FAQ
What does this media converter do?
This ComNet converter bridges copper and fiber optic network segments by converting signals between twisted pair Ethernet (via RJ-45 ports) and multi-mode fiber optic cabling (via an ST simplex port). It enables network expansion over longer distances up to 3 km while maintaining Fast Ethernet speeds of up to 100 Mbps.
What types of fiber optic cable does it support?
The converter supports multi-mode fiber optic cables operating at wavelengths of 1310 nm and 1550 nm. It uses an ST simplex connector for fiber connections, which is common in many fiber optic installations for reliable physical connectivity.
What is the maximum distance this converter can support?
It supports a maximum transmission distance of 3 kilometers (approximately 1.86 miles) over multi-mode fiber optic cabling. This extended reach is ideal for connecting network segments across buildings or large facilities where copper cables would face signal degradation or distance limitations.
How many network ports does it have?
The converter has a total of three ports: two RJ-45 ports for twisted pair Ethernet connections and one ST simplex port for fiber optic links. This configuration allows it to handle multiple copper-to-fiber conversions or aggregate connections in a compact unit.
What power source does it require?
It is powered by an included AC adapter, which provides stable electrical supply for consistent operation. The converter does not have internal power storage or PoE capabilities, so it relies on this external power source for all functions.
What is included in the package?
The package includes the ComNet CNFE2002M1B/M media converter unit and a DC plug-in power supply. These components provide everything necessary for basic installation and operation, though fiber optic and twisted pair cables must be sourced separately based on your network requirements.
