You connect fiber optic cable to copper cable using a device called a fiber optic media converter.
Here's a breakdown of the process:
Understanding the Difference
Fiber optic cables transmit data using light signals, while copper cables use electrical signals. Therefore, a direct physical connection is impossible. A media converter acts as a translator between these two different signal types.
The Role of the Fiber Optic Media Converter
A fiber optic media converter is a simple networking device that allows you to connect different media types, such as fiber optic cable to twisted pair copper cable (e.g., Ethernet). It effectively bridges the gap between the two technologies.
How It Works:
-
Signal Reception: The converter receives the electrical signal from the copper cable (typically Ethernet).
-
Conversion to Light: The converter's internal circuitry transforms this electrical signal into a light signal.
-
Transmission Over Fiber: The light signal is then transmitted through the fiber optic cable.
-
Reception at the Other End: At the receiving end, another media converter is needed. It receives the light signal from the fiber optic cable.
-
Conversion Back to Electrical Signal: This second converter transforms the light signal back into an electrical signal.
-
Transmission Over Copper: Finally, the electrical signal is transmitted through the copper cable to the destination device.
Key Considerations:
- Fiber Type: Ensure the media converter supports the type of fiber optic cable you're using (single-mode or multi-mode).
- Connector Type: Verify the fiber optic connector type (e.g., SC, LC, ST) is compatible with the converter.
- Ethernet Speed: Choose a converter that supports the appropriate Ethernet speed (e.g., 10/100/1000 Mbps).
- Distance: Consider the maximum distance supported by the fiber optic cable and the media converter.
Example:
Imagine you want to connect two Ethernet switches that are too far apart to use copper Ethernet cables directly. You would:
- Connect a copper Ethernet cable from the first switch to a fiber optic media converter.
- Connect a fiber optic cable from the media converter to another media converter located near the second switch.
- Connect a copper Ethernet cable from the second media converter to the second switch.
This setup effectively extends your Ethernet network using fiber optic cabling.
Table Summarizing Media Converters
| Feature | Description |
|---|---|
| Function | Converts electrical signals (copper) to light signals (fiber) and vice versa. |
| Fiber Types | Supports single-mode and multi-mode fiber. |
| Ethernet Speeds | Supports 10/100/1000 Mbps and higher. |
| Connector Types | Supports various fiber connectors (e.g., SC, LC, ST). |
