    Consortium contracts ASN for INDIGO cable system

    A consortium consisting of Asian operators, Google and telecommunications infrastructure company Superloop have commissioned a new subsea able system linking Singapore, Indonesia and Australia.

    Singtel, Indonesia’s Indosat Ooredoo as well as Australia’s Telstra and education sector network provider AARNet have joined Google and Superloop’s SubPartners to join the INDIGO cable system.

    The cable system, formerly known as APX West and Central, will be deployed by Alcatel-Lucent Submarine Networks.

    It will span around 9,000km between Singapore and Perth on the west coast of Australia, and onwards to Sydney on the east coast. A ranching unit with two additional fiber pairs will connect Singapore and Jakarta.

    Construction of the cable is expected to be complete by mid-2019. The system will use an open cable two fiber pair desgin, providing consortium members with spectrum ownership and giving them the ability to independently adopt technology advancements and upgrades as required.

    “With internet data consumption growing by 70% in Asia last year alone these sorts of investments in international networks are critical for meeting the needs of connected consumers and businesses,” Telstra group MD for global services and international David Burns said.

    “The construction of INDIGO is timely to meet the rising demand for high-speed broadband between Asia and Australia. This cable system complements our global connectivity that links Asia, the US, Europe, Australia and the Middle East,” Singtel Enterprise VP for carrier services Ooi Seng Keat added.

    Superloop has inherited its membership in the INDIGO consortium via the recent acquisition of subsea cable operator SubPartners for $2.5 million. As part of the acquisition Superloop has provided a guarantee involving the meeting of SubPartners’ construction capex costs for the project.

    ASN, Bell Labs set 65Tbps subsea cable speed record

    Alcatel-Lucent Submarine Networks and Nokia Bell Labs have set a new transmission record over a 6,600km single mode fiber for transoceanic cable systems.

    The lab trial achieved a total transmission speed of 65Tbps using submarine grade dual band erbium doped fiber amplifiers.

    The trial used Bell Labs’ new probabilistic constellation shaping (PCS) modulation technology. PCS is designed to maximize the distance and capacity of high-speed transmission in optical networks, by using non-uniform transmission of constellation symbols to increase resilience to noise and other impairments.

    “The future digital existence where everyone, everything and every system and process is connected will require a massive increase in network capacity and the ability to dynamically optimize this capacity,” Nokia CTO and Bell Labs president Marcus Weldon said.

    “Probabilistic constellation shaping extends the limits of current optical transmission by utilizing novel modulation techniques to dramatically improve the performance and capacity needed for the new digital era that will be enabled by the Future X Network.”

    The same technology was used in September to achieve speeds of 1Tbps per channel https://www.telecomasia.net/content/bell-labs-achieves-1tbps-over-fiberover Deutsche Telekom’s terrestrial optical network during trials with the operator’s T-Labs and the Technical University of Munich.

    A capacity of 65Tbps is 13,000 times the capacity of the first subsea amplified transatlantic system in 1995.
