Basic overview of media converters

Let me introduce the basics of media converters:

Media converter functions and types:

  • A media converter is a network device used to connect and convert different types of network transmission media.
  • It can realize interconnection and conversion between different network media such as fiber to copper, 10/100Mbps to Gigabit Ethernet, etc.
  • Common media converter types include fiber to copper converters, Ethernet to POF converters, etc.

Common media converter interface standards:

  • Media converters usually use standard Ethernet interfaces, such as RJ-45 or SFP/SFP+.
  • On the fiber side, the media converter can support common fiber interfaces such as LC, SC, and ST.
  • Some dedicated media converters can also support special optical fiber interfaces such as MTRJ and VF-45.
  • The interface type of the converter needs to match the network equipment and transmission medium.

The importance of media converters in network device integration:

  • Media converters can realize interconnection and communication between different network devices, making up for the differences in physical interfaces.
  • In the process of network upgrade or heterogeneous device integration, media converters play a key intermediate conversion role.
  • It enables devices with different network interfaces to be seamlessly connected, improving the flexibility and interoperability of the network.
  • Rational use of media converters can reduce the cost of network transformation and extend the service life of existing equipment.

In general, media converters are an important bridge to interconnect heterogeneous network devices and play an irreplaceable role in network integration and upgrades. 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:

  1. Use LC-LC fiber optic patch cords to connect the fiber optic port of the media converter to the SFP+ port of the switch.
  2. Check whether the optical fiber connector is fully inserted and whether the indicator light shows normal connection status.
  3. Log in to the switch CLI and check whether the SFP+ port configuration is set to auto-negotiation or 1000Mbps full-duplex.
  4. If necessary, you can also set some parameters on the media converter to ensure that it matches the switch port.

Through the above steps, you can complete the correct connection and configuration of the media converter and switch to ensure that the two can communicate smoothly.

How to verify connectivity between media converter and switch

After completing the connection and configuration of the media converter and switch, the next step is to verify connectivity between them. Let me introduce you to the verification steps in detail:

Test connectivity using the ping command:

  • Log in to the switch CLI and try to ping the network segment or device where the media converter is located.
  • If ping returns successfully, the network connection is normal.
  • If ping fails, further troubleshooting of network or device configuration issues is required.

Observe the status indicators of the switch and media converter:

  • Check the various indicators on the switch port and media converter, such as Link, Act, Speed, etc.
  • Normal display of the indicator light indicates that the physical connection is in good condition.
  • If the indicator light is abnormal, there may be a problem with the device or cable.

Check the traffic transmission between network devices:

  • Log in to the switch CLI and use the show interface command to view the traffic statistics of the port.
  • Check the port’s throughput, error count and other indicators to confirm that data can be transmitted normally.
  • If abnormal traffic is found, it may be necessary to further troubleshoot the configuration of the media converter or switch.
