The device features a multi-mode fiber optic connector (ST) and operates at a wavelength of 1310 nm, allowing for a maximum transfer distance of 2000 m. With LED indicators for link and status, it ensures easy monitoring. Power consumption is low at 2 W, making it an efficient choice for wired connectivity.

## Long description

The KTI Networks KC-300D is a network media converter designed to bridge 100Base-TX copper Ethernet and multi-mode fiber links. Supporting a maximum data transfer rate of 100 Mbit/s and compliance with IEEE 802.3 and IEEE 802.3u standards, it provides a compact solution for extending wired network segments over fiber. The unit includes an ST multi-mode fiber connector operating at a wavelength of 1310 nm and supports link distances up to 2000 m. LED indicators display link and status information while the device operates with low power consumption of approximately 2 W.
Advantages
The KC-300D offers straightforward media conversion between copper and fiber with plug-and-play operation and no complex configuration required. Its support for industry-standard 100Base-TX ensures compatibility with a wide range of network equipment. The combination of an ST fiber connector, 1310 nm wavelength and a 2000 m reach makes it suitable for medium-distance fiber links, while the low power draw and small weight simplify installation in constrained environments.
Suitable for
Extending Ethernet networks over multi-mode fiber between buildings or floors
Connecting network switches and routers to fiber backbone segments
Replacing copper links where electromagnetic interference is a concern
Small office or branch locations requiring a simple copper-to-fiber interface

How to use
Install the KC-300D near the network equipment, connect the 100Base-TX Ethernet cable to the RJ-45 port and attach the multi-mode fiber cable to the ST connector. Power the device using the provided power adapter or compatible power source. Observe the LED indicators to verify link and status; a steady link LED indicates a successful physical connection. No additional software configuration is required for basic operation—once connected, the converter transparently forwards Ethernet frames between the copper and fiber interfaces.
Usage recommendations
For reliable performance, use multi-mode fiber cables and patch cords matched to the ST connector type and maintain clean connector end-faces. Keep fiber runs within the specified maximum transfer distance of 2000 m and verify compatible duplex and speed settings on connected equipment if link negotiation issues occur. Install the device in a dry, ventilated area and ensure the power source meets the converter’s requirements.
