## Summary description

The ACT AC4451 is a network media converter supporting data rates up to 1000 Mbit/s. It features various input interfaces including 10Base-T and 1000Base-SX. The converter supports both multi-mode and single-mode fiber optics, ensuring versatile connectivity. With LED indicators for activity and power, it is designed for reliable performance in networking applications.

## Long description

The ACT AC4451 Gigabit Ethernet Media Converter enables conversion between Gigabit Ethernet over fiber and Gigabit Ethernet over copper (RJ45). This unmanaged converter supports data rates up to 1000 Mbit/s and includes an open SFP slot compatible with singlemode or multimode uncoded SFP transceivers. Link Fault Passthrough (LFP) is supported to detect and propagate link failures, and on-board DIP switches allow selection of different operating modes. The unit is compact and finished in black, with LED indicators for power and link/activity.
Advantages
The media converter provides flexible fiber-to-copper connectivity without requiring configuration, supports both multimode and singlemode fiber via the SFP slot, and offers LFP for improved fault visibility. Its unmanaged design and standard Ethernet compatibility (IEEE 802.3, 802.3u, 802.3ab, 802.3z) make it suitable for straightforward integration into existing networks. LEDs and DIP switches facilitate simple installation and basic mode selection.
Suitable for
Extending Gigabit Ethernet links over fiber
Connecting fiber links to existing RJ45 copper switches and devices
Small office or branch deployments requiring simple, unmanaged conversion
Environments needing singlemode or multimode SFP flexibility
Key specifications
Data rate: up to 1000 Mbit/s (Gigabit Ethernet)
SFP: 1 open SFP slot (supports singlemode and multimode uncoded SFP transceivers)
Ethernet standards: IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, IEEE 802.3z
Link Fault Passthrough (LFP): yes
Management: unmanaged
Indicators: LEDs for power and link/activity
Colour: Black
Weight: 0.171 kg
How to use
Install an appropriate singlemode or multimode SFP transceiver into the converter's SFP slot, then connect the fiber cable to the SFP transceiver and an RJ45 Ethernet cable to the copper port. Power the unit and verify LED indicators for power and link/activity. Set the desired operating mode using the on-board DIP switches. No additional configuration is required for basic operation in unmanaged mode.
Usage recommendations
Use compatible uncoded SFP transceivers specified for singlemode or multimode operation and ensure fiber type and connector type match the transceiver. Place the converter in a ventilated location and avoid exposure to moisture. For critical links, enable Link Fault Passthrough to ensure link failures are detected by connected devices.
