A regional internet service provider selected YITOFC fiber optic cables for an FTTH community deployment project designed to provide high-speed broadband access to apartments, villas, commercial units and community facilities.
The network was built using outdoor fiber distribution cables, fiber distribution boxes and FTTH drop cables. This structure enabled the operator to extend fiber connectivity from the local access node directly to individual subscribers.
The project was designed for fast installation, reliable optical performance and future subscriber expansion.

Project Background
The customer needed to upgrade an existing residential broadband network and provide fiber connectivity directly to each home.
The community included:
- Multi-story apartment buildings
- Residential villas
- Commercial shops
- Security offices
- Community service facilities
- Underground communication ducts
- Pole-mounted distribution routes
The network had to support current broadband demand while allowing future expansion without replacing the main distribution infrastructure.
Customer Requirements
The customer required a solution that could:
- Deliver fiber directly to each subscriber
- Support stable high-speed internet services
- Reduce installation time
- Simplify cable routing inside buildings
- Provide low bending loss
- Support aerial and duct installation
- Allow future subscriber expansion
- Reduce maintenance requirements
- Provide customized cable printing and packaging
YITOFC Solution
After reviewing the network layout, YITOFC recommended a combination of outdoor distribution and FTTH drop cables.
Main Distribution Network
Recommended products: GYTS fiber optic cable, GYXTW fiber optic cable, GYFXTY fiber optic cable.
These cables were used to connect the local optical line terminal or access node to community distribution points.
Building Distribution
Small-diameter indoor and outdoor cables were used to connect building entrances, floor distribution boxes, communication rooms and optical distribution frames.
Subscriber Drop Connection
Recommended products: GJYXCH self-supporting FTTH drop cable, GJXH indoor FTTH drop cable.
G.657.A1 bend-insensitive fiber was selected for routes involving corners, wall mounting and compact indoor spaces.

Cable Deployment
Outdoor Backbone
Outdoor fiber cables connected the ISP access node to the residential community.
The cable structure was selected according to duct availability, pole routes, required fiber count, outdoor exposure and installation distance.
Community Distribution
Distribution cables connected different residential blocks and local fiber distribution boxes.
Spare fibers were included for future buildings, additional subscribers, network redundancy, security systems and community Wi-Fi.
Building Entry
Indoor or outdoor-to-indoor cables were used between the building entrance and internal fiber distribution points.
Final Drop
FTTH drop cable connected each optical distribution box to the subscriber optical network terminal.
Recommended Products
| Network Section | Recommended Product |
| Community backbone | GYTS |
| Local distribution | GYXTW / GYFXTY |
| Building connection | Indoor fiber optic cable |
| Aerial subscriber drop | GJYXCH |
| Indoor subscriber drop | GJXH |
| Fiber management | Distribution box / patch panel |
| Optical splitting | PLC splitter |
| Subscriber connection | Fiber patch cord |
Project Advantages
Direct Fiber Access
Fiber connectivity was extended directly to homes and businesses, supporting reliable broadband transmission.
Fast Installation
Compact drop cables and pre-planned distribution points reduced installation time.
Low Bending Loss
G.657 bend-insensitive fiber helped maintain optical performance in narrow indoor routes and around corners.
Easy Subscriber Expansion
Reserved fibers and modular distribution boxes allowed new subscribers to be added without replacing the backbone.
Flexible Installation
The selected cable range supported duct, aerial, wall-mounted and indoor installation.
Lower Maintenance
A well-structured FTTH network reduced unnecessary joints and simplified future maintenance.
