Product information

Description

The InLine Network Media Converter 10/100/1000Mb/s TP to SFP Fiber Optic Multi-mode 550m 850nm is a reliable device designed to bridge twisted pair copper cabling and fiber optic networks. It facilitates smooth conversion from standard RJ45 Ethernet interfaces to SFP fiber optic connections, allowing networks to span greater distances while maintaining high data transfer rates. Built for professional and enterprise environments, this converter supports multiple IEEE networking standards and ensures stable communication across different network segments.

Advantages

This media converter allows seamless integration of fiber optics into existing copper-based infrastructures without requiring a complete overhaul of current cabling. It supports flexible data speeds on both copper and fiber sides, accommodating various network demands. Operational status is easily monitored through integrated LED indicators and Link Fault Pass Through functionality, which simplifies network maintenance and troubleshooting. Features like auto MDI/MDI-X and auto-negotiation reduce setup complexity and configuration time, ensuring quick deployment in demanding environments.

Suitable for

  • Bridging network connections between different buildings up to 550 meters apart
  • Extending Fast Ethernet and Gigabit Ethernet infrastructures using multi-mode fiber
  • Integrating fiber optic segments into existing copper network environments
  • Connecting remote workstations or sub-networks in enterprise and public institution facilities

When it may not be suitable

This device is not designed for single-mode fiber optic cabling requirements or long-distance transmissions exceeding 550 meters. Additionally, because SFP modules are not included, it may not be immediately operational without acquiring compatible optical transceiver modules separately.

Key specifications

  • Data transfer rates up to 1000 Mbit/s
  • Supports Fast Ethernet and Gigabit Ethernet
  • Maximum transfer distance of 550 meters
  • Multi-mode fiber structure with 850 nm wavelength
  • SFP fiber optic connector interface
  • Ethernet RJ-45 port and single SFP fiber slot
  • IEEE networking standard compliance
  • Input voltage of 5V DC and 1A current

How to use

To set up the media converter, connect your twisted pair network cable from a switch or router to the RJ45 port. Insert a compatible multi-mode SFP transceiver into the SFP slot and connect the appropriate fiber optic cable to the remote network device. Plug the included external switching power supply into a standard electrical outlet and connect it to the unit. The device will automatically negotiate link parameters and use auto MDI/MDI-X to establish communication without manual intervention, while status LEDs display the current power and link activity.

What to consider before purchase

  • Verify that your network setup requires multi-mode fiber connections within a 550-meter range
  • Ensure you have compatible SFP modules, as they are not included with the converter
  • Check that the operating environment supports the external power supply requirements of 5V DC and 1A

For optimal reliability and performance, use compatible multi-mode SFP modules matching the 850 nm wavelength specification and ensure the fiber optic cables are clean and properly connected before powering on the device.

Wavelength: The distance over which a wave repeats itself. The wavelength determines the characteristics of the wave e.g. red light has a different wavelength to blue light.
850 nm
Maximum transfer distance: The greatest distance over which the data/signal can be transferred.
550 m
Maximum data transfer rate: The maximum speed with which data can be transmitted from one device to another.
1000 Mbit/s
Fiber optic connector: This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced.
