Key Terms

submarine cable technical

Submarine cables are long, insulated fiber-optic lines laid on the ocean floor that carry the bulk of international internet, phone and data traffic—think of them as underwater highways for digital information. They matter to investors because their construction, ownership and operation involve large capital spending, revenue streams and geopolitical or outage risks that can affect telecom, cloud and infrastructure companies’ performance and the reliability of global data networks.

spectral efficiency technical

Spectral efficiency measures how effectively a communication system uses its available frequency space to transmit data. It indicates how much information can be sent over a specific bandwidth within a given time, similar to how a highway lane can carry a certain number of cars per hour. Higher spectral efficiency means more data is transmitted with less wasted space, which can lead to faster and more reliable communication for users and better performance for service providers.

network control technical

Network control is the ability to manage and direct how a group of connected systems, devices or services communicate and operate, similar to a traffic manager deciding which lanes cars use and when. For investors it matters because control determines service reliability, costs, security and the power to roll out new products or restrict competitors — all of which affect revenue, regulatory risk and company value.

automation technical

Automation is the use of technology to perform tasks with minimal human intervention, often replacing manual work with machines or software. It matters to investors because it can increase efficiency, reduce costs, and enable faster decision-making, potentially leading to higher profits and competitive advantages for businesses.

fiber optic technical

Fiber optic is a technology that uses thin glass or plastic strands to carry data as pulses of light, like a very fast, flexible highway for information. It matters to investors because it underpins high-speed internet, cloud services and telecommunications — driving demand for network upgrades and long-term infrastructure spending that can boost revenue for companies that build, operate or supply fiber networks.

JAKARTA, Indonesia--(BUSINESS WIRE)-- Biznet, an integrated digital infrastructure company in Indonesia, has deployed Ciena’s (NYSE: CIEN) WaveLogic 5 Extreme (WL5e) on the international link of its submarine cable Biznet Nusantara Cable System-1 (BNCS-1), providing inter-island connectivity across Java, Sumatra and Bangka Islands. This upgrade aims to deliver 400G high-speed services, faster and more reliable internet connectivity, while also accelerating digitalization in Indonesia by enhancing the capacity of links connecting local and global networks.

“In today’s increasingly hyper-connected world, Biznet continues to focus on creating innovative services, meet ever-changing bandwidth demands, and deliver an incredible customer digital experience,” said Adi Kusma, President Director, Biznet. “We have a long history working with Ciena, and its WaveLogic technology allows us to meet our commitment in providing faster and more reliable services for today’s digital era, while accelerating digital transformation in Indonesia,” he added.

Ciena Services and Ciena partner Terrabit Networks are jointly supporting the design and deployment of Ciena’s 6500 powered by WL5e to drive seamless integration with other Biznet Fiber networks. Additionally, Biznet is using Ciena’s Navigator Network Control Suite to access advanced network control, planning, and automation capabilities, resulting in more efficient operations and faster provisioning.

“Indonesia is a key connectivity hub in Southeast Asia and demand for high-capacity, low-latency connectivity continues to grow exponentially in the AI era,” said Alex Wong, Regional Managing Director, ASEAN, Ciena. “By upgrading the BNCS-1 submarine fiber optic network, Biznet can deliver faster internet services, improve spectral efficiency, and support long-term growth.”

This initiative expands on Biznet’s earlier collaboration with Ciena to support its network expansion across Java, Bali, Sumatra, Batam, Bangka, Kalimantan, Sulawesi and Flores islands. Beyond increasing capacity on BNCS-1, this upgrade also improves capacity on the Batam–Singapore link, enabling better and higher international gateway capacity, faster access to global services, and delivers more stable and reliable connections for customers.

“As we enter the AI era, internet connectivity goes beyond necessity, it is the core foundation for delivering faster, stable and seamless digital experiences. Therefore, our collaboration with Ciena in advancing network infrastructure and connectivity is a strategic move to ensure optimal service delivery,” Adi concluded.
