How a Regional Telecom Provider Reduced Aerial Network Failures by 55% with GYTC8S Fiber Optic Cable

Customer Background

A regional telecommunications provider in Southeast Asia specializing in FTTH (Fiber-to-the-Home) services was expanding its network into rural and suburban areas. The company served over 500,000 subscribers across a region characterized by dense vegetation, seasonal monsoons, and strong winds. With a mandate to improve connectivity in underserved communities, the provider faced the dual pressure of rapid expansion and maintaining service reliability on a limited budget.

Challenges with Aerial Fiber Deployment

The provider's existing aerial fiber network, installed over three years ago, relied on standard loose tube cables without adequate armoring. Over time, the network suffered from frequent outages due to weather-related stress (wind, rain) and physical damage from falling tree branches and rodent activity. The average monthly failure rate stood at 12 incidents per 100 km of aerial cable, leading to customer complaints and penalty fees from regulatory bodies. Maintenance crews spent an average of 4 hours per repair, and spare parts inventory costs were climbing. The customer churn rate increased by 8% over two years, impacting revenue.

Why Choose the GYTC8S Fiber Optic Cable?

After assessing several alternatives, including ADSS (All-Dielectric Self-Supporting) cables and traditional armored cables, the provider chosen the GYTC8S fiber optic cable. The key decision factors were:

• Steel wire armoring: Provided superior mechanical protection against impacts and gnawing animals.
• PE (Polyethylene) sheath: Offered excellent moisture and UV resistance for outdoor use.
• Compliance with IEC 60794 standards: Ensured consistent performance and reliability.
• Cost-effectiveness: Lower total cost of ownership compared to heavier armored cables, while still providing robust protection.

Implementation Process

The project covered 200 km of aerial routes in phases over six months. The implementation steps were:

1. Route survey: Identified high-risk areas and optimized cable paths.
2. Procurement and logistics: Ordered custom lengths of GYTC8S with tension members specific to the spans.
3. Installation: Used professional rollers and tensioners to prevent sheath damage during pulling.
4. Splicing and testing: Performed fusion splicing and OTDR testing to verify low loss.
5. Commissioning: Integrated new sections into the live network with minimal disruption.

A challenge encountered was the cable's stiffness during installation in tight bends. The team resolved it by using larger-radius pulleys and slower pulling speeds, as recommended by the manufacturer.

Quantifiable Results

Within six months of completing the rollout, the provider observed significant improvements:

• 55% reduction in aerial network failure incidents (from 12 to 5.4 incidents per 100 km per month).
• Annual maintenance cost savings of $80,000 due to fewer dispatches and lower spare parts usage.
• Average repair time decreased from 4 hours to 1.5 hours because remaining faults were easier to locate and fix.
• Customer satisfaction scores improved by 12 percentage points (from 78% to 90%) as service reliability increased.

Customer Testimonial

"The GYTC8S cable has been a cornerstone of our network upgrade. Failures that used to disrupt service for hours are now rare. We have regained the trust of our customers and can confidently plan further expansions," said the provider's Director of Network Operations.

Lessons and Recommendations

• Invest in armored cables for exposed routes: The upfront cost is offset by long-term operational savings.
• Training is essential: Proper handling techniques ensure the cable's protective features are fully utilized.
• Plan for environmental extremes: Consider local climate and wildlife activity when choosing cable types.
