7. Summary Equipment needed to complete this project: Under Sea: 64x1660SM (each equipped with 16xSTM-1 and 2xSTM-16) 8x1686WM (16 each) 1024 Optical S-1.1 modules. Landing Station: 64x1660SM (each equipped with 16xSTM-1 and 2xSTM-16) 8x1686WM (16 each) 1024 Optical S-1.1 modules. NMS (1x1353SH + 1x1354RM) based on HP server. Martina Franca, 14 Dec 2001, M. Bonori 7

8. 1660SM - Optical STM-1 module This Optical Module (S-1.1) will be used as Electrical/Optical converter within the customer equipment in both sides, under sea and in the landing station. Consume = 1,5 W One module for each floor of the tower. One module for each receiver in the landing station. Martina Franca, 14 Dec 2001, M. Bonori 8

9. 1660SM Each 1660SM will be equipped with 16 Optical STM-1 tributary to the tower that will be protected with EPS N+1 and 2 Optical STM-16 (Colored) interfaces to the DWDM systems for the SNCP protection. All common cards are protected EPS 1+1. Subrack Size= 482W x 250D x 650H mm Consume= 211W (if equipped with 16xSTM-1 + 2xSTM-16) Martina Franca, 14 Dec 2001, M. Bonori 9

10. 1686WM These equipment are used to concentrate 16xSTM-16 channel to one lambda. 4x1686WM are necessary to carry the main traffic and other four to carry the protection. A booster +14/+17dB will be necessary depending on the real length of the submarine cable. Subrack Size= 482W x 250D x 400H mm Consume= 90W (if equipped with 16 and a +14dB booster) Martina Franca, 14 Dec 2001, M. Bonori 10

11. 64 * Alcatel 1660 = 64 * 211 W = 13504 W 8 * Alcatel 1686 = 8 * 80 W = 640 W 4096 * S-1.1 = 4096 * 1.5 W = 6144 W Totale potenza in acqua = 20288 W Totale potenza a terra = 20288 W Martina Franca, 14 Dec 2001, M. Bonori 11 Bilancio della Potenza per il trasporto dati
