FAQ
What does this media converter do?
The ComNet CNFE1002S1A converts Fast Ethernet signals from electrical copper (RJ-45) to optical fiber (ST). It allows network traffic to travel over single-mode fiber up to 20 km, extending network reach beyond copper cable limitations while maintaining 100 Mbps data rates.
What types of fiber does it support?
This converter supports single-mode fiber optics. Single-mode fiber uses a smaller core diameter than multimode, enabling longer transmission distances with lower signal loss, making it ideal for runs up to 20 kilometers as specified for this device.
How many ports does it have and what are they?
The converter has two ports: one RJ-45 port for connecting to copper Ethernet networks and one ST port for connecting to single-mode fiber cables. This configuration provides a direct conversion path between copper and fiber media.
What is the maximum distance supported?
The maximum supported distance is 20 kilometers over single-mode fiber. This distance is significantly greater than typical copper Ethernet limits, allowing network segments to span between buildings or across large industrial sites without signal degradation.
How is the converter powered?
Power is supplied via an included AC adapter. The converter does not use Power over Ethernet (PoE) or network-based power, ensuring stable operation independent of the connected network equipment. The adapter is part of the package contents.
Can this converter be mounted in a rack?
Yes, the converter is both wall-mountable and rack-mountable. Its compact dimensions of 6.10" H x 5.30" W x 1.10" D allow installation in standard equipment racks or on vertical surfaces, providing flexibility for various deployment environments.
