This Ethernet fiber switch converts 2 independent 10/100/1000BaseTX twisted pair electrical signals and 1 independent 1000BaseFX optical signal to each other. It uses exchange technology and storeandforward technology to connect two types of network media. Supports dual fiber multimode, dual fiber single mode, single mode single fiber and other optical fiber transmissions. Features adaptive connection to 10M/100M/1000M networks, with storeandforward capabilities for speed adaptation and protocol conversion. Supports a 12K effective media access control address table, with automatic learning and aging of media access control addresses.
