Network Media Converter KTI Networks KC-300D

The 10/100BASE-TX to 100BASE-FX media converter series enables integration of fiber optic and twisted‑pair Ethernet segments, allowing seamless translation between 10BASE-T/100BASE-TX and 100BASE-FX links. The devices include status LEDs for quick verification and support multiple mounting options and fiber interfaces for flexible deployment.

Advantages

These media converters support full wire‑speed conversion and dual 10/100 Mbps operation on the twisted‑pair port. Auto‑negotiation and auto‑MDI/MDI‑X simplify installation. The converters are RoHS compliant, consume low power, and offer link fault pass‑through and far end fault functions to improve network fault detection. They are transparent to 802.1Q VLAN tagged packets and support a wide range of fiber types and reach options.

How to use

Install the media converter on a desktop, wall, or in a compatible center chassis. Connect the twisted‑pair Ethernet cable to the TP port and the fiber optic cable to the FX port using the appropriate connector type. Configure the TP port if required using the user‑accessible settings; the device will otherwise operate with auto‑negotiation and auto‑MDI/MDI‑X enabled. Monitor link and status LEDs for operational verification and use chassis management when installed in a managed center chassis.

Recommendations

Choose the correct fiber connector and mode (multimode or single‑mode) and verify reach requirements before installation. Enable or disable link fault pass‑through according to your network fault‑handling policy and ensure compatibility with 802.1Q VLAN configurations where VLAN tagging is used.
