In 2024, as the Northern Mariana Islands (CNMI) pushed forward with its digital transformation plan to expand high-speed broadband coverage across the archipelago, a local leading telecommunications operator faced critical challenges in its communication infrastructure upgrade project. The project aimed to replace outdated cables, expand network coverage to remote islands, and support the territory’s goal of achieving universal broadband access, as part of the U.S. federal Broadband Equity, Access, and Deployment (BEAD) program. Tasked with delivering reliable, durable, and efficient cabling solutions, the client turned to Dongguan GERITEL Electrical Co., Ltd.—a trusted provider of high-quality wires and cables with global certifications and rapid delivery capabilities. This case study details how our tailored solutions, featuringAerial Cable, Elastomer Cable, and Medium Voltage Cable, solved the client’s core pain points and contributed to the success of this landmark infrastructure project.

1. Challenges in the Northern Mariana Islands’ Communication Upgrade

The Northern Mariana Islands, a U.S. territory in the western Pacific, consists of 14 islands with scattered populations and diverse geographical conditions—from coastal areas prone to typhoons to mountainous regions with difficult terrain. The client, a key telecommunications service provider in the region, was responsible for upgrading the existing communication network to support DOCOMO PACIFIC’s 1Gbps high-speed broadband rollout and meet the growing demand for stable internet access in homes, businesses, and community institutions. However, several critical pain points threatened to delay the project and compromise its quality:

First, the outdated cabling system was unable to withstand the territory’s harsh environmental conditions. Typhoons, high humidity, and salt spray often damaged conventional cables, leading to frequent network outages and high maintenance costs. The client needed cables that could resist corrosion, extreme temperatures, and mechanical stress. Second, the project required a mix of overhead and indoor/outdoor cabling solutions, each with unique performance requirements—overhead cables needed high tensile strength, while indoor/outdoor cables required flexibility and resistance to oil and chemicals. Third, as a project funded by federal programs, the client had strict quality standards and required cables with internationally recognized certifications to ensure compliance with regional regulations. Finally, the project had a tight timeline to meet the BEAD program’s milestones, and delays in cable delivery would have disrupted the entire upgrade schedule, leading to financial penalties and unmet service commitments.

After evaluating several suppliers, the client chose Dongguan GERITEL Electrical Co., Ltd. for three core reasons: our SAA certification (a key mark of quality for electrical products in the Asia-Pacific region), our proven track record of delivering high-quality cables for infrastructure projects, and our commitment to rapid delivery—even for large-scale, customized orders. The client also valued our ability to provide technical support and tailored solutions to address their unique environmental and project-specific needs.

2. Choosing the Right Cables for the Project

After conducting a detailed assessment of the project’s requirements—including terrain, environmental conditions, and performance needs—our team recommended a combination of Aerial Cable, Elastomer Cable, and Medium Voltage Cable, along with complementary low voltage cable for secondary distribution. Each cable type was selected for its unique advantages, addressing specific pain points and outperforming alternative options:

2.1 Aerial Cable: Reliable Overhead Transmission for Remote Areas

For the overhead portion of the project—connecting main network hubs across islands and remote regions—we supplied Aerial Cable (model: ABC 12.7/22kV) with specifications including 3×70+1×50mm² and 3×95+1×70mm². This cable was chosen over traditional overhead conductors for several key reasons: it features a bundled design with XLPE insulation and a galvanized steel messenger wire, providing superior tensile strength to withstand strong typhoon winds (up to 150km/h) and mechanical stress during installation. Unlike bare overhead conductors, our Aerial Cable has integrated insulation, reducing the risk of short circuits caused by debris or salt spray, and eliminating the need for additional insulation layers—lowering both installation and maintenance costs. The XLPE insulation also ensures excellent thermal stability, allowing the cable to operate in temperatures ranging from -40°C to 90°C, which is critical for the Northern Mariana Islands’ tropical climate with high heat and humidity.

2.2 Elastomer Cable: Flexible and Durable for Complex Installations

For indoor and outdoor installations in difficult-to-reach areas—such as underground ducts, building interiors, and near coastal industrial zones—we provided Elastomer Cable (model: HO7RN-F) in sizes 2×1.5mm², 3×2.5mm², and 4×4mm². This cable is made with rubber insulation (elastomeric material), which offers exceptional flexibility compared to PVC or XLPE cables. Its flexibility allows it to be bent and routed around obstacles—such as tight corners in buildings or uneven terrain in remote areas—without damaging the insulation or reducing performance. Additionally, our Elastomer Cable is resistant to oil, acids, alkalis, and saltwater corrosion, making it ideal for coastal environments where salt spray is a constant threat. Unlike rigid PVC cables, which can become brittle in extreme temperatures, the elastomeric material maintains its flexibility and durability even in the territory’s hot, humid conditions, reducing the risk of cable failure and maintenance costs. This cable also served as a key low voltage cable solution for secondary power distribution in residential and commercial areas, ensuring safe and reliable power supply to end-users.

2.3 Medium Voltage Cable: Stable Power Transmission for Network Hubs

To connect major network hubs and transmit power efficiently across long distances, we supplied Medium Voltage Cable (model: MV-90 12.7/22kV) with specifications 3×120mm² and 3×150mm². This cable features XLPE insulation and a copper conductor, providing excellent electrical conductivity and thermal stability. It is designed to operate at medium voltage (12.7/22kV), making it suitable for transmitting power from substations to network hubs, where it is then stepped down to low voltage for distribution. OurMedium Voltage Cable is resistant to mechanical damage and moisture, ensuring stable performance even in underground or wet environments. Compared to traditional paper-insulated medium voltage cables, our XLPE-insulated version offers longer service life (up to 30 years), lower dielectric loss, and easier installation—reducing project time and long-term maintenance costs. Its compliance with international standards also ensured the client met the BEAD program’s quality requirements.

3. Backed by SAA Certification

Quality and safety were non-negotiable for this project, as it directly impacted the reliability of the Northern Mariana Islands’ communication network and the safety of installation workers. All cables supplied for the project were fully compliant with international standards (IEC 60502, AS/NZS 5000.1) and SAA certification—an internationally recognized mark of quality that confirms our products meet strict safety and performance requirements for the Asia-Pacific region. This certification was a key differentiator for our client, as it ensured the cables would pass local inspections and meet the federal BEAD program’s compliance standards.
