Telecommunications giant PLDT Inc. has enhanced its domestic backhaul network by deploying Ciena’s optical technology to support the Asia Direct Cable (ADC) system, aiming to improve data transmission from international routes to local users across the Philippines.
PLDT is using Ciena’s 6500 platform powered by WaveLogic 5 Extreme (WL5e) coherent optical technology to increase network capacity and reliability for backhauling traffic from global cloud providers. The move is part of the company’s effort to strengthen the country’s digital infrastructure and ensure high-speed, low-latency connectivity nationwide.
“PLDT is committed to strengthening the country’s digital backbone by ensuring that the international capacity carried by the ADC system translates into world-class connectivity for users nationwide,” said Blums Pineda, senior vice president and head of Enterprise Business Group at PLDT and Smart. “With the support of Ciena’s optical technology, we can provide faster, more resilient, and more secure services, powering the Philippines’ digital economy from individual users to enterprises and hyperscalers.”
Ciena’s WL5e technology enables PLDT to handle multi-terabit traffic, delivering high-capacity and low-latency connections from the ADC landing station to its national backbone. The company is also using Ciena’s Navigator Network Control Suite (Navigator NCS) to streamline network planning, provisioning, and assurance processes, enhancing operational efficiency.
Matt Vesperman, vice president for Asia Pacific at Ciena, said the Philippines plays a crucial role in regional data connectivity. “Ciena’s market-leading optical technology provides a seamless connectivity link to advance international trade and digital transformation within the Philippines,” he said.
PLDT, through its enterprise arm, continues to expand its digital investments to support business operations and innovation. The ADC system is connected to the newly launched VITRO Santa Rosa (VSR), the country’s first AI-ready data center operated by VITRO Inc. Ciena’s technology also powers VITRO’s Data Center Interconnect (DCI) solution, which links VSR to other VITRO facilities, allowing enterprises to securely connect their systems across multiple sites and improve disaster recovery and operational efficiency.
