Cable Compendium: a guide to the week’s submarine and terrestrial developments

New call-to-action

20 Jan 2023

Telxius has teamed up with America Movil to deploy a new submarine cable between Guatemala, the US and Mexico, thus accelerating the digital connectivity across LATAM. Named AMX3 by America Movil and Tikal by Telxius, the new submarine cable system is described by the partners as ‘the highest capacity undersea cable’ to connect Puerto Barrios (Guatemala) with Boca Raton (US), with an additional possible landing in Cancun (Mexico). Featuring an initial estimated capacity of 190Tbps, AMX3/Tikal will be ready for service (RFS) in 2025. The supply contract with vendor Alcatel Submarine Networks (ASN) is already in force.

Globe has revealed that the 2,500km Philippine Domestic Submarine Cable Network (PDSCN) – a joint project developed by Globe in partnership with Eastern Communications and InfiniVAN – is on track for completion in April 2023. The project kickstarted in July 2022 in Subic (Zambales) and has landed at 20 sites so far. Going forward, in 2023 the nine remaining segments of the submarine cable will be deployed, connecting 13 cities, namely: Calatrava, Romblon; Pasacao, Camarines Sur; Bulan, Sorsogon; Calbayog City, Samar; Palanas, Masbate; Mactan, Cebu; Maasin City, Leyte; Claver, Surigao del Norte; Kinoguitan, Misamis Oriental; Camiguin; Dipolog, Zamboanga del Norte; Liloy, Zamboanga del Norte; and Zamboanga City, Zamboanga del Sur.

Infinera’s ICE6 800G coherent optical solution has been deployed to modernise and increase capacity on the transpacific Unity/EAC-Pacific submarine cable system, which spans 9,620km and directly connects Japan and the US. The infrastructure is owned and operated by a consortium comprising Bharti Airtel, Global Transit (a wholly-owned subsidiary of TIME), Google, KDDI Corp, Telstra and Singtel. By upgrading the network to ICE6, the consortium will be able to increase the life span of the cable by nearly 25% and deliver up to 7.4Tbps per fibre pair.

Zayo has strengthened its long-haul fibre network in France by deploying a 400Gbps route linking Paris and Marseille. With 24Tbps of total expected capacity, the new route will also provide direct access to Bordeaux, which will serve as a landing hub for the trans-Atlantic Amitie cable system, connecting the US to both the French Atlantic coast and the UK. The Amitie cable system is expected to go live in Q2 2023 with a capacity of over 320Tbps, connecting Boston (US) to Slough (UK) and Bordeaux (France).

Australasia-based Southern Cross Cables has launched commercial 400GbE services on its Southern Cross NEXT system between Australia, New Zealand and the US. The 400GbE service runs on Ciena’s 6500 Packet-Optical Platform, powered by WaveLogic 5 Extreme coherent optics and is managed by the Manage, Control and Plan (MCP) domain controller. To accommodate increasing and changing network traffic demands, Southern Cross’s eco-system also incorporates Ciena’s 5400 and 8700 platforms, providing the ability to deploy services from 100Mbps now up to 400GbE connectivity over applicable wavelengths. The availability of 400GbE services will allow customers hyper-scale low-latency connectivity directly between data centres in Sydney (Australia) and Los Angeles (US), with a new Auckland DC PoP due for implementation in 2023.

Lastly, the Telecom Regulatory Authority of India (TRAI) has extended the deadline for comments on its consultation paper called ‘Licensing Framework and Regulatory Mechanism for Submarine Cable Landing in India’. The paper is aiming to address concerns that some Indian International Long Distance Operators (ILDOs) that do not have any stakes in submarine cable systems are seeking clearance on behalf of the owners for laying or maintaining such cables in Indian territorial water or exclusive economic zones, and also for applying to set up Cable Landing Stations (CLS) for such submarine cables. The regulator is also seeking comments on submarine maintenance activities in and around Indian waters, deployment challenges and ways to overcome them to promote domestic submarine cables, issues related to establishing terrestrial connectivity between differently located CLS and ‘the benefits and challenges involved in laying stub-cables, a new concept of placing prelaid open-ended dark fibre from the CLS through Beach Manhole (BMH) into the territorial waters for upcoming new cables.’ Interested parties are now given until 10 February 2023 to submit their comments, while counter-comments will be accepted until 24 February 2023.
