Fiber to the Curb (FTTC)
FTTC is a hybrid fiber architecture where fiber optic cables extend to a distribution point near the customer's premises (typically at the curb or utility pole), and the final connection uses existing copper or coaxial cables. This approach combines the benefits of fiber with the cost-effectiveness of utilizing existing last-mile infrastructure.
FTTC brings fiber much closer to end users than FTTN, typically within 300 meters of the premises. This shorter copper run allows for significantly higher speeds than traditional broadband while maintaining lower deployment costs compared to full FTTH.
The distribution point (DP) or optical network unit (ONU) at the curb converts the optical signal to electrical signals that can travel over the existing copper infrastructure to the customer's premises.
Key Features and Benefits
Applications
FTTC is well-suited for residential neighborhoods and suburban areas where running fiber to every home would be expensive, but higher speeds than FTTN are desired. It's particularly effective in areas with good existing copper infrastructure.
Performance
With fiber extending to the curb, FTTC can deliver speeds comparable to many FTTH deployments, especially with modern technologies like G.fast or VDSL2. The short copper run ensures minimal signal degradation and high reliability.
Future-Proof
FTTC infrastructure can be easily upgraded to full FTTH by simply extending the fiber from the curb to individual premises when needed. This provides flexibility for future network evolution.
