Netlink Media Converter 10 Base 100 HTB-3100 a/B-25km

A 100Base Media Converter (also known as a Fast Ethernet Media Converter) is a networking device that coverts 10/100Base-TX copper (RJ45) signals into 100Base-FX fiber optic signals. This allows standard Ethernet networks to extend far beyond the 100-meter limit of copper cabling, reaching distances from 2 kilometers to over 120 kilometers
