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

This Optical Module (S-1.1) will be used as Electrical/Opticalconverter within the customer equipment in both sides, undersea and in the landing station.

Consume = 1,5 W

One module for eachfloor of the tower.

One module for eachreceiver in the landing station.

Martina Franca, 14 Dec 2001, M. Bonori

8

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

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
