This exercise teaches you that media conversion is not magic. It is simply a Layer 1 (Physical) and Layer 2 (Data Link) pass-through. The "converter" ignores the packet contents; it just changes the physical signal from electrical (copper) to optical (fiber).
Once connected, the lights on the converter and connected devices should turn green.
When building labs in Cisco Packet Tracer, you will not find a standalone device explicitly labeled "Media Converter" in the component toolbar. Instead, Packet Tracer requires you to use specific modular devices or multi-port switches to convert signals between copper and fiber.

Simulating these links helps engineers plan real-world deployments. When a building-to-building run exceeds 100 meters, utilizing modular fiber slots within switches or deploying dedicated hardware media converters ensures that bandwidth remains uncompromised over long distances. Packet Tracer effectively teaches the underlying logic: data changes form across physical mediums, but upper-layer networking rules remain completely identical. media converter in cisco packet tracer link
Why use a media converter in a simulation? Here are typical educational scenarios and how to fix them.

If you are interested, I can provide a more complex lab scenario that includes VLANs and security configurations on top of this fiber connection.

Cisco Packet Tracer does not have a dedicated "Media Converter" appliance (like a $50 Startech box). However, we can use the (or an old Router with switching ports) to act as one.
This is the critical part. You cannot use automatic cable selection. You must manually choose the correct cable types.
Linking old copper-only switches to modern fiber backbones. Once connected, the lights on the converter and
Always check the cable types (Copper straight-through vs. Fiber) when creating your link. Packet Tracer will give a red "link down" icon if the connection is invalid—a sign that you may need a different interface or a simulated converter.
A acts as the bridge between these two worlds, translating electrical signals from copper twisted-pair cables into light signals for fiber optic lines.
