New Submarine Cable For South East Asia
POET Taps Lumentum For Data Centre Solutions
A consortium of telecommunication
POET Technologies Inc. will use high-speed directly modulated laser (DML) technology from Lumentum Holdings Inc. to enable high volume, low power, and cost-efficient 400G, 800G, and 1.6T pluggable transceivers for hyperscale data centres. Working with Lumentum, POET expects to start sam- pling the 400G FR4 transmit optical engines with inte- grated drivers in the first half of 2023 and production by the second half of 2023. The 400G FR4 optical engines are architected as photonic chip- lets and will be the industry’s first implementation of DMLs with flip-chip integration on an optical interposer at these data rates. With the small size and elegant design of POET’s
Philippines, Brunei Darus- salam and Hainan, China. HMN Technologies Co., Lim- ited (HMN Tech) was awarded as the system supplier and is expected to complete the construction of ALC by the third quarter of 2025. ALC is seen to provide additional hyper-capacity within Asia and boost resiliency for inter- national traffic. It will have a minimum eight fibre pairs in the system, with 18 Tbps/fibre pair minimum trunk design capacity, adding more capac- ity and diversity to existing networks in the region. An open cable system architec- ture will be adopted for ALC, enabling operators to select and maintain independent line terminal equipment that would suit their customer requirements.
optical engines, customers will have the flexibility to design 400G, 800G, and 1.6T pluggable transceivers using the same 400G FR4 chiplets. “The majority of the 400G transceivers in the market today use either externally modulated lasers or silicon photonics combined with ex- ternal lasers. These solutions require multiple components and involve several cum- bersome and costly active alignments,” said Suresh Ven- katesan, chairman & CEO of POET. “POET has a significant opportunity to disrupt the market with a highly integrat- ed solution with all passive alignments and monolithically integrated waveguides and multiplexers, which translates to lower cost, power, and size benefits to our customers.”
companies led by Singapore operator Singtel, has signed agreements to invest about US$300 million for a submarine cable system in South East Asia that aims to boost data capacity in the region and upgrade local capacities. The group also includes China Telecom Global Limited of China, Globe Telecom, Inc., DITO Telecommunity Corporation of the Philippines, and Unified National Networks Sdn Bhd of Brunei Darussalam. The planned Asia Link Ca- ble (ALC) will be approximate- ly 6,000-kilometre in length, connecting Hong Kong SAR, China and Singapore as its trunk, with branches into the
