Product information

Description

The InLine 66659D Network Media Converter 10/100/1000Mb/s TP to SFP Fiber Optic Single-mode 1310 nm is a reliable networking device designed to seamlessly bridge copper-based Ethernet networks with fiber optic infrastructure. By converting a standard RJ-45 wired connection to an SFP fiber optic interface, this converter enables stable data transmission over long distances using single-mode fiber cables. It supports data rates of 10, 100, and 1000 Mb/s, ensuring high-speed connectivity for demanding network environments.

Equipped with advanced diagnostic features and support for industry-standard networking protocols, this media converter guarantees dependable performance and easy integration into existing enterprise infrastructures. The inclusion of status LED indicators allows network administrators to monitor power supply, link status, and port activity in real time. Its compact black housing enables flexible placement in various professional settings, while support for Auto MDI/MDI-X and automatic duplex negotiation simplifies the installation process without requiring complex configuration.

Advantages

This network media converter provides an efficient way to extend traditional copper networks over long distances using single-mode fiber optics, reaching up to 20 kilometers. It ensures seamless integration between different network media types while preserving signal integrity and high transmission speeds up to 1000 Mbit/s. Features such as Link Fault Pass Through help identify connection issues quickly, minimizing downtime and simplifying ongoing network maintenance.

Suitable for

  • Extending local area networks between different buildings across enterprise campuses
  • Connecting remote network segments over single-mode fiber optic cabling
  • Upgrading existing copper infrastructure to support high-speed fiber uplinks
  • Professional IT environments requiring stable data transmission at 1310 nm wavelength

When it may not be suitable

This device is not designed for multi-mode fiber optic infrastructures and requires compatible single-mode SFP modules to function correctly, as modules are not included in the package. It is also not intended for wireless networking setups or environments that require internal power supplies, as it relies on an external 5V DC power adapter.

Key specifications

  • 10/100/1000 Mb/s maximum data transfer rate
  • TP to SFP fiber optic interface
  • Single-mode fiber mode structure with 1310 nm wavelength
  • Maximum transfer distance up to 20 kilometers
  • Supports IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3z standards
  • Auto MDI/MDI-X and automatic full and half duplex mode negotiation
  • Link Fault Pass Through function for network maintenance
  • LED indicators for activity, power, and status
  • External switching power supply 5V DC/1A

How to use

To set up the media converter, connect your local Ethernet cable from a switch or router to the RJ-45 port. Insert a compatible single-mode SFP fiber optic module into the SFP slot and connect your fiber optic cable. Plug the included external power supply into an electrical outlet and connect the DC power jack to the device. Once powered on, verify the connection using the built-in LED status indicators to ensure proper link activity and network transmission.

What to consider before purchase

  • Verify that your network setup requires single-mode fiber transmission at 1310 nm
  • Ensure you have compatible SFP transceiver modules, as they are not included with the device
  • Check the required distance for your fiber optic link does not exceed the supported range
  • Confirm that an accessible electrical outlet is available for the external power supply

For optimal performance and network stability, always use high-quality single-mode fiber cables and compatible SFP modules. Ensure proper ventilation around the device during continuous operation in professional rack or desktop environments.

Maximum transfer distance: The greatest distance over which the data/signal can be transferred.
20 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.
