## Summary description

The LevelOne RJ45 to ST Gigabit Media Converter enables high-speed data transfer over single-mode fiber with a maximum distance of 20km. It supports a data rate of 1000 Mbit/s and complies with IEEE networking standards. The converter features ST fiber optic connectors, LED indicators for link and power status, and operates with a typical power consumption of 5W. Ideal for extending network reach in various applications.

## Long description

The LevelOne Gigabit Media Converter GVT-2003 converts network signals between copper Ethernet and single-mode fiber-optic links. It provides a 10/100/1000Base-T RJ-45 port and an ST fiber connector, supports auto-sensing for 10Base-T/100Base-TX/1000Base-T and can extend a network up to 20 km over single-mode fiber. The unit can operate as a standalone device or slide into a CHV-2000 19" converter rack and functions in ambient temperatures from -10 °C to 55 °C.
Advantages
The converter supports both full-duplex and half-duplex operation, ensuring compatibility with a wide range of network devices. Built-in DIP switches allow quick configuration of Smart LFP (Link Fault Pass-through) modes to monitor and react to link loss on both fiber and copper ports. ST fiber connectivity and gigabit throughput provide compatibility with standard IEEE network equipment while keeping a low power consumption profile for typical deployments.
Suitable for
 Extending Ethernet networks over single-mode fiber up to 20 km
 Connecting copper-based switches or routers to fiber backbone links
 Use in network closets as standalone units or mounted in a 19" converter rack
 Environments requiring IEEE-compliant 10/100/1000 Mbit/s links

How to use
Install the converter near the copper device and connect the RJ-45 Ethernet cable to the 10/100/1000Base-T port. Terminate the single-mode fiber with an ST connector and plug it into the fiber port. Use the DIP switches to select the desired Smart LFP or pass-through modes and verify link and power LEDs for proper operation. The unit can be placed on a shelf as a standalone device or slid into the CHV-2000 19" rack to consolidate multiple converters.
Usage recommendations
For reliable long-distance links, use compliant single-mode fiber cabling and proper ST terminations. Ensure both ends are configured with compatible link settings and monitor LEDs or management tools for link fault indications; consider rack mounting in a CHV-2000 for centralized power and cable management.
