KTI NETWORKS KC-300D-C

KTI Networks KC-300D-C Media Converter

Description

The KC-300D-C from KTI Networks is a compact and durable standalone media converter designed to convert signals between 10/100Base-TX (copper) and 100Base-FX (multi-mode fiber). This device is an excellent solution for extending network distances over fiber optic cable in industrial settings, overcoming the distance limitations of traditional copper Ethernet cables. It includes a power adapter and features DIP switches for easy configuration.

FAQ

Question?

What type of fiber optic cable is required for the KC-300D-C?

Answer:

The KC-300D-C is designed for use with multi-mode fiber (MMF) optic cables. It features an SC connector and supports a maximum distance of 2 kilometers.

Question?

What is the purpose of the Link Fault Pass Through (LFPT) feature?

Answer:

LFPT is a troubleshooting feature. If the link on one port (either fiber or copper) fails, the converter will automatically force the link on the other port to go down. This allows the connected network device to ‘see’ the link failure and react accordingly, for instance by switching to a backup path.

Question?

Can this media converter be powered by a DIN-rail power supply?

Answer:

Yes. While a wall adapter is included, the KC-300D-C also has a terminal block input that accepts a wide DC voltage range (+4.75V to +12.0V). This makes it easy to integrate with standard 24V DC industrial power supplies, provided a suitable step-down converter or a 5V/12V supply is used on the DIN-rail.
