DCM dispersion compensation device 1U RACK TYPE

Overview

Fiberroad Technology Co. optical compensation function with slope dispersion compensation for standard single-mode fiber can DCM (G.652) were dispersion and dispersion slope compensation broad band in the C-band, allowing the system to optimize residual dispersion. In the dispersion compensation value of 1545nm wavelength dispersion can reach -2070ps / nm.

The DCMs offer a high dispersion compensation level and a very low insertion loss penalty. They provide negative dispersion compensation over the full C-Band with possible distance extensions of up to 120 kilometers.

Highlights

DWDM system dispersion compensation and broadband low residual dispersion

G.652 fiber C-band 100% slope compensation (standard value)

Low insertion loss

Low polarization mode dispersion

Performance indicators by

Telcordia GR-2854-CORE standard certification

Reliability by Telcordia GR-1221-CORE standard certification

Dispersion compensation and dispersion slope compensation

Obtained at a specific wavelength dispersion compensation, should satisfy the following relationship:

DTF × LTF + DDCF × LDCF = 0

DTF: transmission fiber dispersion;

LTF: length of the transmission fiber;

DDCF: dispersion of the dispersion compensating optical fiber;

LDCF: dispersion compensation fiber length;

Dispersion slope compensation in the band, should satisfy the following relationship:

STF × LTF + SDCF × LDCF = 0

STF: dispersion of the transmission fiber;

SDCF: dispersion of the dispersion compensating optical fiber

According to the above two relationships obtained dispersion compensation and dispersion slope

compensation, should satisfy the following relation:

RDSDCF = SDCF / DDCF = STF / DTF

Assuming standard single mode fiber at 1545nm wavelength dispersion of 16.7ps / nm / km, a dispersion slope of 0.060 ps / nm² / km, RDS about 0.0036nm^﹣1
