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 60km 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 40km, can I use 60km or 80km instead if I don’t have 40km 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.
Q: What is the lead time for SSN2DCU(60km/60km,LC) board?
A: In normal condition is 5 days, better to confirm with our sales team before your purchase.
