Network Media Converter KTI Networks KC-300D

The KTI Networks KC-300D is a compact network media converter that converts between 100Base-TX copper Ethernet and multi-mode fiber with SC connectors. Compliant with IEEE 802.3 and IEEE 802.3u standards, this unit supports a maximum data transfer rate of 100 Mbit/s and enables fiber links up to 20,000 m at a wavelength of 1310 nm. The device includes LED indicators for link and status, low typical power consumption, and a wide input voltage range, making it suitable for installation in diverse network environments where fiber-to-copper conversion is required.

Advantages

The KC-300D provides reliable 100 Mbit/s media conversion with multi-mode SC fiber support and long-distance transmission capability. Its compliance with Ethernet standards ensures interoperability with existing network equipment. Low power consumption and compact design allow flexible placement and economical operation. Visible LED indicators simplify installation and troubleshooting by showing link status and device activity.

How to use

Install the KC-300D near the copper Ethernet device or fiber termination point and connect the RJ-45 Ethernet cable to the 100Base-TX port. Insert the multi-mode SC fiber connectors into the fiber ports, ensuring correct fiber type and polarity. Provide a stable DC power supply within the 5–12 V range and confirm the LED indicators show link and device status. After connection, verify network communication and adjust adjacent network equipment settings if necessary to match 100 Mbit/s operation.

Recommendations

Use appropriate multi-mode fiber cable and SC connectors rated for the required distance. Maintain proper fiber handling practices to avoid contamination or damage to connectors. For reliable long-distance links, confirm fiber attenuation and connector quality; place the media converter in a ventilated and dry environment and use a regulated power supply within the specified voltage range.
