Product information

Description

The InLine Network Media Converter 10/100/1000Mb/s TP to SFP Fiber Optic Multi-mode 550m 850nm is a reliable networking device designed to seamlessly bridge copper-based Ethernet networks with fiber optic infrastructures. Featuring a 10/100/1000Mb/s twisted pair interface and an SFP slot, this converter enables smooth data transmission across Fast Ethernet and Gigabit Ethernet environments. It utilizes multi-mode fiber technology operating at an 850 nm wavelength to achieve stable network links over distances of up to 550 meters. Built for professional IT applications, enterprise networks, and campus backbones, this compact converter ensures high performance without requiring complex reconfiguration.

Advantages

This network media converter provides a direct and efficient transition from copper to fiber, allowing existing network hardware to integrate with fiber-optic cabling without extensive structural changes. It supports flexible data speeds on both copper and fiber segments, accommodating various operational requirements. Features such as Auto MDI/MDI-X and auto-negotiation of duplex modes significantly reduce setup effort and configuration time during installation. Additionally, built-in status LEDs and Link Fault Pass Through functionality simplify network maintenance and troubleshooting by providing clear visual indicators of connection states and link status.

Suitable for

  • Extending Gigabit Ethernet and Fast Ethernet connections between remote buildings
  • Bridging copper RJ45 interfaces with multi-mode SFP fiber optic lines
  • Enterprise environments and public institution networks requiring long-distance data transmission
  • Integrating existing copper infrastructure with fiber optic backbones

When it may not be suitable

This device is not suitable for single-mode fiber applications that require transmission distances exceeding 550 meters. Furthermore, it cannot be used without a compatible SFP module, as optics are not included with the unit.

Key specifications

  • Data transfer rate up to 1000 Mbit/s
  • Maximum transfer distance of 550 m
  • Wavelength of 850 nm
  • Multi-mode fiber optic structure with SFP connector
  • Supports 10/100/1000Base-T to 1000Base-FX conversion
  • Networking standards including IEEE 802.3ab, IEEE 802.3u, IEEE 802.3z, IEEE 802.1Q, and IEEE 802.1p
  • Equipped with RJ-45 Ethernet port and SFP fiber port
  • External power supply of 5 V DC / 1 A

How to use

To set up the media converter, connect your twisted pair network cable to the RJ-45 port and insert a compatible SFP transceiver module into the SFP slot with your multi-mode fiber optic cable attached. Plug the included external switching power supply into an electrical outlet and connect the power cable to the device. The converter operates automatically using auto-negotiation and Auto MDI/MDI-X features to establish the link. Monitor the status LEDs on the front panel to verify power supply, link integrity, and network activity during operation.

What to consider before purchase

  • Verify that your network setup requires a multi-mode fiber connection with an 850 nm wavelength
  • Ensure that a compatible SFP module is acquired separately, as it is not included
  • Check that the required transmission distance does not exceed the 550-meter limit
  • Confirm compatibility with your existing Ethernet standards and power availability
Usage recommendations: Install the media converter in a well-ventilated indoor environment away from excessive moisture and heat sources. Always verify fiber connector cleanliness and ensure proper SFP module compatibility prior to initial system startup.

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.

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.
