Network administrators need to have a deep understanding of the characteristics of different types of media converters and make reasonable choices to meet actual network needs.

Prepare to connect media converters and switches

Let me give you a detailed introduction to the preparations you need to pay attention to when connecting media converters and switches:

Check the port type of the switch and media converter:

• First you need to confirm whether the port types available on the switch and media converter match.
• Check whether the switch’s ports are RJ-45, SFP, SFP+, or other types.
• Also confirm the interface type supported by the media converter, such as fiber optic LC, SC, or copper wire RJ-45.
• Mismatching port types will result in incorrect connection, and you need to select an appropriate transfer device.

How to choose the right connection cable:

• If both the switch and media converter use RJ-45 cable interfaces, you can use standard Ethernet cables.
• If one end is an optical fiber interface, the corresponding optical fiber jumper (such as LC-LC, SC-SC) needs to be used for connection.
• The length of the optical fiber jumper should be selected according to the actual deployment environment to ensure transmission quality.
• The model and quality of the cable will also affect the overall network performance, so you need to choose carefully.

Confirm power supply to media converters and switches:

• Check whether the media converter requires a separate power supply or can be powered via the switch port (PoE).
• If the media converter requires a separate power supply, ensure that the power supply specifications match the converter requirements.
• For media converters that can be powered through the switch port, ensure that the switch port supports the required PoE standard.
• Insufficient power supply will cause the media converter to fail to work properly and needs to be confirmed in advance.

Example:

The switch port is SFP+ and the media converter is fiber optic to RJ-45. You need to prepare an LC-LC optical fiber jumper for connection. Also confirm whether the media converter requires an independent power supply. In short, when preparing to connect media converters and switches, it is necessary to comprehensively consider factors such as interface type matching, cable selection, and power supply to ensure that the entire network equipment can be reliably interconnected.

Steps to connect media converter and switch

Next, I will give you a detailed introduction to the specific steps for connecting the media converter and switch:

Use the correct connection cable to connect the media converter to the switch:

• Select the appropriate fiber optic jumper or Ethernet cable based on the interface type confirmed previously.
• Connect one end of the cable to the corresponding port on the media converter, and the other end to the corresponding port on the switch.
• For fiber optic connections, ensure the insertion and extraction direction and alignment of the fiber optic connector are correct.
• For Ethernet cable connections, pay attention to the use scenarios of straight-through cables or crossover cables.

Check whether the connection is secure and confirm that the indicator light is working properly:

• Check carefully whether the cable connector is fully inserted and fastened to avoid poor contact.
• Observe the lights on the media converter and switch to confirm that the connection is good.
• The indicator light may have different status indicators such as Link, Act, Speed, etc., please judge according to the instructions.
• If the indicator light displays abnormally, you may need to check the cable or rewire it.

Configuring settings for media converters and switches:

• Log in to the switch CLI and check whether the port’s speed and duplex mode are configured correctly.
• If port auto-negotiation fails, you can manually set the port speed and duplex.
• For the media converter, you may also need to configure some parameters, such as MDI/MDIX mode, etc.
• Ensure that the media converter and switch port configurations match correctly.

Example:Connect the SFP+ to RJ-45 media converter to the switch’s SFP+ port:
