Product information

Description

The DIGITUS DN-82123 Bidirectional Gigabit Media Converter RJ45 to SC Single-mode 1000 Mbit/s 1550 nm is designed to bridge wired copper networks and single-mode fiber optic cabling efficiently. It converts standard Ethernet signals to fiber optic signals, enabling reliable high-speed data transmission over extended distances using WDM technology.

Advantages

This media converter allows network administrators to expand existing infrastructure over long distances without replacing current copper-based hardware. It supports automatic cable detection and auto-negotiation for seamless integration, while diagnostic LEDs provide clear visual status monitoring for power, link, and activity.

Suitable for

  • Extending enterprise network reach up to 20 km
  • Connecting remote buildings or facilities via single-mode fiber
  • Migrating existing copper network segments to fiber optic standards

When it may not be suitable

This device is not compatible with multimode fiber optic cabling setups and requires a matching single-mode opposite side device. It also does not support Power over Ethernet (PoE) transmission, meaning connected devices must be powered independently.

Key specifications

  • Data transfer rate up to 1000 Mbit/s
  • Supports 10/100/1000Base-TX to 1000Base-LX conversion
  • 1 RJ45 copper port and 1 SC Simplex fiber port
  • Single-mode WDM technology with 1550 nm wavelength
  • Maximum transfer distance up to 20000 meters
  • Auto-MDI/MDI-X and full/half-duplex auto-negotiation
  • Link Fault Pass Through function for network diagnostics
  • Operating temperature range from 0 to 60 °C

How to use

Connect your copper network cable from a switch or router to the RJ45 port of the media converter. Attach the single-mode fiber optic cable to the SC port, ensuring compatibility with the specified wavelength. Plug in the included external power adapter to power the standalone unit, and monitor the status LEDs to verify link establishment and data activity.

What to consider before purchase

  • Verify that your existing fiber infrastructure uses single-mode cabling with 9/125 µm core and cladding.
  • Ensure a compatible opposite-side converter is available for the bidirectional link.
  • Check the required physical operating temperature and space availability near a power outlet.
Usage recommendations: For optimal network performance and reliable long-distance signal transmission, always pair this unit with the recommended compatible opposite side converter model and inspect fiber connectors for dust or damage prior to installation.

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.
1550 nm
Maximum transfer distance: The greatest distance over which the data/signal can be transferred.
20000 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.
