SSN2DCU,Huawei OptiX OSN 3500 Dispersion Compensation Boards

Huawei OptiX OSN 3500 Dispersion Compensation Boards SSN2DCU Overview

DCU (dispersion compensation board).

The DCU is available in the following functional versions: N1 and N2. The difference between the two versions is with regard to the insertion attenuation and compensation.

The DCU is a dispersion compensation board. The DCU compensates for the dispersion that is accumulated in the fiber during the transmission of the optical signals in the 10 Gbit/s system, and compresses optical signal pulse. In this manner, the optical signals that are transmitted can be restored. In addition, the DCU can realize long-haul optical transmission when it works with an optical amplifier board.

The DCU can compensate for the dispersion for a maximum of two channels of optical signals. The DCU can be used with the BA and PA.

The DCU consists of the dispersion compensation module.

The front panel of the DCU has interfaces, and a laser safety class label.

The slots valid for the DCU vary with the cross-connect capacity and subrack of the OptiX OSN equipment.

Functions and features of the SSN2DCU

Function and Feature	N1DCU	N2DCU
Basic functions	Compensates for the dispersion of a maximum of two channels of optical signals at the same time. Supports the compensated dispersion of 1020 ps/nm (for the dispersion caused by the 60 km G.652 optical fiber), 1360 ps/nm (for the dispersion caused by the 80 km G.652 optical fiber), or any combination.	Compensates for the dispersion of a maximum of two channels of optical signals at the same time. Supports the compensated dispersion of 680 ps/nm (for the dispersion caused by the 40 km G.652 optical fiber), 1020 ps/nm (for the dispersion caused by the 60 km G.652 optical fiber), 1360 ps/nm (for the dispersion caused by the 80 km G.652 optical fiber), or any combination.
Dispersion compensation method	Compensates for the dispersion accumulated during the transmission by using the chirp grating and suppresses the pulse signals to restore the optical signals.
Long haul transmission with optical regeneration	Realizes long haul transmission with optical regeneration when working with the BA and PA.
Maintenance feature	Hot board swapping.
