You connect fiber optic cable to coaxial cable using a fiber media converter. This device bridges the gap between these two different types of cabling.
Understanding the Difference
- Fiber Optic Cable: Transmits data as light signals, offering high bandwidth and long-distance capabilities.
- Coaxial Cable: Transmits data as electrical signals, typically used for shorter distances and lower bandwidth applications.
The Role of the Fiber Media Converter
A fiber media converter is the key to connecting these two disparate systems. It performs the following functions:
- Optical to Electrical Conversion: It receives the light signal from the fiber optic cable and converts it into an electrical signal.
- Electrical to Optical Conversion: (In the reverse direction) It receives the electrical signal from the coaxial cable and converts it into a light signal.
How it Works
- Fiber Optic Connection: One end of the fiber media converter is connected to the fiber optic cable using appropriate fiber connectors (e.g., SC, LC).
- Coaxial Connection: The other end of the media converter connects to the coaxial cable, typically using a BNC connector.
- Power Supply: The media converter requires a power supply to operate.
- Signal Conversion: The media converter automatically converts the signals between the two cable types.
Key Considerations When Choosing a Fiber Media Converter:
- Fiber Type: Ensure the converter supports the type of fiber optic cable you are using (single-mode or multi-mode).
- Wavelength: Confirm the wavelengths are compatible.
- Data Rate: The converter should support the required data rate for your application.
- Coaxial Cable Type: Consider the type of coaxial cable (e.g., RG-6, RG-59) and choose a converter with compatible connectors.
- Distance: Verify that the media converter supports the distance requirements of your network.
Simplified Explanation
Think of a fiber media converter as a translator. It understands both the language of fiber optics (light signals) and the language of coaxial cable (electrical signals) and translates between them, allowing the two to communicate.
