Product information

Description

The Digitus Bidirectional Gigabit Media Converter connects wire-based network media to fiber optic infrastructure, enabling reliable data transmission over long distances. It features an RJ45 input interface and an SC fiber optic connector designed for single-mode fiber cables. This device delivers a maximum data transfer rate of 1000 Mbit/s and supports distances up to 20000 meters at a 1310 nm wavelength. Built for wired network expansion, it ensures stable gigabit ethernet connectivity and includes diagnostic LED indicators for power, link, and port status monitoring.

Advantages

This bidirectional gigabit media converter allows seamless migration from copper to fiber network signals without requiring a complete infrastructure overhaul. It incorporates automatic cable detection with auto MDI and MDI-X functions alongside auto-negotiation for full and half-duplex modes. The inclusion of Link Fault Pass Through functionality simplifies routine network maintenance and troubleshooting. Operating with low energy consumption, the device combines reliable performance with compact physical dimensions for flexible deployment.

Suitable for

  • Extending local area networks across long distances up to 20 kilometers
  • Migrating existing copper-based network infrastructure to single-mode fiber optic cabling
  • Connecting remote buildings or network segments via high-speed gigabit ethernet

When it may not be suitable

This device is not designed for multi-mode fiber optic cabling setups and requires compatible single-mode infrastructure to function correctly. It is also unsuitable for wireless networking environments since it relies exclusively on wired connections.

Key specifications

  • Maximum data transfer rate of 1000 Mbit/s
  • Maximum transfer distance of 20000 meters
  • Wavelength of 1310 nm
  • Single-mode fiber compatibility with 9/125 micrometre cables
  • RJ45 input interface and SC fiber optic connector
  • Output voltage of 5 V DC with 0.8 A current
  • Typical power consumption of 2.5 W
  • Operating temperature range from 0 to 60 degrees Celsius

How to use

Connect the copper network cable from your switch or router into the RJ45 port of the media converter. Attach the single-mode fiber optic cable with the SC connector to the designated fiber port. Plug the external power supply into an electrical outlet and connect the DC jack to the device. Verify proper operation by observing the diagnostic LED indicators for power, link, and activity status.

What to consider before purchase

  • Verify that your existing or planned fiber optic cabling is single-mode with 9/125 micrometre specifications
  • Confirm that the transmission distance does not exceed the 20000 meter limit
  • Check compatibility with the corresponding opposite side converter model if pairing devices

Usage recommendations

Ensure the device is installed in a well-ventilated indoor environment within the specified operating temperature range of 0 to 60 degrees Celsius to maintain optimal performance and longevity.

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.
1310 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.
