Underground Fiber Infrastructure for Modern Telecom Networks
A regional telecommunications contractor selected YITOFC GYTS and GYTA Fiber Optic Cables for an underground duct network project designed to expand metropolitan broadband capacity and improve long-term network reliability.
The project connected central offices, POP sites, data centers, enterprise districts and residential broadband access nodes through an underground duct system, providing a stable and scalable optical backbone for future service growth.
Project Information
| Project Type | Telecom Duct Fiber Cable Project |
| Region | Southeast Asia |
| Customer | Telecom Contractor |
| Network Type | Underground Fiber Backbone |
| Installation Method | Underground Duct |
| Cable Types | GYTS / GYTA |
| Fiber Type | G.652.D |
| Fiber Count | 48F / 96F / 144F |
| Application | Metro Backbone & Broadband |
Project Background
The telecom operator planned to expand its metropolitan fiber network to support:
- Residential FTTH services
- Enterprise leased lines
- Government communication
- Data center connectivity
- Mobile base station backhaul
- Future 100G/400G transmission
Because the city already had underground communication ducts, duct installation was selected to protect the network while minimizing visual impact.
Customer Requirements
The customer required:
- Reliable underground fiber infrastructure
- Low optical attenuation
- Water-resistant cable construction
- Easy cable pulling in ducts
- High fiber-count backbone capacity
- Long service life
- Low maintenance costs
- Future network expansion capability
