Product Features
Technical Overview
This media converter switch features three ports: two RJ45 copper ports for twisted-pair Ethernet connections and one ST duplex port for multimode fiber optic cabling. It supports Fast Ethernet technology, delivering data transfer rates up to 100 Mbps over both media types.
The fiber optic interface operates at a 1300 nm wavelength, compatible with standard multimode fiber for distances up to 2 kilometers. This extends network segments beyond the 100-meter limit of copper cabling, ideal for connecting buildings, industrial floors, or outdoor installations.
This section brings together practical product details such as Total Number of Ports, Network (RJ-45), Number of Network (RJ-45) Ports, Media Type Supported, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
