Cuba-Venezuela Specific Topics

Embargo

Alcatel, Alcatel Shanghai Bell, Alcatel Submarine Networks are committing to
deliver the project while respecting Embargo policy

Alcatel group and ASN are french registered companies

Alcatel Shanghai Bell is a chinese registered company

Specific embargo clauses will be part of the T&C’s to ensure our commitment for
the whole life of the project

URC1 cable (Nexans)

1.

no vault design , cannot be deployed above 1500m. On Cuban side water depth is more than
5000m

2.

is only suitable for shallow water conditions (> 1500 m) and UNREPEATERED APPLICATIONS
ONLY: no vault, no copper conductor, no operational margin commensurate with repeatered
solution deployment.

3.

Only 3000 km have been installed all below 1000 m

OALC5 cable ( ASB )

1.

vault design , can be deployed and recovered down to 8000m

2.

More than 250 000 Km OALC optical package

Repeater

Repeater
ASB proposal :

1.

ASN repeaters; No US component & No US patent

2.

Over 4300 have been installed without any failure

Huawei proposal :

1.

Red Sky repeaters US component & 41 US patents

2.

Not a single repeater has been deployed as of yet

System assembly before loading (ensure that link is working well before loading)

Not possible in Rognan factory ( Nexans)
Possible in Calais ( ASN factory) System assembly and full integration will be done in Calais

The « Red Sky » repeater :none in service

The GMSL repeater (based on cable joint box) offers:

No internal atmosphere control 





Accelerated ageing & degraded reliability

No hermetic housing sealing 





 Cable break can mean repeater replacement

Limited thermal management 





 Small size impairs heat dissipation, accelerates ageing

and degrades reliability

No repeater supervisory system 





 Cannot locate faulty repeater/spans

Fault Location by using external C-OTDR 





 Dependant on external sources, not existing in

the market place today

Conclusions: ASB versus Huawei offer

Wet products

Wet plant is the cost driver (Nexans, GMSL, Red Sky)

URC-1: no vault, no copper tube, not suitable for 5000 m depth

Red Sky repeater: not qualified, not proven, never deployed, US design

Solution

Reliability and maintainability are keys

ASB’s solution 5 times more reliable – Maintainable at minimal costs

Huawei’s solution 25 year life time will be a challenge
