Welcome to our store! This Ethernet fiber switch can convert 2 independent 10/100/1000Base-TX twisted pair electrical signals and 1 independent 1000Base-FX optical signal to each other. It realizes data exchange between the two types of network connection media by using exchange technology and store-and-forward technology. Supports dual fiber multimode, dual fiber single mode, single mode single fiber, and other optical fiber transmissions. Adaptive connection to 10M/100M/1000M networks, store-and-forward functions to support rate adaptation and protocol conversion. Supports 12K effective media access control address table, supports media access control address automatic learning and aging.
