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.
