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.

1660SM - Optical
STM-1 module
8
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.
One module for each
floor of the tower.
Consume = 1,5 W
Martina Franca, 14 Dec 2001, M. Bonori
One module for each
receiver in the landing station.
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
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)

Bilancio della Potenza per il
trasporto dati
•
•
•
•
•
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
