Description

Supports the compensated dispersion of 1360 ps/nm (for the dispersion caused by the 80 km G.652 optical fiber).

Compensates for the dispersion accumulated during the transmission by using the chirp grating and suppresses the pulse signals to restore the optical signals.

Realizes long haul transmission with optical regeneration when working with the BA and PA.

 

SSN1DCU02 is a dispersion compensation board for Huawei OSN3500, OSN7500, provide equally 80km compensate for the dispersion after long haul transmission for 10G signal system. The SSN1DCU02 part number is 03027541.

Q: What the last two number mean of SSN1DCU02?

A: The last two digital number means the DCU feature code, the relation as below:

Board Feature Code Output Optical Powe
SSN1DCU01 01 Compensated dispersion for a single channel: 60 km
SSN1DCU02 02 Compensated dispersion for a single channel: 80 km
SSN1DCU03 03 Compensated dispersion for dual channels: 60 km/60 km
SSN1DCU04 04 Compensated dispersion for dual channels: 80 km/80 km
SSN1DCU05 05 Compensated dispersion for dual channels: 60 km/80 km

SSN2DCU08 08 Compensated dispersion for dual channels: 40 km/80 km
SSN2DCU09 09 Compensated dispersion for dual channels: 60 km/80 km

 

Q: Can I use it to compensate STM-16 signal?

A: No, it working bit rate is 10G, only for STM-64 signal.

 

Q: Can I use two 40km compensation card to replace one 80km compensation condition?

A: Yes, but please consider the insert loss of DCU board, if your optical power is not enough. More technical assistance, you can contact with supports@thunder-link.com.

 

Q: My compensation required is 80km, can I use 40km or 60km instead if I don’t have 80km board?

A: 40km is recommended, principle is less compensation, not over compensation.

 

Q: Can I return/exchange board if not compatible with my system?

A: Yes, please tell our sales team your system and main control board version, before your purchase.

 

Q: The board is new or refurbished?

A: Yes, it is original new, not been used.
