple, reliable, and cost-effective DWDM transpo solution.

The FSDCM-20, -30, and -40 are specifically targeted for link pre-compensation and may be used before a booster amplifier. The FSDCM-20, -30, -40, -50, and -60 may be used for inline compensation or for post-preamp applications. The WRDCM can suppo single- or multi-channel (C-Band) applications at both 2.5 and 10 G line rates.

FS DCM can compensate the dispersion with optimized residual dispersion for standard single-mode fiber (G.652) in the C-band.The modules based on mature and reliable optical fiber technology with excellent performance for optical transmission system. DCM modules are available with any dispersion values from -10 to -2100 ps/nm at 1550nm wavelength. We Fiberinthebox stock a diverse selection of DCM, range from 10KM to 120KM.
Key Features
100% slope compensation of G.652 fiber in C-band (Typical) Low Polarization Mode Dispersion Compensates standard single-mode optical fiber (G.652) Compatible with C-Band DWDM optical channels Low end-to-end inse ion lossVariety of compensation lengths19-inch 1RU rack mountable design
Applications
Provides dispersion compensation for extended reach applications Provides pre- and post-compensation Provides single- or multi-channel dispersion compensation
Typical Application Cases of FS-DCM Series
Compensated for the signal loss from DCF(dispersion compensating fiber) with amplifiers(a 5-km DCF may cause 2.5-dB losses.)


Dispersion compensating modules (DCM) have been engineered that are used in systems and/or in regenerators to help increase the span of fiber.


Optical add-drop multiplexers (OADM) may limit the dispersion. The reason is that the dispersion characteristics of a dropped signal and an added are not the same. This picture illustrates the point for the best and worst cases.
