HFC contains
The correct answer is option 'C' - Both of the mentioned.

Explanation:
HFC stands for Hybrid Fiber Coaxial, which is a telecommunications network technology that combines both fiber optic cables and coaxial cables to provide high-speed data transmission and communication services.

Fibre Cable:
Fiber optic cables are made of thin strands of glass or plastic that transmit data as pulses of light. They have a high data carrying capacity and can transmit data over long distances without any loss of signal quality or interference. Fiber optic cables are used for the backbone of the HFC network, connecting the central office or headend to the distribution points.

Coaxial Cable:
Coaxial cables consist of a central conductor, an insulating layer, a metallic shield, and an outer insulating layer. They are used to carry electrical signals and are capable of transmitting high-frequency signals. Coaxial cables are used in the last mile of the HFC network, connecting the distribution points to the end users' premises.

Hybrid Fiber Coaxial (HFC) Network:
In an HFC network, fiber optic cables are used for the long-distance transmission of data, while coaxial cables are used for the last mile connectivity. The combination of fiber optic cables and coaxial cables allows for high-speed data transmission and supports various services such as cable TV, internet, and telephone.

Key Points:
- HFC stands for Hybrid Fiber Coaxial.
- HFC network combines both fiber optic cables and coaxial cables.
- Fiber optic cables are used for long-distance transmission.
- Coaxial cables are used for the last mile connectivity.
- HFC network supports services like cable TV, internet, and telephone.

Conclusion:
The correct answer to the given question is option 'C' - Both of the mentioned, as HFC contains both fiber optic cables and coaxial cables in its network architecture.
